Abstract

The invention discloses a PCI bus and FPGA-based printing data acquisition and processing system. The PCI bus and FPGA-based printing data acquisition and processing system comprises a PCI card. The PCI card is provided with a data processing unit and a plurality of sub detection devices which are connected with the data processing unit through a PCI bus and are used for acquiring printing data; the data processing unit includes a processor module as well as a PCI interface module, a data-caching module and an output interface module which are connected with the processor module; and each sub detection device includes a micro controller module as well as a printing data acquisition module, a display module and a power source which are connected with the micro controller module, wherein the power source module provides required electric energy for the micro controller module, the display module and the printing data acquisition module.

Description

technical field [0001] The invention relates to a data collection and processing system, in particular to a printing data collection and processing system based on PCI bus and FPGA, which belongs to the field of data collection and processing. Background technique [0002] From the establishment of the specification in 1992 to now, the PCI bus has become a standard bus for computers. The standard system structure composed of PCI bus is shown. The PCI bus replaced the earlier ISA bus. Of course, there is an AGP bus specially used for graphics cards behind the PCI bus, and the current PCI Express bus, but PCI can be used from 1992 to the present, which shows that it has many advantages, such as plug and play (Plug and Play), interrupt sharing, etc. . Here we give an in-depth introduction to the PCI bus. [0003] In terms of data width, the PCI bus has 32bit and 64bit; in terms of bus speed, there are two types: 33MHz and 66MHz. 32bit33MHz is currently popular, and 64bit s...
