    We deal with parallelism at the data level. We describe an implementation of the architectural technique called sub-word parallelism (SWP), which increases parallelism at the data-element-level by means of partitioning a processor's data path. The specific implementation we focus on is based on the TigerSHARC DSP architecture, developed at Analog Devices, Inc. As a result of SWP, the same data pat... View full abstract»

    Markets have always influenced the central thrust of the semiconductor industry. Beginning in the early eighties, the personal computer (PC) market has been the dominant market influencing the semiconductor industry. Single-chip microprocessors (MPUs) enabled what became the huge PC market, which ultimately overshadowed the earlier minicomputer and mainframe computer markets. The popularity of PCs...

    The processing delay is a serious constraint for speech communication. A one-way end-to-end delay of more than 150 ms can severely degrade the quality of real-time conversations. The components of the total system delay includes the speech frame size, the look ahead, other algorithmic delays, multiplexing delay, processing delay for computation, and transmission delay. At the transcoder rate adapt... View full abstract»

    The number and variety of products that include some form of digital signal processing (DSP) has grown dramatically. DSP has become a key component in many consumer, communications, medical, and industrial products, which use a variety of hardware approaches to implement DSP, ranging from the use of off-the-shelf microprocessors to field-programmable gate arrays (FPGAs) to custom integrated circui...

    Software decoding of Dolby Digital (an adaptive transform-based coder using a frequency-linear, critically sampled filterbank) allows it to become a baseline capability on the personal computer (PC), with greater flexibility than a hardware approach. Intel's MMX technology provides instructions that can significantly speed up the execution of the Dolby Digital decoder, freeing up the processor to ... View full abstract»
