The LMS12 is a high-speed 12 x 12-bit combinatorial multiplier integrated with a 26-bit adder in a single 84-pin package. It is an ideal building block for the implementation of very highspeed FIR filters for video, RADAR, and other similar applications. The LMS12 implements the general form (A•B) + C. As a result, it is also useful in implementing polynomia.
are discussed individually in the following paragraphs. MULTIPLIER The A11-0 and B11-0 inputs to the LMS12 are captured at the rising edge of the clock in the 12-bit A and B input registers, respectively. These registers are independently enabled by the ENA and ENB inputs. The registered input data are then applied to a 12 x 12-bit multiplier array, which produces a 24-bit result. Both the inputs and outputs of the multiplier are in two’s complement format. The multiplication result forms the input to the 24-bit product register. SUMMER The C 25-0 inputs to the LMS12 form a 26-bit two’s comple.
