摘　　要：提出了采用异构多处理器体系结构构建嵌入式计算平台的思想,并基于该思想采用Cortex M3主处理器和MSP430协处理器构建了异构多处理器体系结构的433 MHz有源RFID读写机具。实际验证结果表明,采用异构多处理器构建的嵌入式计算平台实现了计算密集型应用与控制密集型应用的有效分离,大大提高了系统的灵活性和资源分配的合理性。基于该体系结构重构传统嵌入式计算平台时对应用系统透明,使其具有广泛的应用前景。This paper promoted the idea of using heterogeneous multi-processor to build embedded computing platform and built the 433 MHz active RFID reader with Cortex M3 core processor and MSP430 coprocessor based on it. The practical verification result suggested that embedded computing platform based on heterogeneous multiprocessor separated the computing-density application and control-density application effectively, which greatly promoted the flexibility of the system and sensibility of resource allocation. Rebuilding the traditional embedded computing platform based on the heterogeneous architecture is transparent to business application system, which has wide application vision.
