1. computer-implemented method;

  • Be used for expanding effective number of the GPR that can be used for programmed instruction of the computing machine of big general-purpose register (GPR) with first number;

    Each instruction comprises operational code and the one or more GPR fields that are used to specify corresponding GPR;

    Each big GPR comprises first and second portion, and said big GPR comprises first little GPR that is made up of first and the second little GPR that is made up of second portion, and said method comprises;

    , in little GPR pattern, carry out a)-b) in response to said computing machine;

    A) instruction of execution first instruction set;

    Said first instruction set is used to visit the said first little GPR;

    Said execution comprises that generating the storage address that is used for the access memory operations number based on the said first little GPR perhaps visits the first little GPR operand, and the wherein said first little GPR is made up of said first;

    AndB) instruction of execution second instruction set;

    Said second instruction set is used to visit the said second little GPR;

    Said execution comprises that generating the storage address that is used for the access memory operations number based on the said second little GPR perhaps visits the second little GPR operand, and the wherein said second little GPR is made up of said second portion;

    AndIn response to said computing machine in big GPR pattern;

    Carry out the instruction of the 3rd instruction set, said execution comprises that generating the storage address that is used for the access memory operations number based on said big GPR perhaps visits the big GPR operand that comprises said first and said second portion.
