Abstract
PURPOSE: To increase the efficiency for a series of processes, by supplying the element of the vector register into the 1st arithmetic process part and writing the mask bit generated at the 1st airthmetic process part as well as supplying the mask bit to the 2nd arithmetic process part.
CONSTITUTION: For the COMPARE instruction, the elements are read sequentially out of vector register 5 which is designated by the 2nd and 3rd operand parts of the instruction to be supplied to adder 9. The mask bit produced at adder 9 is sent to mask register 6 designated by the instruction to be written there. This mask bit is then read and then set to reading register 8 in the next timing. With this timing the elements to be sent to multiplier 10 are set to register 8. After this, both the COMPARE instruction and the MULTIPLY instruction are executed simultaneously. The result of multiplication delivered from multiplier 10 is sent to writing register 3 along with the corresponding mask bit. In this case, the result of multiplication having the mask bit of 1 is not written into vector register 5.
