Problems solved by technology

at this time, figure 1 The components 16 in the circuit board 10 no longer exist in the circuit board 10. If there is a need to download data to modify the contents of the FPGA, the NVRAM needs to be taken out and written in with an existing recorder or other methods, which solves the cost Waste problem, but it will cause inconvenience during research and development and increase the difficulty of user-end products if there is a version update or function upgrade

Embodiment Construction

[0029] figure 2 A block diagram of a downloading system of a field programmable gate array (Field Programmable Gate Array, FPGA for short) of the present invention is shown. exist figure 2 Among them, the system mainly includes: a host computer 21, to provide a source of data (data) downloaded to the field programmable gate array; a first download circuit 201, used to transmit information, which is used for updating data at the download end, and provides A control signal controls the download program; a second download circuit 202 is used to receive information from the first download circuit and write it into a non-volatile random access memory (Non-Volatile Random Access Memory, referred to as NVRAM). The non-volatile random access memory can be a flash memory (not shown); after the data from the outside is written into the non-volatile random access memory and the update of the data code is completed, it can be read in at this time To a main field programmable gate arra...

Abstract

The invention provides a method for downloading data to a field programmable gate array (FPGA) repeatedly, the character lies in, it uses a complex program logic device (CPLD) to configure and write into a nonvolatile random access memory (NVRAM) and write into a field programmable gate array, and matches with a connector which contains a testing circuit, which is used to judge if the invention uses the connector to connect according to the test state by input the testing circuit to FPGA control function CPLD element, if the state is logic low, then executes and read the data in NVRAM and writes into FPGA.

Description

technical field [0001] The present invention relates to programmable devices (programmable devices), especially a method and device for repeatedly downloading data to a Field Programmable Gate Array (Field Programmable Gate Array, FPGA for short), which is easily re-configured The Field Programmable Gate Array increases the convenience of research and development (R&D) and upgrade (upgrade), thereby saving the cost of product development and the speed of upgrade. Background technique [0002] In the field of integrated circuit (IC) design, because field programmable gate array elements (FPGA devices) can provide opportunities for IC design simulation and test errors, it has been widely used in multimedia, workstations, electronic communications and networks in recent years. IC design development. [0003] The structure of field programmable gate array element (FPGA device) mainly adopts two design modes of static random access memory base (SRAM Base) and anti-fuse (Anti-fus...
