Title:
INTERRUPTION MANAGING METHOD FOR MICROPROCESSOR SYSTEM
Document Type and Number:
Japanese Patent JP3209560
Kind Code:
B2
Abstract:
PURPOSE: To provide the interruption managing method for generating easily an interruption handler, and decreasing an overhead of an OS.
CONSTITUTION: In the microprocessor system for suspending a processing at the time when a CPU 1 which is executing a processing through an OS 10, receives an interruption request from an external device, and allowing an interruption handler 31 to execute an interruption processing, this system is constituted by providing a double interruption designating means 20 for designating a soft interruption at the time when it is actuated from the CPU which receives the interruption request and migrating the processing to the OS before migrating the processing to the interruption handler, an interruption handler actuation processing means 11 for analyzing an interruption factor and retaining a register, etc., in the OS and actuating the interruption handler, and an interruption handler finish-processing means 12 for executing reset of the register, etc., and an interruption finish processing to the external device in the OS at the time when an end of the interruption processing is informed from the interruption handler, and thereafter, restarting the suspended processing.
