A method of converting 10-bit pixel data (e.g. 10:10:10:2 data) into 8-bit pixel data involves converting the 10-bit values to 7-bits or 8-bits and generating error values for each of the converted values. Two of the 8-bit output channels comprise a combination of a converted 7-bit value and one of the bits from the fourth input channel. A third 8-bit output channel comprises the converted 8-bit value and the fourth 8-bit output channel comprises the error values. In various examples, the bits of the error values may be interleaved when they are packed into the fourth output channel.

Guaranteed data compression

A data processing architecture includes an input device that receives an incoming stream of data packets. A plurality of processing elements are operable to process data received from the input device. The input device is operable to distribute data packets in whole or in part to the processing elements in dependence upon the data processing bandwidth of the processing elements.

SIMD array operable to process different respective packet protocols simultaneously while executing a single common instruction stream

An input/output system transfers data packets to and from a SIMD array of processing elements (PEs) such that different sizes of data packets are transferred to respective ones of the PEs. The packets are transferred in batches to respective different addresses in the array under the control of the PEs. Transfer to or from the array may be carried out when either a batch or part of a batch is ready for transfer. The decision to transfer either full or part batches is made in dependence upon the speed of the PEs and the speed and intermittency of the data packets.
