Executing instructions for managing constant pool base register used for accessing constants during subroutine execution

摘要

A constant data accessing system having a constant pool comprises a computer processor having a constant pool base register, a compiler having a constant pool handler, and an instruction set module having a constant pool instruction set unit. The constant pool base register is configured to store a value of constant pool base address of one or a plurality of subroutines which have constants to be accessed.

1. A constant data accessing system, comprising:
a constant pool comprising a pool of constants; a compiler having a constant pool handler, the constant pool handler accessing the constants; an instruction set module having a constant pool base register management instruction set unit and a constant pool access instruction set unit; a computer processor having a constant pool base register configured to store a value of a constant pool base address, wherein the value of the constant pool base address is an address of a subroutine, and the subroutine comprises the constants; instructions, in the constant pool base register management instruction set unit, configured to manage the value of the constant pool base address, wherein the operation of managing comprises saving, setting, or restoring the value of the constant pool base register, and the operation of managing is performed before accessing the one or the plurality of constants; and instructions, in the constant pool access instruction set unit, configured to access the constants, using the constant pool base register.
