Processor and method of indirect register read and write operations

摘要

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.
