A loading method, device and system for a field programmable gate array

Abstract

The embodiment of the invention discloses a method, a device and a system for loading a field programmable gate array. A cache region is arranged to judge whether the data volume stored by the cache region is within a preset range or not, if yes, the incomplete filled indication of the data volume stored by the cache region is sent to a processor to indicate the processor to continuously transmit data so as to continuously acquire data transmitted through a data bus by the processor, and if not, the to-be-filled indication of the data volume stored by the cache region is sent to the processor to indicate the processor to stop transmitting data. Not only is the reliability of the loading data ensured not to carry away data, but also the fast loading is achieved to avoid the loading gap. Furthermore, data of multiple periods is transmitted through a data bus, and a feedback signal read by an indication signal triggering processor is sent again, so that the method for loading is configured more flexibly, the device for loading is more optimized, and the loading performance of the system for loading the whole field programmable gate array is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method, device and system for loading a field programmable gate array. Background technique [0002] At present, Field Programmable Gate Array (Field Programmable Gate Array, referred to as FPGA) technology is widely used in various application-specific integrated circuits. It is the most integrated technology and the best choice for improving system integration and reliability for small batch systems. one. The working state of the FPGA chip is set by the program stored in the RAM in the chip. Therefore, the RAM in the FPGA chip needs to be programmed and configured. Users can use different configuration methods to apply to the FPGA chip, so every time the power is turned on, the FPGA chip needs to be loaded with programs before the FPGA chip can be used normally. Therefore, when using FPGA chips, data and program loading technology is an indispensable application, and lo...
