Title:
FIELD PROGRAMMABLE GATE ARRAY AND CIRCUIT FUNCTION CHANGEOVER METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/088184
Kind Code:
A1
Abstract:
A field programmable gate array (FPGA) and a circuit function changeover method in the FPGA. The FPGA comprises a programmable input/output module, a programmable wiring module, and a programmable logic module. An ith circuit in a first circuit set in the programmable input/output module, the programmable wiring module, and the programmable logic module comprises a changeover switch and Ni sets of static random access memories (SRAMs), wherein Ni is an integer greater than or equal to 2, and i is a positive integer; each of the Ni sets of SRAMs is connected to the changeover switch; each SRAM is used for storing a binary file corresponding to a circuit function; the changeover switch is used for changing from, according to a changeover signal received by the changeover switch, outputting a binary file stored in a first SRAM in the Ni sets of SRAMs to outputting a binary file stored in a second SRAM in the Ni sets of SRAMs. The FPGA can reduce the circuit function changeover time of the FPGA, thereby satisfying the real-time circuit function changeover requirement for the FPGA.
