Problems solved by technology
[0003] However, the interface of most peripheral devices is usually a RAM interface and does not have an AXI bus interface. When the SOC uses the AXI bus, the peripheral device needs to develop an additional AXI bus interface to allow the processor and the peripheral device to perform data interaction. waste of resources

Embodiment Construction
[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of this application.
[0046] Embedded system is a hot spot in the development of today's computer industry. With the rapid development of VLSI, the semiconductor industry has entered the era of deep submicron. The feature size of devices is getting smaller and smaller, and the chip scale is getting bigger and bigger. Integrating millions to hundreds of millions of transistors. Such dense integration allows us to integrate the functions previously realized by several chips such as CPU ...

The invention discloses a communication method and device based on an AXI bus and a medium, and the method comprises the steps: receiving a bus signal through the AXI bus, then converting the bus signal into an RAM interface signal, converting an address signal in the RAM interface signal into a simplified address adaptive to each peripheral device according to the address of each peripheral device, and transmitting the address signal to the AXI bus; and finally, notifying each peripheral device to execute a corresponding action according to the simplified address of each peripheral device and the corresponding data signal. By adopting the technical scheme, after the bus signal of the AXI bus is received, the bus signal is analyzed, and the bus signal is converted into the RAM interface signal suitable for the RAM interface, so that more peripheral equipment can realize communication with the processor through the AXI bus without additionally developing an AXI bus interface, and the waste of resources is reduced. And moreover, the total address signal is optimized, so that the size of the signal is reduced, the data can be quickly stored, and the release speed of the bus permission is improved.
Description
technical field [0001] The present application relates to the field of SOC technology, in particular to a communication method, device and medium based on an AXI bus. Background technique [0002] SOC is called a system-on-chip, also known as a system on a chip, which means that it is a product, an integrated circuit with a dedicated purpose, which contains a complete system and has all the content of embedded software. The bus is the connector in the SOC, which realizes the communication between the processor and various peripheral devices. A high-performance SOC has higher and higher requirements on the performance of the bus. The AXI bus is a high-performance, high-bandwidth, and low-latency multi-channel transmission on-chip bus. Its address, control, and data phases are separated, and it supports unaligned data transmission and out-of-order access, enabling SOC to be smaller Smaller area, lower power consumption, and better performance, so it is widely used.
