Microcomputer apparatus for executing a given instruction a number of times

Abstract

The invention discloses a microcomputer device, comprising: a processing unit for executing instructions; and a loop counter coupled to the processing unit for receiving and storing a loop according to a loop instruction executed by the processing unit A count value; wherein each time an instruction is executed by the loop, the processing unit decrements the loop count value stored in the loop counter; when the processing unit executes the loop instruction, the processing unit will be in the loop The instruction loop preceding the instruction executes the number of times defined by the loop count value.

Description

Technical field [0001] The invention discloses a microcomputer device, in particular to a microcomputer device used in digital signal processing technology that can quickly and repeatedly execute an instruction multiple times. Background technique [0002] A digital signal processor (DSP) is a common key electronic component in the current electronic age. Basically, the foundation of digital signal processor technology lies in: processing information in digital form (as for information in digital form, it is usually converted from information in analog form). Processing the signal in digital form has more advantages than processing the signal in analog form. One of the main advantages is that the signal can be processed without degrading the signal quality. [0003] In order for the digital signal processor to process the signal efficiently, the operation rate of the signal is usually very fast. The main reason is that most of today's technologies require real-time processing of ...

Problems solved by technology

[0008] However, although the above-mentioned method can improve the operation rate of the digital signal processor chip, this method is still not the best method for using a digital signal processor chip to repeatedly execute the same instruction several times. For example, to repeatedly execute an instruction (For example: adding) several times, the "repeat" instruction will consume one clock cycle, and the first execution of the "add" instruction will consume another clock cycle, that is, the execution of "repeat" This instruction and the first execution of the "add" instruction will each consume one clock cycle, and there is no way to complete the execution within the same clock cycle. This is a problem faced by conventional technologies.
