Embodiment Construction

[0039] In the present invention, the serial peripheral interface device receives PCI Express bus data through a plurality of Buffer switching, in conjunction with Fig. 1a, its concrete process comprises:

[0040] Step 101:

[0041] The serial peripheral interface device sets a plurality of buffers, sets a status register for each Buffer, and sets a Buffer switching register.

[0042] Wherein, when the value in the status register of the Buffer is "1", it means that the data in the Buffer is full; when the value in the status register of the Buffer is "0", it means that there is no data in the Buffer.

[0043] Step 102:

[0044] When it is necessary to receive fast peripheral component interconnection PCI Express bus data, the serial peripheral interface device receives data through one of the Buffers.

[0045] Step 103:

[0046] Detect whether the status register of the Buffer is full, that is, whether the value of the status register of the Buffer is "1", if yes, execute s...

Abstract

The invention discloses a method to receive the PCI Express bus data by a high-speed serial interface device. It includes: many buffers are set out of the serial interface; the serial external interface device receives the data by one of the Buffer when it receives the data of PCI Express bus data, also it can monitor the storage state of the buffer; when the Buffer is full of the data, it will change to the Buffer without data to receive the data continuously.

Description

technical field [0001] The invention relates to a method for fast peripheral component interconnection (PCI Express) bus data transmission, in particular to a method for a serial peripheral interface device to receive PCI Express bus data. Background technique [0002] Peripheral Component Interconnect Express (PCI Express) technology is proposed and developed on the basis of Peripheral Component Interconnect (PCI, Peripheral Component Interconnect) technology. PCIExpress bus technology has many advantages, such as: fast transmission speed, flexible scalability, low power consumption, support for synchronous data transmission, with data packet and layer protocol architecture, each physical link contains multi-point virtual channels, which can maintain end-to-end data Integrity of transmission, with error reporting and processing functions, saving space, and maintaining compatibility with PCI at the software layer. Because the PCI Express bus technology has the above-mention...
