Abstract

A data decommutator architecture for decommutating an input data stream has a sync correlator section for synchronizing the input data stream including a sync code correlator formed of a first field programmable gate array allowing the sync code correlator to be programmed for synchronizing different data formats. A data storage buffer, having two storage banks is coupled to the sync code correlator for receiving sync data, correlator address and correlator write signals. A data decommutator section is provided for decommutating the data received from the data storage buffer. The data decommutator section includes a serial to parallel conversion circuit formed of a second field programmable gate array and a primary decommutating transputer. The second field programmable gate array is programmable to allow decommutation of different data formats. A post processing section receives decommutated data from the primary decommutating transputer via transputer links and provides a post processed decommutated data output. The post processing section includes at least one post processing transputer for processing the decommutated data into post processed decommutated data. The post processing section provides a secondary data output for cascading the data decommutator architecture with another data decommutator architecture to provide further levels of decommutation.
