DDR controller with multiple AXI interfaces and control method thereof

Abstract

The invention discloses a DDR controller with multiple AXI interfaces. The DDR controller comprises a parameter customizing module, a register configuration module, an interface configuration module,a cache arbitration module and a read-write operation module. The parameter customizing module in the DDR controller allows AXI interface parameters, namely interface configuration parameters, to be flexibly defined, the interface configuration module can instantiate a plurality of AXI interfaces according to the interface configuration parameters, and in combination with the cache arbitration module and the read-write operation module, the access requirements of multiple users for the DDR memory can be met. In addition, the invention further provides a control method of the DDR controller with the multiple AXI interfaces, and the technical effect of the control method corresponds to the technical effect of the DDR controller.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a DDR controller with multiple AXI interfaces and a control method for the DDR controller with multiple AXI interfaces. Background technique [0002] In modern SoC (system on chip) design, with the continuous improvement of SoC design complexity and CPU processing power, the data interaction capability between different design units becomes the key to the design. A high-performance bus structure can enable SoC to obtain smaller area, lower power consumption and better performance. [0003] The AXI (Advanced eXtensible Interface) bus protocol is the most important part of the AMBA (Advanced Microcontroller Bus Architecture) 3.0 protocol proposed by ARM. It is an on-chip bus for high performance, high bandwidth, and low latency. The AXI bus protocol meets the needs of ultra-high performance and complex SoC design, and is widely used in SoC design. [0004] DDR (Double...
