 I2C Master IP

I2C Master IP is a type of Intellectual Property (IP) that implements the I2C Master protocol. It is used to interface a device as a master on an I2C bus and allows the device to communicate with slave devices. An I2C Master IP core sends commands and data to the I2C slaves and receives data from them. It provides a standardized interface for communication between the master device and the slave devices, enabling communication and control of the slave devices. The I2C Master IP is commonly used in a wide range of applications, such as in embedded systems, IoT devices, and consumer electronics.

Improving Design Productivity and Quality with Specification Automation

Designing semiconductor devices has always been a distinct specialty of engineering, but today’s designers face immeasurably greater challenges. A typical system-on-chip (SoC) design has billions of transistors, thousands of intellectual property (IP) blocks, hundreds of I/O channels, and dozens of embedded processors. Chip designers need all the help they can get.

Three Keys for Faster, Better Design

Assistance comes in three forms: abstraction, automation, and reuse. Virtually all chip design today occurs at the register transfer level (RTL), enabling much greater productivity than manually crafting gates or transistors. This level of abstraction is therefore much more efficient, making it possible for a single designer to create entire IP blocks or even subsystems.

RTL design is also amenable to automation; generating gate-level netlists automatically via logic synthesis is part of what makes the design process so efficient and productive. Just about every aspect of the test insertion, power management, layout, and signoff flow that follows RTL design is automated as well. Without this approach, modern SoCs simply would not be possible.

The third form of assistance is design reuse. Especially for standard IP blocks and interfaces, there is no value-add in reinventing the wheel by designing from scratch. EDA vendors and dedicated IP providers offer a huge range of reusable designs, most in RTL form. Designers often need this IP to be configurable and customizable, so it may come from a generator rather than as a fixed design.

Register Automation Is the Foundation

All three forms of designer assistance come together in specification automation, starting with the registers in the design. SoCs typically have a huge number of addressable (memory-mapped) registers defined by the chip specifications. These registers form the hardware-software interface (HSI) by which the embedded software and system drivers control the operation of the hardware.

Manually writing RTL code for all these registers is tedious and error-prone. Fortunately, the Agnisys IDesignSpec™ Suite makes it easy to automatically generate the register RTL design. Using the IDesignSpec GDI interactive tool or the IDS-Batch™ CLI Batch Tool, designers create their RTL files at the push of a button every time the register specification changes. 

These tools accept many register and memory specification formats, including spreadsheets, SystemRDL, IP-XCAT, and the Portable Stimulus Standard (PSS). Designers can specify many widely used special register types, including indirect, indexed, read-only/write-only, alias, lock, shadow, FIFO, buffer, interrupt, counter, paged, virtual, external, and read/write pairs. 

Registers are just one part of a chip that can be specified abstractly and generated automatically, fostering reuse and improving quality of results (QoR) with proven design IP. Another example is interfaces to standard buses such as APB, AHB, AHB-Lite, AXI4, AXI4-Lite, TileLink, Avalon, and Wishbone. The RTL design generated by IDesignSpec Suite includes any interfaces requested.

Any necessary clock-domain-crossing (CDC) logic across asynchronous clock boundaries is also included in the generated design. For safety-critical chip applications, designers can request that safety mechanisms such as parity, error-correcting code (ECC), cyclic redundancy check (CRC), and triple module redundancy (TMR) logic be included as well.

Most chips contain standard design elements such as AES, DMA, GPIO, I2C, I2S, PIC, PWM, SPI, Timer, and UART. Designers specify these blocks with many degrees of configuration and customization, and the Agnisys IDS-IPGen™ design tool generates the RTL design code. IDS-IPGen also generates finite state machines (FSMs) and other design elements for custom IP blocks.

Automating SoC Assembly

As noted earlier, SoCs contain thousands of standard and custom IP blocks. All of these must be connected together into the top-level chip design. Like register design, manually writing the RTL code for this stage is a tedious and error-prone process. Block inputs and outputs change many times over the course of a project, and updating the top-level RTL code by hand is extremely inefficient.

The Agnisys IDS-Integrate™ design tool, another part of the IDesignSpec Suite, automates the chip assembly process. Designers specify the desired hookup using a simple but powerful format that includes wildcards to handle buses and collections of signals with similar names. IDS-Integrate automatically generates the complete top-level RTL design.

For IP blocks with standard buses, IDS-Integrate automatically generates any required aggregators, bridges, and multiplexors, including them in the top-level RTL design. For example:

AHB interfaces on two IP blocks can be aggregated into a single bus

An AHB-to-APB bridge can connect IP using AHB and IP using APB

With the burden on SoC designers growing all the time, they need to specify at the highest possible level of abstraction, take advantage of automation, and reuse whenever possible. The specification automation capabilities of the Agnisys IDesignSpec Suite provide all three forms of designer assistance, providing the industry’s most complete solution.

Designers no longer have to hand-write RTL code for registers, memories, standard bus interfaces, aggregators, and bridges, CDC logic, safety mechanisms, custom IP elements, standard IP blocks, and top-level design. Abstract specification and automation improves productivity; reuse of proven IP improves quality of results. 

Customization and configuration options ensure that designers do not have to sacrifice any flexibility to achieve these benefits. Many other project teams—verification, validation, embedded software, bringup, and documentation—also benefit from specification automation. The reasons to select Agnisys as a design partner are truly compelling.

Benefits of AXI4 Stream DMA:

AXI4 Stream DMA (Direct Memory Access) is a type of hardware block that is used in digital circuits and computer systems to transfer data between a peripheral device and memory without involving the main CPU.

In an AXI4 Stream DMA, the peripheral device sends data to the DMA engine, which then transfers the data to the memory. Similarly, when the peripheral device needs to receive data, it sends a request to the DMA engine, which retrieves the data from memory and sends it to the peripheral device. This process allows for faster data transfers and frees up the CPU to perform other tasks.

The AXI4 Stream DMA is part of the ARM Advanced Microcontroller Bus Architecture (AMBA), which is a set of interconnect protocols for creating complex SoCs (System on Chips). The AXI4 Stream DMA is designed to work with the AXI4 interconnect protocol, which is widely used in modern SoCs.

The benefits of using AXI4 Stream DMA include

Faster data transfer speeds compared to traditional CPU-based transfers

Reduced CPU usage, which allows the CPU to focus on other tasks

More efficient use of system resources, which can lead to improved overall system performance

Lower power consumption compared to traditional CPU-based transfers

Scalability and flexibility, allowing for easy integration with various peripheral devices and memory architectures.

Overall, AXI4 Stream DMA is a useful hardware block for achieving high-speed and efficient data transfer in digital circuits and computer systems.

AXI DMA with Scatter-Gather: Streamlining Data Transfer in Embedded Systems

In the world of embedded systems, efficient and fast data transfer is of utmost importance. This is where Direct Memory Access (DMA) comes into play. DMA technology allows data to be transferred directly between memory and peripherals, bypassing the need for the CPU to handle each transfer individually. This greatly speeds up the transfer process and frees up the CPU to focus on other tasks. But what if the data you need to transfer is not stored in contiguous blocks in memory? The capacity of AXI DMA scatter gather to capture data in this situation is useful.

Scatter-Gather: Breaking Down Data into Smaller Blocks

 The scatter-gather feature of AXI DMA enables the transfer of non-contiguous blocks of data in a single transaction. Instead of transferring the data as a whole, it breaks it down into smaller, contiguous blocks and transfers them individually. This allows for a more flexible and efficient data transfer process, especially for applications that require large amounts of data transfer, such as video and image processing.

 Efficiency and Performance Boost with Scatter-Gather

 The scatter-gather feature of AXI DMA has several benefits for embedded systems.

 Firstly, it eliminates the need for copying data     into contiguous blocks in memory, saving both time and resources. 

Secondly, it provides a more efficient use of memory,     as non-contiguous data can be stored in its original form, without being     rearranged into contiguous blocks.

Finally, the scatter-gather feature greatly improves     the performance of data transfer, as it allows for parallel processing of     multiple blocks of data. This results in faster transfer speeds and a more     efficient use of resources, making it ideal for applications with large     amounts of data transfer.

In short, AXI DMA's scatter-gather capability offers an adaptable and effective method for data transfer in embedded systems. This capability can simplify the procedure and significantly enhance the performance of your system, whether you're working with non-contiguous blocks of data or need to transfer massive volumes of data.

AXI DMA Scatter Gather and Its Features

The direct memory access (DMA) controller grants a hardware subsystem to access the main memory with nominal supervision from the central processing unit (CPU). This reduces CPU workload when the system transmits vast amounts of memory multiple times. The DMA Controller core provides a system to transfer data between memory and AXI4-stream interface using direct mode or scatter-gather mode.

Characteristics

Memory interface in AXI4 full-duplex or AXI3 half-duplex

Programmable memory interface width

Control and status register with APB3 interface

Up to 8 channels of AXI4-stream interface

Programmable stream interface width

Enhance bandwidth with hardware read and write queue

Priority-weighted round-robin scheduling

Backups scatter-gather mode

Includes example design targeting the Trion® T120 BGA576 Development Board

AXI DMA Scatter Gather allows the application to specify a list of transactions in memory that the hardware will action without more application interference. During this time, the application can add more work to keep the Hardware busy.

User can confirm the completion of transactions through polling the hardware, or interrupts. AXI DMA Scatter Gather processes complete packets. A packet refers a series of data bytes that represent a message. AXI DMA Scatter Gather allows a packet of data to be scattered into one or more transactions. For instance, take an Ethernet IP packet that comprises of a 14 byte header followed by a 1 or more bytes of payload. With SGDMA, the application may point a BD to the header and another BD to the payload, and then transmit them as a single message. This tactic can make a TCP/IP stack well-organized by allowing it to keep packet header and data in separate memory regions instead of gathering packets into the closest blocks of memory.
