Abstract: An integrated circuit includes a processor and a program memory device on a common substrate. The memory device is able to deliver to the processor VLIW instructions with at least m operative fields. The memory device comprises: a dictionary memory comprising dictionary instructions each having at least m dictionary elementary instructions; an instructions memory having primary instructions each associated with a VLIW instruction and containing its data, the address of a dictionary instruction, and m masking bits; and m selection devices respectively controlled by the masking bits and each delivering either an NOP instruction, or the dictionary elementary instruction corresponding to the masking bit, so as to reconstruct, by combination with the data of the primary instruction, the VLIW instruction.

Abstract: Dolby AC-3 and MPEG-2 audio permit the transmission of audio signals in packet form, via more than two independent audio channels. If a reproduction device has only a two channel audio decoder an external multi channel audio decoder may be used for multi channel audio reproduction. In this instance, packetized signal is received by a first decoder and is decoded for a first mode of reproduction and applied to a reproduction device. The received signal is unpacked in the first decoder and stored in memory. The stored signal is reformatted for application to a second decoder for decoding and reproduction according to a second mode of reproduction.
