Abstract

The invention discloses a processor starting method based on an FPGA and a processor. According to the technical scheme, the method comprises the following steps: running a solidification starting bootstrap program, and obtaining an off-chip storage unit mapped by a processor from a processor core address space and used for downloading an embedded program image file; loading the embedded program image file in the off-chip storage unit corresponding to the address field to an on-chip instruction storage unit; and running the embedded program image file in the on-chip instruction storage unit. When the embedded program needs to be updated, the technical scheme can avoid reloading the processor kernel hardware design, reduce the development complexity and improve the development efficiency.

Description

technical field [0001] The invention relates to the field of FPGA technology, in particular to an FPGA-based processor starting method and processor. Background technique [0002] Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA) is widely used in various fields. The FPGA-based processor has good scalability, and designers can freely expand the functions of the processor according to different application scenarios, which is conducive to rapid design and use. [0003] The technicians of this technical solution found during research and development that the existing FPGA-based processor startup method, after completing the processor core hardware design, writes the startup bootloader and embedded program image files into the initial memory of the on-chip instruction storage unit. value; when running the startup boot program in the initial value of the on-chip instruction storage unit, run the embedded program image file from the initial value of the on-chip...
