Risc Microcontroller Design And Standardization

This paper mainly discussed the design and standardization of 8 bit RISC microcontroller. The high level design methodology was used to implement it. It analyzed every step of the integration and the design flow of this methodology, with a focus on the design. This subject was supported by the national defence project--"The Applications of SoC In The New Generation Battleplan" .The main research content of this subject is to design an 8 bit RISC MCU core, which has the independent intellectual property right. The instruction system of this MCU and the PIC16CXXX microcontroller's are totally compatible.There are mainly five parts in this paper.1. At the function demand and the analyses of instruction system, we finished the architecture design and the division of the function modules.2. Introducing the analyse and design of the control path in detail, including the control module, instruction code module and interrupt control module.3. Introducing the analyse and design of the periphery function parts in detail, including the Compare/Capture/PWM part and the I2C bus controller.4. After simple introduction of the current IP standard , we discuss the standardization of our RISC MCU core.5. We finished the functional simulation with the testing programs , synthesized the system with EDA tools and then implement it in FPGA device.This paper not only introduced the design of RISC MCU core ,but also discussed its standardization. That has contributed a lot to the design of the more complex SoC design.
