Abstract

The embodiment of the invention provides a field programmable gate array (FPGA) and an automatic configuration method thereof, which belong to the technical field of FPGAs. The FPGA automatic configuration method comprises steps: compressed data stored in a flash are acquired, wherein the compressed data comprise a compressed instruction and / data; the compressed data are decoded through a preset compression algorithm; the decoded instruction and / or data are inputted to a configuration control circuit, wherein the configuration control circuit configures the FPGA according to the instruction and / data. Thus, on the basis of not increasing the use difficulty of a user, capacity expansion is carried out on the FPGA.

Description

technical field [0001] The invention relates to the technical field of field programmable gate array FPGA, in particular to a field programmable gate array and an automatic configuration method thereof. Background technique [0002] With the wide application of Field-Programmable Gate Array (FPGA: Field-Programmable Gate Array), higher requirements are put forward for the convenience of the FPGA configuration method and the cost of the system. Among many FPGA configuration methods, the FPGA automatic configuration method based on flash memory, compared with other FPGA configuration methods, has been widely used due to its user convenience and lower system cost, and has become the mainstream FPGA in the industry. Configuration method. [0003] At present, there are mainly two kinds of FPGA automatic configuration methods based on FLASH: the FPGA automatic configuration method based on the serial FLASH outside the FPGA chip and the FPGA automatic configuration method based on...
