Embodiment Construction

[0077] In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment will be described in detail below together with the accompanying drawings.

[0078] Figure 4 A microprocessor according to the invention is shown. Fetch unit 410 is connected to decode unit 415 , vector request signal 465 , and branch request signal 470 . The decode unit 415 is connected to the execution unit 420 . Execution unit 420 is connected to data memory access unit 425 and back to read unit 410 . The data memory access unit 425 is connected to a register write-back unit 430 and a memory 460 . The register file 405 is connected to the read unit 410 , the decode unit 415 , the execute unit 420 , and the register write-back unit 430 . Communication between units is maintained.

[0079] The bus interface unit 435 communicates with the fetch unit 410 using a memory request 440 , also referred to as a read request 440 , addr...

Abstract

A method of reducing processor inefficiency that results from a branch or vector instruction. Since vector or branch instruction results in new instructions, certain prefetched instructions are unneeded. A method that usurps the prefetched instruction and replaces it with the vector or branch instruction is disclosed.

Description

technical field [0001] The present invention relates to pipelined processing, and more particularly to a microprocessor having pipelined circuitry that can occupy and wait for pipelined bus requirements. Background technique [0002] Pipeline processing is a method of information processing. A pipeline is made up of different units that perform work on messages. Information is worked in every unit of the pipeline. After the first unit completes its work on the information, the first unit passes the information to the other unit. Work on the message continues until the message has passed through all units in the pipeline. [0003] The advantage of the pipeline is that it can increase the throughput per unit time. So that in fewer cycles (cycle), more instructions (instruction) can be processed. [0004] Although pipeline processing can increase the speed of instruction processing, it still has considerable problems when processing vector or branch instructions. Branch o...
