A system and method for enabling multithreading in a embedded processor, invoking zero-time context switching in a multithreading environment, scheduling multiple threads to permit numerous hard-real time and non-real time priority levels, fetching data and instructions from multiple memory blocks in a multithreading environment, and enabling a particular thread to modify the multiple states of the multiple threads in the processor core.

Instruction-level multithreading according to a predetermined fixed schedule in an embedded processor using zero-time context switching

A method and system for fixed-length memory-to-memory processing of fixed-length instructions. Further, the present invention is a method and system for implementing a memory operand width independent of the ALU width. The arithmetic and register data are 32 bits, but the memory operand is variable in size. The size of the memory operand is specified by the instruction. Instructions in accordance with the present invention allow for multiple memory operands in a single fixed-length instruction. The instruction set is small and simple, so the implementation is lower cost than traditional processors. More addressing modes are provided for, thus creating a more efficient code. Semaphores are implemented using a single bit. Shift-and-merge instructions are used to access data across word boundaries.

A universal serializer/deserializer ('ser/des') is disclosed that provides hardware implemented modules of those functions determined to be most applicable to a communications protocol. Functionality that is determined to be more unique for a given protocol is implemented in software. Accordingly, a universal ser/des is provided that is able to be used for a plurality of different protocols now known, and configured to communicate with protocols that may be developed in the future.
