Abstract
PURPOSE: To improve efficiency in processing when the length of an operand is long as to a translate-instruction process of an electronic computer with a virtual memory, by accelerating the processing speed of the detection of an address conversion exception through the dividing process of the translation instruction.
CONSTITUTION: During the process of an address conversion exception at the time of the translation-instruction process through an electronic computer with a virtual memory, the updates of registers and memories are inhibited; and then, translation instruction OP1, read from buffer register REG1 which holds data, is applied to one- side terminals of comparator circuits COMPs 1 to 4 via arithmetic-data input register REG2, and difference 1'x until page-cross point PC between instructions OP1 and OP2 is applied to the other-side terminals of circuits COMP1 to 4 via arithmetic input register REG3. At this time, if an input surpasses page-cross point PC, the memory access of it is attained and the detection of an address conversion exception causes an interruption; and then, the instruction is excuted after checking the contents of instruction OP1.
