Description

technical field [0001] The invention relates to the technical field of accelerators, in particular to an accelerator control method and system based on a programmable gate array FPGA. Background technique [0002] The working mode of the accelerator is pulsed, and different timing triggers drive all parts of the functional components to work together. In the traditional accelerator, the timing trigger circuit is composed of discrete devices such as resistance capacitors and digital logic chips, which has low precision and is easily disturbed. Realize timing fine-tuning at the nanosecond level. And once the circuit is determined, new functions cannot be added. Contents of the invention [0003] The object of the present invention is to provide an accelerator control method and system based on a programmable gate array FPGA to solve the problems of low accuracy, susceptibility to interference and poor scalability of existing timing control. [0004] In order to achieve the...
