Data processing electronic device possessing double CPU

Abstract

The present invention relates to a data processing electronic device having double central processing unit (CPU) which includes a first central processing unit and a second central processing unit, wherein the first central processing unit is connected to the second central processing unit. The first central processing unit is a lower power type central processing unit and is used for executing a first program (Process) needing long executing time. The second central processing unit is a central processing unit having stronger arithmetic ability than the first central processing unit and is used for executing a second program needing quick arithmetic. The first central processing unit can output interrupt signals to the second central processing unit to order the second central processing unit to execute the second program. The second central processing unit can output interrupt signals to the first central processing unit to order the first central processing unit to transfer the data processed by the first program.

Description

technical field [0001] The invention relates to a data processing electronic device with dual central processing units (CPUs), in particular to a data processing electronic device combining two central processing units with different attributes. Background technique [0002] Existing data processing electronic devices with dual central processing units (CPUs), such as computer motherboards with dual central processing units, are equipped with two central processing units of the same model. This circuit design Not very suitable for some special applications (Applications). Because in some special applications, the data processing electronic device must be able to save power and withstand long-term operation, and the data processing electronic device must deal with a large amount of workload temporarily delivered, such as a large number of computing tasks, and this A large amount of work must be completed in a very short time. Therefore, the circuit design of the data proces...

AI Technical Summary

Problems solved by technology

Therefore, the circuit design of the data processing electronic device must be sufficient for the execution of special application programs for a long time and power saving, and the data processing electronic device must have high-performance computing capabilities. However, the configuration of high-performance computing capabilities It is often the price that must be paid for the high power consumption

In fact, it is difficult to meet the needs of special applications by using two data processing electronic devices with the same type of central processing unit
