Abstract
A method and system for expanding an instruction set by decoding an instruction located at a particular address using one or more of those address bits in conjunction with the instruction word.
Claims14
A method of processing an instruction, said method comprising:
- fetching said instruction using a corresponding address from a memory unit, wherein a first meaning is associated with said instruction stored at said corresponding address by a processor with a first bit position from said corresponding address concatenated with said instruction, and wherein a second meaning is associated with said instruction stored at said corresponding address by said processor with a plurality of bit positions from said corresponding address concatenated with said instruction, wherein at least one of said plurality of bit positions is different from said first bit position;
- concatenating a portion of said corresponding address to said instruction to form an extended instruction;
- and
- executing said extended instruction.
1 more element
A method, comprising:
- generating said instruction, wherein a first meaning is associated with said instruction stored at a corresponding address by a processor with a first bit position from said corresponding address concatenated with said instruction, and wherein a second meaning is associated with said instruction stored at said corresponding address by said processor with a plurality of bit positions from said corresponding address concatenated with said instruction, wherein at least one of said plurality of bit positions is different from said first bit position;
- storing said instruction at a particular address in a memory unit;
- and
- before executing said instruction, fetching said instruction using said particular address from a memory unit and concatenating said portion of said particular address to said instruction.
1 more element
A system comprising:
- a memory unit for storing a plurality of instructions at a plurality of addresses;
- and
- a processor operable to fetch a particular instruction from said memory unit by providing a corresponding address, wherein a first meaning is associated with said particular instruction stored at said corresponding address by a processor with a first bit position from said corresponding address concatenated with said particular instruction, and wherein a second meaning is associated with said particular instruction stored at said corresponding address by said processor with a plurality of bit positions from said corresponding address is concatenated with said particular instruction, wherein at least one of said plurality of bit positions is different from said first bit position, and wherein said processor is operable to concatenate a portion of said corresponding address to said particular instruction before executing said particular instruction.
