    Signal Processing: Compression

    Concepts of parallelism:
    Real CPU/DSP implementations very often employ combinations of the following concepts to process/move information/data in parallel and keep units busy for maximum hardware utilization.

    Static:
    determined at compile-time by compiler (often advantageous for systems with predictable behavior, e.g. fixed repetitive numerical algorithm on DSPs or vector computers)
    Dynamic:
    determined at run-time by CPU (often advantageous for systems with non-predictable behavior, e.g. general purpose processors for multi-threaded/process applications)

    Pipeline:
    overlapping execution of subsequent instructions, each instruction is in a different execution stage/phase within the pipeline, fixed cylce-count instruction set advantageous to avoid pipeline stalls, typically called "superpipeline" if stage number >7

    Vector instruction:
    single instruction for identical operation on multiple data elements in parallel (SIMD), multiple parallel units (per pipeline) in CPU

    Multi-function instruction:
    single instruction for non-identical operations on multiple data elements in parallel (not to be confused with VLIW, however sometimes also referred to as VLIW), multiple independent units (per pipeline) in CPU

    Very long/variable length instruction word ("VLIW"):
    grouping of multiple instructions to be executed by CPU in parallel (MIMD), "statically" determined at compile-time (compare with superscalar), multiple pipelines in CPU
    Fixed number ("length"):
    unused slots to be filled with NOPs by compiler
    Variable number ("length"):
    group of instructions encoded (e.g. via link-Bit) by compiler

    Superscalar:
    CPU executes multiple instructions in parallel, "dynamically" determined by CPU at run-time (compare with VLIW), multiple pipelines in CPU

    Instruction-level parallelism ("ILP"):
    CPU issues multiple instructions in one cycle ("multiple-issue"), multiple pipelines in CPU
    Static:
    scheduling determined by compiler at compile-time ("VLIW")
    Dynamic:
    scheduling determined by CPU at run-time ("superscalar")

    Thread-level parallelism ("TLP"):
    execution of multiple threads by CPU in parallel ("simultaneous multi-threading"="SMT")

    Dynamic scheduling:
    CPU reorders instruction sequence at run-time

    Register renaming:
    by CPU at run-time to avoid write-after-read and read-after-write hazards with dynamic scheduling

    Branch prediction:
    speculative execution to avoid cycle overhead with branches/function calls
    Static:
    at compile-time by compiler ("trace scheduling")
    Dynamic:
    at run-time by CPU

    Out-of-order execution:
    dynamic scheduling + register renaming + dynamic branch prediction

    DSP vs. CPU
    :
    By definition, a DSP (Digital Signal Processor) is a specialized CPU, typically used for real-time signal processing purposes in embedded systems. Hereby, some features of general purpose CPUs like memory management (virtual memory, paging) or protection mechanisms (kernel/user modes or memory protection for operating system support) are left out in a DSP design. The main goal is to achive high numerical performance, low interrupt latencies (for real-time), deterministic behavior (for real-time) and low power consumption (for embedded). High data transfer rates by using multiple data and address busses (generalized Harvard architecture), specialized instruction sets for certain numerical algorithms (like the bit-reversed and circular addressing modes for FFT, MAC instructions and zero-overhead loop support for vector operations) and the use of on-chip directly addressable multiport SRAMs (sometimes instead of caches for deterministic behavior) are typical. DSPs are RISC designs (especially load-store architectures), employing pipelines with only a few stages (e.g. 3, in conjunction with on-chip interrupt+loop stacks) to achieve low latencies or pipelines with highly specialized stage sequences. The use of VLIW and other static (and therefore deterministic) parallelizing concepts (like SIMD and multifunction instructions) provides high data throughput und chip utilization. Very often DSPs support massive multiprocessing "farms" (with interprocessor communication ports) and have large multiported register files, 1-cycle MAC-ALUs, Bit manipulation units, powerful address generators (with own register sets), DMA units and multiple I/O units/busses. The number of supported data types is often very limited (e.g. only 32-Bit integer and float). Software (i.e., instruction set binary) compatibility is not important. Typical application fields range from audio/video (e.g. in synthesizers, graphics accelerators, MPEG/JPEG codecs) and telecommunication (e.g. in cell phone tranceiver base stations) to specialized coprocessor designs (e.g. "number crunching") and (where the DSP has its name from) processing of digital signals (e.g. in medical instruments, radar, scientific experimenal setups).
