Abstract

The invention relates to an SOPC (system on programmable chip) software and hardware cooperative system based on Linux, which comprises an SOPC module, a Linux system module and a network server module, wherein the Linux system module comprises a Linux kernel module and a Linux driver module, the network server module comprises a DHCP (dynamic host configuration protocol) server module and an NFS (network file system) server module, and the NFS server module comprises a file system mounting module and a file system interactive module. In the system of the invention, the SOPC and the NFS file system Linux are combined, and the software and hardware cooperative design system based on the combination is realized. The system of the invention has the advantages of fast development flow and simple implementation and is convenient in operation and easy in transplantation and expandability.

Description

Technical field [0001] The invention relates to a device in the technical field of computer operating systems, in particular to a Linux-based SOPC (System-on-a-Programmable-Chip Programmable Chip System) software and hardware cooperative working system. Background technique [0002] At present, with the rapid development of the semiconductor industry, SOPC, as a new form of embedded systems, has been widely used. Using SOPC technology to achieve embedded hardware acceleration, as an emerging system solution model, has its huge development power and broad application prospects. To achieve the above requirements, the collaborative design of software and hardware and the development of IP hard cores are essential . [0003] In some specific applications, pure software system improvement can no longer meet the performance acceleration requirements. At this time, the original software system can be accelerated by re-dividing the hardware and software. The original software is more time...
