DSP采集处理系统初态自检优化设计方法

Optimized Original State Design of DSP Acquisition and Processing System

探讨了DSP系统初态设计的实际意义,提出了自下而上分级自检设计的一般优化原则,实现对器件级,功能级和状态级的初始优化智能自测试、自诊断和自修复.按上述原则设计了DSP图像采集处理系统自检.对扫描成像识别自检测试表明,开机复位系统进入指定初始态,初始同步频率扰动和初相补偿测试表明系统快速收敛于稳定初态,证明了该初始状态优化设计方法是可靠的.

A hirarchy selftest design was discussed. General principle of hierarchy selfchecking design from bottom to top is presented to fulfill intelligent selftest, selfdiagnosis and self-recovery from device to function to state. Optimized selftest design of image acquisition and processing system were described base on the above principles. The selfchecking of rosette scan, imaging and recognition were executed. The system enters a definite state after resetting. Original synchronous frequency error was convergent and original phase error turns to zero. This proves that the system converges a stable original state quickly. This also proves that the selftest design is feasible.
