Abstract

The present invention provides a method and apparatus of converting a stream of pixel data (120) in space and time into a stream of bitplane data. In particular, the presnt invention converts the pixel data (120) stream according to a predetermined output fromat. The apparatus of the present invention receives the pixel data (123) in a 'real-time' fashion, and dynamically performs predefined permutations so as to accomplish the predeined trnspose operation. Alternatively, the pixel data are stroed in a storage medium (126), and the apparatus of the present invention retrieves the pixel data and performs the predefined permutation to accomplish the predefined transpose operation. The methods and apparatus disclosed herein are especially useful for processing a high-speed stream of digital dat in a flow-through manner and suitable for inplementation in a hardware video pipeline. The control signal fanout and gate count of this invention are reduced compared to currently available similar techniques for converting pixel data into bitplane data.
