Embedded Multi-Processor OS and Intelligent Agent Mechanism

摘要

This paper discussed embedded operating system in the asymmetric inhomogeneous multi-processor architecture. All of multi-processor resources are described to the virtual computer conception, which can be managed by operating system for application program. An embedded operating system supporting multi-processor is designed to two layers architect: object layer related and unrelated with processor. Embedded multi-processor operating system not only has resource management function of single-processor operating system but only provide application program with a uniform interface by building up the uniform system calls module. The efficient communication mechanism must be established synchronously among multi-processor and intelligent agent mechanism by uniform system calls module provided to application program. On the TI's dual-core processor TMS320VC5471 EVM, such an embedded multi-processor operating system is formed by μ CLinux in ARM subsystem and μ COS in DSP subsystem.
