A kind of FPGA-based at96 bus controller ip core and its construction method

Abstract

The invention relates to an AT96 bus controller IP (internet protocol) core based on an FPGA (field programmable gate array), which comprises an AT96 bus interface module, an AT96 bus controller state machine module, a FIFO (first in, first out) cache module, a local bus control module, a local bus interface module and a function configuration module, wherein one end of the AT96 bus interface module is connected to an AT96 bus interface card while the other end is connected to the AT96 bus controller state machine module; the AT96 bus controller state machine module is connected to the FIFO cache module; the FIFO cache module is connected to the local bus control module; the local bus control module is connected to the local bus interface module; and the function configuration module is connected to later four modules. A construction method for the AT96 bus controller IP core based on FPGA comprises the following six steps: 1) design input; 2) function simulation; 3) logic composition; 4) pre-simulation; 5) a table file output; and 6) an IP core calling module output.

Description

1. Technical field [0001] The invention relates to the application of interconnection of communication single boards through the AT96 bus interface, in particular to an FPGA-based AT96 bus controller IP core and a construction method thereof, belonging to the technical field of communication equipment design and application. 2. Background technology [0002] In order to apply AT96 bus PCs in harsh industrial environments, the German SIEMENS company initiated the formulation of the AT96 bus European card standard (IEEE996) in 1994, and it has been popularized and applied in Europe. AT96 bus = AT96 bus electrical specification + 96-core pinhole connector + Eurocard specification (IEC297 / IEEE 1011.1). The AT96 bus industrial computer eliminates the golden finger connection between the templates, and has the ability to resist strong vibration and impact; its 16-bit data bus, 24-bit addressing capability, high reliability and good maintainability are more suitable for use in hars...
