بلاک DMA چیست و چه کاری در FPGA ها انجام می دهد؟

مروری بر ip block های VDMA

همون طور که در بخش axi توضیح دادیم هر تراشه از بلاک هایی تشکیل شده که اطلاعات رو بین هم منتقل می کنن. یکی از این بلاک ها، بلاک DMA هست .

حالا ببینیم این بلاک چه کاری انجام می دهد؟

(DMA (Direct Memory Access

این بلاک برای دسترسی مستقیم به حافظه به کار می‌ره و این امکان رو میده که داده ها از یه بخش سیستم به بخش دیگه منتقل شن‌. ساده ترین کاربردش این هست که داده ها رو از یه قسمت حافظه به قسمت دیگه منتقل می کنه. هم چنین می تونن داده ها رو از هر تولید کننده داده (مثلا ADC) برای هر مصرف کننده داده بفرسته.

(VDMA (Video Direct Memory Access

در این بلاک axi قادر هست اطلاعاتی که در قالب memory mapped هستن رو به stream تبدیل کنه.(این قابلیت در DMA هم وجود داره)

از این بلاک برای پردازش ویدیو در fpga استفاده میشه . در واقع axi این بلاک پهنای باند زیادی داره که می تونه پروتکل های ویدیو رو ساپورت کنه .

خیلی از اپلیکیشن های ویدیو به بافر هایی نیاز دارن که بتونه تغییرات نرخ ارسال فریم ها و همین طور تغییر ابعاد تصاویر رو هندل کنه. و از نکات مثبت این بلاک اینه که این قابلیت رو داره.

در واقع از نقاط قوت این بلاک این هست که میشه پیش پردازش های اولیه رو مثل تغییر رزولوشن , زوم کردن , cropping  و .. انجام داد.

تفاوت های این دو چیست؟

در axi VDMA قابلیت های جدیدی مثل سنکرون کردن فریم های دریافتی با استفاده از بافر های چرخشی ، تغییر دادن رزولوشن و .. وجود داره. ولی در axi DMA دسترسی به حافظه به صورت مرسوم و قدیمی انجام میشه و اطلاعاتی که به صورت stream دریافت میشن به همون ترتیب در DDR های حافظه ذخیره میشن و قابل تغییر نیستن.

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.

I2C Slave IP

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