Method and device for debugging FPGA (field programmable gate array) in MCU (microprogrammed control unit) chip

Abstract

The embodiment of the invention provides a method and a device for debugging an FPGA (field programmable gate array) in an MCU (microprogrammed control unit) chip. The FPGA module is integrated into the MCU chip. The FPGA module comprises an FPGA device; the method comprises the steps of writing preset hardware description information and IO distribution information into the FPGA device; generating a corresponding software drive program according to the hardware description information; configuring IO pins of the FPGA device according to the IO distribution information; loading the software drive program into the MCU chip; performing system reset on the MCU chip and executing the software drive program. The right use of the FPGA in the MCU chip can be ensured, when data information has errors, the errors can be timely found and solved, so the FPGA can be normally used and the stability of the FPGA is improved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a method for debugging FPGA in an MCU chip and a device for debugging FPGA in the MCU chip. Background technique [0002] With the continuous improvement of integrated circuit technology, field programmable gate array FPGA (Field-Programmable Gate Array) appears as a semi-custom circuit in the field of application-specific integrated circuit (ASIC, Application-Specific Integrated Circuit), the logic block of FPGA And the connection can be changed according to the user's needs, and the logic blocks inside the FPGA can be connected through editable connections, so the FPGA can complete the required logic functions. [0003] Due to the extremely high flexibility of FPGA, MCU (Micro Control Unit, Micro Control Unit) chip manufacturers hope to integrate FPGA into MCU chips to solve the contradiction of different functional requirements of MCU chips in different application...

Problems solved by technology

[0005] However, when the FPGA with the corresponding functions programmed is integrated on the MCU chip, the FPGA may not be able to perform its corresponding functions, and the data information may be wrong. When the data information is wrong, the FPGA will not work normally. The logical functions of the FPGA cannot be played normally, and the MCU chip integrated with the FPGA will also fail, resulting in the unusability of the FPGA and poor stability of the FPGA.
