High-performance low-power-consumption embedded processor based on command dual-transmission

Abstract

The invention provides a high-performance low-power-consumption embedded processor based on command dual-transmission, comprising a command fetching unit, a two-way decoding unit, a transmitting unit, a command dispatch execution control unit, a command executing unit and a loading / storing unit; wherein the command fetching unit is used for pre-fetching two commands in a single clock cycle and sending the commands into an assembly line; the two-way decoding unit is used for parallelly decoding the two commands in the single clock cycle; the transmitting unit is used for parallelly transmitting the two commands in the single clock cycle; the command dispatch execution control unit is used for dynamically adjusting the command dispatch according to the computing load and controlling execution according to an out-of-order execution mechanism; the command executing unit is used for computing the results of the commands; and the loading / storing unit is used for ensuring that when the commands are absent, sequent commands can successfully occupy the assembly line and visit the data memory on the disc and the data memory outside the disc. The invention can improve the performance of the embedded processor and reduce the cost under the precondition of low power consumption.

Description

technical field [0001] The invention relates to an embedded processor, in particular to an embedded processor with high performance and low power consumption. Background technique [0002] Embedded systems refer to computer systems that are oriented to specific application fields and perform specific tasks, and are usually composed of four parts: embedded processors, peripheral hardware devices, embedded operating systems, and user applications. Embedded systems are ubiquitous and have penetrated every corner of the national economy: in consumer electronics, such as digital cameras, DVD players, and printers; in medical equipment, such as cardiac arrhythmia monitors and cardiac pacemakers ; In automobile design, such as fuel filling system and automatic braking system. Embedded systems will play a vital role in the national informatization strategy. [0003] The embedded processor is the core component of the embedded system. The embedded processor is responsible for runn...
