Abstract:
The invention provides an application specific instruction set processor (ASIP) that uses a Very Long Instruction Word (VLIW) for simultaneously executing a plurality of operations. For simultaneously executing the plurality of operations, the ASIP processor comprises a fetching unit to fetch a long instruction word from an instruction memory unit and an instruction decoder unit that interfaces with the fetching unit and a program address counter. The instruction decoder unit decodes the long instruction word fetched from the instruction memory unit and enables a plurality of sub blocks responsible for execution of a plurality of simultaneous independent operations. The instruction decoder unit of the ASIP is capable of decoding a 32-bit instruction word and executing up to six simultaneous independent operations.
