Abstract

The invention relates to the technical field of chip designs, and provides a Nand Flash conversion interface and a data conversion method. The Nand Flash conversion interface includes an uplink conversion module and a downlink conversion module; the downlink conversion module receives a data packet, performs avallon-st decoding on the data packet, and performs Desc decoding on Desc+Data parallel data to obtain a command request and data of a data packet entity; the uplink conversion module receives entity data and a command request, encodes the entity data and the command request to form the Desc+Data parallel data, encodes and generates Desc+Data parallel data conforming to an avalon-st protocol, forwards the Desc+Data parallel data to a PCIE ip end, so that Nand Flash is mounted on a PCIE bus, improves the data transmission efficiency, and reduces the communication delay.

Description

technical field [0001] The invention belongs to the technical field of chip design, and in particular relates to a Nand Flash conversion interface and a data conversion method. Background technique [0002] Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA) has the advantages of fast speed, high efficiency, flexibility and stability, and high integration, so it is very necessary in hardware logic verification and design. In the NandFlash device, because its interface is a traditional memory module interface, but there are various types of mounting buses, it urgently needs an interface protocol that can adapt to a wide range to achieve the purpose of general purpose. [0003] Conventional peripheral interfaces include SATA, USB, eSPI, etc. Due to their protocol and physical hardware limitations, their performance lags behind the current popular pcie4.0, and when there is congestion, PCIe can be adjusted by itself, with short delay and little impact . The co...
