Even though minicomputers and microcomputers are larger and faster than ever before, they have not kept pace with the demands of telemetry users. Hardware preprocessor of telemetry data has been used in distributed telemetry computer system for processing all data at extremely high rates. According to the requirements and characteristics of telemetry data processing, a distributed multiple data stream hardware preprocessor with multiplex microcomputers of telemetry data is introduced in the paper. Each data stream is processed by three microcomputer models coupled in multi-computation architecture. The microcomputer models consist of TMS320C25 in the preprocessor. The preprocessor owns the features of wavefront array processors. A time-wait procedure can be done in pipeline processing and large data processing can be derived in parallel processing and pipeline processing.
