<P>PROBLEM TO BE SOLVED: To provide a new command function which reduces dependency on an architecture resource, such as a general-purpose register, improves a function and performance of a software version using a new command, and is consistent with existing architecture. <P>SOLUTION: A computer uses one set of general-purpose registers (GPR). The respective GPR include a plurality of parts. A program, such as an operation system and application which operates in a large capacity GPR mode, accesses the whole GPR, but a program, such as application operating in a small capacity GPR mode, can only access one part at a time. In the small capacity GPR mode, a command operation code can determine which part to access. <P>COPYRIGHT: (C)2012,JPO&INPIT |
