HIGH PRECISION DECOMPOSABLE DSP ENTITY

Abstract:

A digital signal processing (DSP) block includes a plurality of multipliers and a summation block separate from the plurality of multipliers. The DSP block is configurable to perform a first multiplication operation to determine a first product of a first floating-point value and a second floating-point value using only a first multiplier of the plurality of multipliers. Additionally, the DSP block is configurable to perform a second multiplication operation between a third floating-point value and a fourth floating-point value by receiving, at each of the plurality of multipliers, two integer values generated from the third floating-point value and the fourth floating-point value, generating, via the plurality of multipliers, a plurality of subproducts by multiplying, at each of the multipliers, the two integer values, and generating a second product of the second multiplication operation by adding, via the summation block, the plurality of subproducts.
