Abstract of the Disclosure A multiple channel data acquisition system for the transfer of large amounts of data from a multiplicity of data channels. The system includes a plurality of modules which operate in parallel to convert analog signals to digital data and transfer that data to a communications host via a FASTBUS. Each module has a plurality of submodules which include a FEB connected to input circuitry having an analog to digital converter and a cache memory for each of a plurality of channels. The submodules are interfaced with the FASTBUS by a FASTBUS coupler which controls a module bus, and a module memory. In addition, a local processor is provided to control the transfer of data from the FEBs to the module memory. The system is triggered to make a rapid sampling of data in parallel and store that data to the cache memories. The cache memories are unloaded to the FEBs during which zero suppression occurs. The data in the FEBs is reformatted and compressed by the local processor during transfer to the module memory. The FASTBUS coupler is used by the communications host to upload the compressed and formatted data from the module memory. The local processor executes programs which are downloaded to the module memory through the FASTBUS coupler.
