Apparatus and method for initializing system global variables by using multiple load/store instructions

摘要

An apparatus and method for initializing system global variables by using a multiple load/store instruction is disclosed. The apparatus includes: a first storing unit for storing a system global variable initialization function and initialization functions using multiple load/store instruction; a second storing unit for storing a return address; a control unit for storing a first return address to the second storing unit when the system global variable initialization function is called for initializing the system global variable, initializing the system global variables by calling the initialization functions using multiple load/store instruction while performing the system global variable function and performing a rest of system global variable initialization function by finding and executing an execution sequence based on the first return address stored in the second storing unit; and a third storing unit for storing the system global variables initialized according to the control unit.
