System-on-Chip with Dynamic Adjustment of Voltage/Clock Frequency

Abstract

A system-on-chip that dynamically adjusts voltage / clock frequency is disclosed. The system-on-chip includes multiple data processing modules. The system-on-chip also includes: a voltage / clock supply module, which provides voltage and clocks to the multiple data processing modules; a voltage / clock frequency control module, which receives data from the first data processing module in the multiple data processing modules The first operating state change information is used to control the voltage and clock frequency provided by the voltage / clock supply module to the first data processing module.

Description

technical field [0001] The present invention relates to an on-chip system that dynamically adjusts voltage / clock frequency, more specifically, relates to an on-chip system that can change the voltage / clock frequency provided to the data processing module according to the operating state change information provided by the data processing module . Background technique [0002] System on Chip (SoC) refers to a technology that integrates a complete system on a single chip and packages all or part of the necessary electronic circuits. Such as figure 1 As shown, the SOC of the prior art generally includes a main control microprocessor 10, one or more data processing modules 20-1 to 20-n, one or more memory interface modules MIF30-1 to 30-n and a voltage clock frequency Module 40 is provided. The SOC works with one or more off-chip memories 60-1 to 60-n. [0003] With the increase of integration level and chip area of ​​SOC, effectively reducing the power consumption of SOC chi...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional adjustment method of voltage and clock frequency as mentioned above cannot reflect the performance requirements of each data processing module in real time

Because there is a delay difference between hardware and software in the way of querying the status of each data processing module through the main control microprocessor, and when the number of data processing modules inside the SOC increases, the traditional adjustment method of voltage and clock frequency will Make the real-time performance of software judgment worse
