[0043] This implementation mode focuses on optimization for the power consumption problem. In the overall platform, the power consumption is mainly composed of two parts: the power consumption of the interface module chip (such as USB, IIC, SDIO, etc.) and the processor core. Through experimental testing, in the heterogeneous multi-core processor based on ARM, DSP and FPGA described in the first embodiment, the energy consumed by the three processors accounts for the vast majority of the entire system. The power consumption of three processors can reduce the power consumpt...

Abstract

The invention provides a heterogeneous multi-core processor based on an ARM, a DSP and an FPGA and a task scheduling method, and relates to technologies of heterogeneous multi-core processors. The heterogeneous multi-core processor based on the ARM, the DSP and the FPGA aims to solve the problems that a conventional multi-core processor is poor in environmental adaptability, parallel processing capability and resource control capability. The heterogeneous multi-core processor based on the ARM, the DSP and the FPGA comprises the ARM, the DSP, the FPGA and peripheral interfaces, wherein data transmission is carried out among the ARM, the DSP and the FPGA, and the peripheral interfaces comprise the RS232 interface, the CAN bus interface, the SPI interface and the USB interface. An electricity supply module for software implementation is embedded in the FPGA and used for controlling electricity supply of the ARM, the DSP and the FPGA. According to the heterogeneous multi-core processor based on the ARM, the DSP and the FPGA and the task scheduling method, the different peripheral interfaces can be dynamically reconstructed in real time according to different interface requirements, and the resource utilization rate and the environmental adaptability are improved remarkably; software can be loaded into different processors, and parallel running of hardware is achieved truly. The heterogeneous multi-core processor based on the ARM, the DSP and the FPGA and the task scheduling method are suitable for an embedded application environment.

Description

technical field [0001] The invention relates to heterogeneous multi-core processor technology. Background technique [0002] With the development of integrated circuits, microprocessor technology has entered the deep submicron stage. Nowadays, the number of integrated circuits in the vast majority of processors active in the market has reached the order of 100 million, and the operating frequency of processors has also risen rapidly. But the ensuing problem is that the power consumption and heat generation are huge, which also determines that it is not suitable for the mobile environment. Therefore, many processor manufacturers are currently developing multi-core processors to achieve the purpose of reducing power consumption as much as possible while increasing processing speed. [0003] The multi-core processors used today can be divided into two types according to the types of internal processor cores: homogeneous multi-core processors and heterogeneous multi-core proce...
