Abstract: A novel data transfer scheme for efficiently transferring data between multiple data generating processing units in a processing element wherein each processing unit may generate data at different rates. The data output of each processing unit is multiplexed into a single data stream and written to a memory buffer. A centralized software processor such as a CPU or DSP implements a demultiplexer operative to read the contents of the input buffer, demultiplex the data and distribute it to individual unit buffers thus recreating the original data streams generating by each of the processing units. The multiplexed data stream is generated by partitioning the outputs of the data generating processing units into multiple multiplexer groups based on individual data rates. The outputs of the various groups are collected by a multiplexer and used to build a single data stream having a well-defined structure.
