Patent DE-4223999-C1 (DE)
Title: Digital multiplication circuit using canonically signed digit code - has multiplexer converted and added to two's-complement value to generate reduced partial products that are added
IPC: G06F7/52
Filed: 1992-07-21
Granted: 1993-07-08
Abstract: The digital circuit has the multiplier represented in canonically signed digit (CSD) form and the multiplicand in 2's complement form. A particular feature of the CSD code is that each second line of the multiplication structure is zero. This halves the number of additions of partial products necessary to obtain a result. The circuit has a converter (3) for CSD code. The converter output is received by a stage (4) which adds a corrective digit and a partial product stage (2). The sign or most significant bit is handled by a switching stage (6). USE/ADVANTAGE - for multiplication of two binary numbers used with filter, signal processor, microprocessor or correlator. Reduces amount of hardware and delay time.
