METHOD AND SYSTEM FOR BLOCKING PROCESSING/FILTERING RESTRICTION OF COMPUTER ENVIRONMENT BASED ON ADDRESS

摘要

PURPOSE: A method and a system for blocking processing/filtering restriction of a computer environment based on an address are provided to promote processing of the computer environment by filtering/blocking the processing restriction in order to continue the processing in spite of the restriction when a processing unit of the computer environment is encountered with the processing restriction. CONSTITUTION: A control part(200) is connected to multiple CPUs(201). The CPU includes a cache control(212), an interrupt control(220), and an execution control(222). In response to a specified event, the interrupt control makes an internal interruption stay in the CPU and the CPU makes the execution control sequentially stop program instruction processing at the next interruptible time point. In response to the interruption, the execution control makes the cache control process the stayed instruction by making an approved internal code routine fix a latch(224) that a broadcasting operation is allowed.
