The multiplier device which uses all the adding machine modules and the said all the adding machine modules

摘要

All the adding machine modules (30), it has the plural input and output terminal and all adding machine which has with harmony occurrence unit and carrying occurrence unit. Carrying occurrence unit responding to the control signal which is supplied to one of the aforementioned plural input terminals, the carrying input bit to particular carrying occurrence unit has the programmable invertor which reverses selectively. These all the adding machine modules (30), the logical block where the area efficiency which supports mark equipped multiplication is good is offered, this logical block maintains the programmable characteristic, it is possible to execute the other all operation which is made purpose.
