configurable multi-channel IO direct connection type microprocessor system

Abstract

The invention relates to a configurable multi-channel IO direct connection type microprocessor system which comprises a microprocessor kernel, a memory module and a voltage conversion module, and themicroprocessor kernel is connected with a peripheral device through an AXI bus, an AHB bus and an APB bus. According to the system, a user can directly carry out multi-class and multi-group bus connection on the microprocessor core, and the microprocessor peripheral is directly connected with the microprocessor core through different bus interfaces. According to the system, the microprocessor kernel can control microprocessor peripherals, and reading and writing are not affected by other modules.

Description

technical field [0001] The invention belongs to the technical field of configurable microprocessors, in particular to a configurable multi-channel IO direct connection type microprocessor system. Background technique [0002] A microprocessor is a central processing unit composed of one or a few large-scale integrated circuits. These circuits perform the functions of control components and arithmetic logic components. The microprocessor can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components, and is the operation control part of the microcontroller. [0003] In traditional microprocessor system designs, the microprocessor occupies only a small area of ​​the chip. Other parts are memory, clock generation and distribution logic, system bus, and peripherals. In the traditional microprocessor system design, the bus architecture, peripheral interfaces and functions of the microprocessor...

AI Technical Summary

Problems solved by technology

In the traditional microprocessor system design, the bus architecture, peripheral interfaces and functions of the microprocessor are constrained. A microcontroller has fewer types and quantities of buses, and the microprocessor core can only provide AXI bus Or AHB bus, AXI bus or AHB bus are converted by the bus bridge to control the peripherals of the microprocessor, so the bus peripherals are not rich enough to meet all application scenarios

At the same time, due to the traditional microprocessor system bus architecture, when one bus path in the bus architecture is occupied, other bus paths cannot be used
