Abstract:
A method of formatting images comprising frames of video data comprising the steps of:receiving video data as tokens having a frame rate and an arrival rate;defining at least three buffers for storage of the data, one of said buffers being a display buffer, and another of said buffers being an arrival buffer;generating write addresses for storing data in said buffers;generating read addresses for reading data stored in said buffers;responsive to said step of generating read addresses, displaying data from said display buffer at a display rate; andresponsive to said arrival rate, said display rate, and said frame rate, allocating said buffers to accommodate said steps of generating write addresses and generating read addresses;defining a plurality of 2-wire interfaces each comprising: a sender, a receiver, and a clock connected to said sender and said receiver, said clock having transitions from a first state to a second state, wherein data is transferred from said sender to said receiver upon a clock transition only when said sender is ready and said receiver is ready;providing control signals for controlling said steps of generating write addresses, generating read addresses, and allocating said buffers, wherein said control signals are communicated via said 2-wire interfaces.
