Optimal floating point multiplication processor for signal processing

The design of a floating point matrix- vector multiplication processor array for VLSI, which has an optimal area-time complexity product, is presented. This processor array is capable of performing the function (where n = 1,…, N) and can be applied in many digital signal processing applications, by simply changing the matrix coefficients stored in that array. Each N-bit mantissa, M-bit exponent (N, M) processor element of the array comprises a mantissa multiplier/adder circuit and hardware to handle the floating point control. The multiplier/adder circuit is implemented by a new optimal algorithm, which is regular, recursive and fast. Secondly, the algorithm offers a highly local and regular interconnection network, which is a fundamental requirement in VLSI circuit design methodology.
