Abstract
A semiconductor device according to one includes: an initial value setting unit configured to provide an initial value of a register that holds a cumulative value to be a result of a product-sum operation in a product-sum operation circuit; and an initial value canceling circuit configured to cancel the initial value contained in the cumulative value held by the register and output a final output value, and the initial value setting unit sets a positive or negative value other than zero as the initial value.
Claims11
A semiconductor device comprising:
- a multiplier configured to calculate a product of first data and second data whose values change for each processing cycle;
- a register configured to hold a value obtained by updating a cumulative value of output values of the multiplier for each processing cycle and output it as a register value;
- an adder configured to add the output value of the multiplier and the register value to update the cumulative value;
- an initial value setting unit configured to provide an initial value of the register value;
- and
- an initial value canceling circuit configured to cancel the initial value contained in the register value and output a final output value,
- wherein the initial value setting unit sets a positive or negative value other than zero as the initial value.
