A method of reducing a set of instructions for execution on a processor extracts information from a first instruction of the set of instructions. The method identifies unencoded space in one or more further instructions of the set of instructions and replaces the unencoded space of the one or more further instructions with the extracted information of the first instruction so as to form one or more amalgamated instructions. The method removes the first instruction from the set of instructions. A method of expanding a set of reduced instructions on a processor is also disclosed.

Reducing a set of instructions for execution on a processor and expanding a set of instructions on a processor

A method of executing an instruction set having a first instruction and a second instruction, includes: reading the first instruction; determining whether the first instruction is integral with the second instruction; reading the second instruction; when the first instruction is integral with the second instruction, interpreting a first operator field of the second instruction to represent a first operator; and when the first instruction is not integral with the second instruction, interpreting the first operator field of the second instruction to represent a second operator, wherein the first operator is different to the second operator.

Executing an instruction set using a prefix to interpret an operator field as either a first or a second operator field

A method of encapsulating a long instruction in a set of short instructions for execution on a processor, the long instruction having k bits and each short instruction having l bits where l&#x3c;k, includes assembling a first portion of the long instruction and a first identifier to form a first instruction of the set of short instructions; and assembling a second portion of the long instruction and a second identifier to form a second instruction of the set of short instructions; wherein at least one of the first and second identifiers is for identifying to the processor that the set of short instructions encapsulates the long instruction.

Assembling long instruction encapsulated in short instructions according to method identified by format bits

A method of executing an instruction set to select a set of registers, includes reading a first instruction of the instruction set; interpreting a first operand of the first instruction to represent a first register S to be selected; interpreting a second operand of the first instruction to represent a number N of registers to be selected; and selecting N consecutive registers starting at the first register S to form the set of registers.

Instruction execution

A method of executing an instruction set including a first instruction and a second instruction, includes reading the first instruction; determining whether the first instruction is an instruction which is integral with the second instruction; reading the second instruction; if the first instruction is integral with the second instruction, interpreting the operand field of the second instruction to indicate at least one value to be used in conjunction with at least one bit of the first instruction; and if the first instruction is not integral with the second instruction, interpreting the operand field of the second instruction to indicate an entry of a look-up table.
