A method, medium and apparatus for storing and restoring a register context for a fast context switching between tasks is disclosed. The method, medium and apparatus may improve overall operating speed of a system by increasing the speed of context switching. The method may include adding an update code for updating information of live registers to a task file that includes a code of a task to perform a specified function, converting the task file having the update code added thereto into a run file, updating the information of the live registers with the update code during running of the task using the run file, and storing a live register context according to the updated information of the registers.

A method of declaring and using variables includes; determining whether variables are independent variables or common variables, declaring and storing the independent variables in a plurality of data structures respectively corresponding to the plurality of processors, declaring and storing the common variables in a shared memory area, allowing each one of the plurality of processors to simultaneously use the independent variables in a corresponding one of the plurality of data structures, and allowing only one of the plurality of processors at a time to use the common variables in the shared memory area.

A method of reducing a code size of a program by controlling a control flow of the program using software in a computer system is disclosed. The method includes the steps of storing a first program count of a first instruction in a first buffer when an error occurs while the first instruction having an Operand including Offset and Length is being executed among a plurality of instructions loaded in the code memory, changing a current program count of the code memory to a second program count which is obtained by adding the Offset to the first program count, storing a second instruction, which is located at a position shifted from the second program count by a value of the Length, in a second buffer, replacing the second instruction with a third instruction, which is not recognized by a microprocessor, replacing the third instruction with the second instruction stored in the second buffer when an error occurs while the third instruction is being executed, and changing the current program count of the code memory to a predetermined program count next to the first program count stored in the first buffer.
