Indirect Addressing (epo) Patents (Class 712/E9.04)
  • Executing instructions for managing constant pool base register used for accessing constants during subroutine execution
    Patent number: 8972705
    Abstract: 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.

  • Processor and method of indirect register read and write operations
    Patent number: 7383420
    Abstract: A processor is operable to carry out a method that comprises accessing a first register based on a program instruction and obtaining a first register-out value, accessing a second register based on the first register-out value and obtaining a second register-out value, and storing the second register-out value into a third register based on the program instruction. The processor is further operable to carry out a method that comprises accessing a first register based on a program instruction and obtaining a first register-out value, accessing a second register based on the program instruction and obtaining a second register-out value, and storing the first register-out value into a third register based on the second register-out value.
