Implementation of advanced peripheral bus interface for MV10 MCU

MV10 is an MCU which consists of PWM, ADC,CAN and some other function blocks. It is designed for car body’s control. Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals. This paper presents an implementation of APB interface for MV10 MCU. After that, MV10 can be integrated into any AMBA system on chips (SoCs) easily. We have built a multi-core system with ABMA to verify this design. In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB. Before building this system, some operations are encapsulated into a task with dedicated ID. MV10 works as a co-processor with ARM by acquiring task ID from ARM. The result of simulation indicates that MCU can work well as expected. Based on our design, MV10 can be mounted on any AMBA system from now on.
