A data processing system includes a producer processor that produces a sequence of data outputs for use by consumer processors of the data processing system. The system also includes a memory for storing a sequence of data outputs produced by the data processor. The data processor encodes data outputs as encoded blocks of data, storing a particular encoded block of a first frame in a first location in the memory and an indication of the first location. The data processor stores a corresponding encoded block of a second data output in a second location and updates the indication to the second location.
