ABSTRACT:
A diagonal propagation, digital multiplier of a kind adapted to multiply a first factor by a second factor, with the factors each being expressed as a binary number including a non-volatile memory having a plurality of cells each with one digit of a factor stored therein, a plurality of computation blocks cascade connected together, each block being also connected to a corresponding cell in the memory, computation stage in each of the blocks for performing a binary sum of the first factor plus one digit of the second factor, and memory elements in each of the blocks for storing therein the result of the calculation and making it available as a pseudo-carryover to the next block.
