Instruction programmable buffer design system based on processor debugging architecture

Abstract

The invention relates to an instruction programmable buffer area design system based on a processor debugging architecture, and the processor debugging architecture is generally composed of a debugging interface module, an interface conversion module, a debugging module and a processor core. The interface conversion module converts serial data into parallel data and achieves access to the debugging module, and software debugging personnel control the debugging process of the processor core through the debugging module. According to the invention, the design of the instruction programmable buffer area is realized in the hardware design of the debugging module, so that software debugging personnel can quickly and conveniently download the instruction to the processor core for operation. Three different instruction programmable buffer designs are provided, debugging can be carried out independently and can also be matched with one another according to different use scenes, and debugging of the processor core is achieved more efficiently.

Description

technical field [0001] The invention relates to the technical field of processor core design, in particular to an instruction programmable buffer design system based on a processor debugging architecture. Background technique [0002] In the processor design process, without a fully functional debug system, the designer's understanding and control of the current state of the processor will drop dramatically as the design progresses from tool simulation to hardware verification to final silicon implementation. , the controller's internal state at runtime is equivalent to a "black box" to the designer. The development and debugging of processor software and hardware will be greatly limited due to the lack of debugging methods. [0003] For embedded platforms, the debugger software generally runs on the host PC, and the debugged processor is often on the embedded development board, which is a typical scenario of cross-compilation and remote debugging. The debugger software ne...
