FPGA connected with a PSRAM memory and a storage system

Abstract

The invention provides an FPGA connected with a PSRAM memory and a storage system. A user layer can communicate with PSRAM through the FPGA. T he FPGA comprises a controller and a physical layer interface module. The controller connects a user design module. The physical layer interface module is connected with the PSRAM. The controller receives a command from a user layer and provides a signal meeting time sequence and sequence requirements for an interface of the PSRAM through the physical layer interface module, and by connecting with the PSRAM, the product cost can be controlled, the control logic can be simplified, the chip area can be reduced, and meanwhile, the purpose of high-speed transmission can be achieved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an FPGA connected with a PSRAM memory and a storage system. Background technique [0002] IP core (Intellectual Property Core, Intellectual Property Core) refers to a module provided by a party in the form of a logic unit or chip design. Designers can use IP cores as the basis for logic design of ASICs or field programmable logic gate arrays to shorten the design cycle and improve design quality and efficiency. [0003] PSRAM (Pseudo static random access memory, pseudo static random access memory) is a DRAM technology and technology, similar to SRAM RAM devices, compared with SRAM using 6T technology, PSRAM uses 1T+1C technology, PSRAM The capacity is much larger than SRAM, the volume is lighter, the price is much cheaper than SRAM, and the price is more competitive, and the I / O interface protocol of PSRAM is the same as that of SRAM. Compared with DRAM, PSRAM use...
