Embodiment Construction

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0023] figure 1 It is a structural diagram of a general processor of the present invention, the general processor device includes:

[0024] The program address generator is used to generate the address for fetching instructions in the stage of processor fetching instructions;

[0025] The pipeline controller performs specific judgment and control during the operation of the processor to avoid various conflicts with hardware resources;

[0026] External interrupt controller and kernel interrupt control mechanism;

[0027] A specific special register in the processor initializes and controls the interrupt processing mode;

[0028] The general set of registers in a processor, and specific register windows within it.

[0029] like figure 1 , the pipeline in the processor is divided into different pipeline stages, such as figure 1 In the embodimen...

Abstract

The invention relates to an interrupt real-time processing micro-architecture which comprises a program address generator, a pipeline controller, an interrupt controller, a special register and a general register group. The micro-architecture can be used for quick response of an interrupt mechanism of an on-chip processor system and supporting a mode configurability function of an interrupt response mechanism. The circuit is easy to implement and small in area, and the performance of the processor can be further improved.

Description

technical field [0001] The invention belongs to the fields of computer hardware, processor design, processor interrupt processing and digital integrated circuit design, and in particular relates to a processor interrupt real-time processing circuit and a design and realization method. Background technique [0002] Patent US5768599A describes an interrupt management mechanism for an embedded operating system, which involves an interrupt information storage unit and a switch interrupt management mechanism to solve the delay problem between system calls and interrupt responses. Patent US4930068A invented an interrupt processor, which relates to a processing mechanism of different modes of an interrupt execution unit. Patent CN102426538B invents an interrupt response device and method, which specifically relates to a programmable interrupt processing module, which forms a mechanism of multiple interrupt processors together with the CPU, and belongs to the optimization problem of...
