采集

This paper presents a design method of an off-line portable scanner, which can be used without computer. We discuss the system based on a synchronous Digital Signal Processor with multicenter, which is used to gather data with high speed. TIs TMS320VC5402 is a sixteen-bit fix processor, and we make it the core of our control system. Because it can not only handle data with high speed but also manipulate the data by abundant arithmetic/logic operations and determine the results of processing which can be output quickly as images.
