PURPOSE:To increase execution speed of a program by suppressing the frequency of data transfer between a main storage device and register blocks in a computer system. CONSTITUTION:Data transfer control part 12 is informed of the generation of interruption via line 15 to perform prescribed processing. In the restart of a program after the interruption, control part 12 reads the contents of block RB in register block group 1 having a number, given to line 13, from save region S in corresponding main storage device 2 and returns it to corresponding block RB, and at the same time, the contents of save indicating register SLR3 are decreased by one via line 4. Every time the contents of block-number specifying register ALR7 are decreased, whether the contents of RB to be used next are saved in region S or not is inverstigated by referring to SLR3 and when so, data in corresponding region S is listed in RB while the contents of SLR3 are decreased by one. |
