Parameterized specific instruction set processor design platform

Abstract

The invention discloses a parameterized specific instruction set processor design platform comprising a universal register number selection module, a bus bit width selection module, a data memory type selection module, a program control instruction selection module, an arithmetical logical operation instruction selection module, a target processor generation module and a retargetable assembler. The design platform generates the optimal specific instruction set processor core which saves most resources in the structure frame of the specific instruction set processor core according to related parameters selected by a user for different application fields, and also shortens the design period of the specific instruction set processor. The retargetable assembler is capable of positioning the compiler to the target processor according to the parameters selected by the user, and further capable of translating an assembler source program into the machine codes of the target processor; as a result, the work load of a programmer is reduced; therefore, the working efficiency is improved.

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of this patent application technology is that the hardware structure of the special-purpose instruction set processor is fixed. For different application fields, this architecture has poor adaptability and low resource utilization. The Design Cycle of an Instruction Set Processor

In addition, the tailored circuit does not have special assembler support, and the application of this special instruction set processor needs to write machine code, which increases the workload of programmers and reduces work efficiency
