| 摘 要： | 提出了基于非均匀存储器存取(nonuniform memory access,NUMA)非对称多处理器模型的制导用信号处理平台方案。介绍了用商用VME64单板计算机和TMS320C6X系列数字信号处理器实现该多处理器模型的方法。设计了TMS320C6XDSP的各VME64接口互连逻辑,所有模块均用VHDL语言设计,并在FPGA上实现。已实现了一个基于该多处理器模型的最小的基本系统,解决了某制导信号处理系统的数据传输瓶颈问题,简化了系统硬件设计复杂性,提高了系统工作的可靠性和稳定性。

| Abstract: | A scheme to construct the signal processing platform for underwater intelligent guidance using nonuniform-memory-access asymmetric multiprocessor model is proposed. The multiprocessor system is implemented by VME64-based commercial standard single-board computer and TMS320C6X serial digital signal processors. The VME64 interface modules and interruptor module of slave processor ( TMS320C6X DSPs ) are designed, through which the design of multiprocessor system is simplified and the bottleneck of data transfer of guided signal processing system is solved. The robustness and the stability of systems are improved. |
