Processor device with timed interruption function

Abstract

The invention relates to a processor device with a timed interruption function. The processor device comprises an internal hierarchy, an intermediate hierarchy and a top hierarchy, wherein the internal hierarchy is a processor inner core, and comprises a special destination register, a decrypting and executing flow line used for processing an instruction step by step, and a bypass module and a flow line freeze module which are used for controlling the running of a flow line; the intermediate hierarchy comprises a processor core, and an external interface and a memory which are connected with the processor core respectively; an interruption module and a timer are also arranged in the processor core; the timer is connected with the interruption module and the special destination register respectively; the interruption module is connected with the processor inner core; the top hierarchy comprises a debugging interface, a bus line and a direct memory access module; the debugging interface is connected with the processor core; the direct memory access module is connected with the bus line and the memory respectively; the bus line is connected with the processor core. Compared with the prior art, the processor device with the timed interruption function has the advantages of high efficiency, quick response and the like.

Description

technical field [0001] The invention relates to the field of processor architecture, in particular to a processor device with a timer interrupt function. Background technique [0002] Digital Signal Processor (DSP) is a microprocessor with a special structure, which is specially used to process large-scale digital signals. The real-time running speed of special-purpose digital signal processors is generally faster than that of general-purpose processors. Its main feature is powerful digital computing capabilities, so it is mainly used in fields involving large-scale digital information calculations. Digital signal processors (DSPs) have become increasingly important chips in the digital world. [0003] With the rapid development of high technology, the function requirements of digital signal processor (DSP) are getting higher and higher. For example, the corresponding waiting for the external device can be realized by repeatedly inquiring the external device by executing t...
