Abstract
A system and method for low delay mode operation video decoding embodied in a prefetch buffer and an mbcore including an mbcore pipeline. The mbcore is adapted to check a status of the prefetch buffer at predetermined times and to implement a low delay mode to delay the mbcore pipeline when a data level of the prefetch buffer goes below a threshold at the predetermined times. The mbcore is adapted to ensure that there is a sufficient quantity of data in the prefetch buffer for a particular operation and, in a preferred embodiment, is adapted to check the status of the prefetch buffer at a start of a slice, at a beginning of dct decoding of each coded block. The prefetch buffer and the mbcore operate asynchronously, with the mbcore being adapted to prevent a symbol from splitting between the prefetch buffer and the mbcore.
