Embodiment Construction

[0038] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0039] Table 2 shows typical dynamic instruction usage for an ARM-based core. Among all instructions, the dynamic usage rate of data movement is 43%, and the control flow rate is 23%. Other instructions such as arithmetic operations, comparisons, and logical operations account for 34% of dynamic usage rates. Arithmetic logic units (ALU) is a part of a computer that performs various arithmetic and logic operations. The basic operations of the arithmetic unit include four arithmetic operations of addition, subtraction, multiplication, and division, logical operations such a...

Abstract

The invention discloses an embedded multi-microcontroller core switch chain structure comprising at least two microcontroller cores. The microcontroller cores process data in a multi-microcontroller core system and are arranged according to static leakage current, and the smaller the static leakage current is, the toper the microcontroller cores are. The microcontroller cores are connected in series. The invention further discloses an operating method of the embedded multi-microcontroller core switch chain structure. Energy efficiency is improved under ultra-deep submicron process, so that effective utilization rate of energy sources such as batteries can be improved.

Description

technical field [0001] The invention relates to the field of on-chip systems, in particular to an embedded multi-micro-controller core switch chain structure and a working method thereof. Background technique [0002] Multi-core refers to the integration of two or more complete computing engines (cores) in one processor. The development of multi-core technology to simply increase the speed of a single-core chip would generate too much heat without corresponding performance improvements, as has been the case with previous processor products. At that rate in previous products, the heat generated by the processor would quickly exceed the surface of the sun. Even without the thermal issues, the price / performance ratio is unacceptable, with slightly faster processors costing a lot more. [0003] Such as figure 1 As shown, when a single core increases the frequency of work (increases the working speed), when performing the same task, the power consumption will increase signific...
