An electronic system provides direct access between a first device and a decoder/encoder and a memory. The electronic system can be included in a computer in which case the memory is a main memory. Direct access is accomplished through one or more memory interfaces. Direct access is also accomplished in some embodiments by direct coupling of the memory to a bus, and in other embodiments, by direct coupling of the first device and decoder/encoder to a bus. The electronic system includes an arbiter for determining access for the first device and/or the decoder/encoder to the memory for each access request. The arbiter may be monolithically integrated into a memory interface of the decoder/encoder or the first device. The decoder may be a video decoder configured to decode a bit stream formatted to comply with the MPEG-2 standard. The memory may store predicted images which are obtained from a single preceding image and may also store intra images. Bidirectional images which are directly supplied to a display adapter may be obtained from two preceding intra or predicted images.
