SIGNAL PROCESSING APPARATUS

摘要

A signal processing apparatus for processing signals like video, audio or graphics contains signal processor units that produce and consume a stream of data items relating to samples along at least one dimension of an at least one dimensional physical signal. The processor units communicate the data via a memory. Memory address indicators indicating the regions in memory where the data-items are stored are passed between the processor units via a FIFO channel. The control signal outputs of the FIFO channel are use to provide synchronization between the processor units.
