Based on the modified Booth's algorithm, a fast 1-D serial- parallel systolic multiplier is designed for multiplying two's complement numbers. The circuit with countercurrent data flow pattern accepts the multiplicand serially, the multiplier in parallel, and outputs the product serially. It requir...
Each multiplexer includes I and Q summed outputs based on the value of I and Q reference data on a bit-by-bit basis. An n bit Wallace Tree Adder is connected to each of the I and Q summed outputs for each multiplexer within each of the n parallel paths and computes a count based ...
along to the ALU 110 which adds them and passes the resultant effective address to the SR/C 90. SR/C 90 may then be incremented, under either global or local control, in order to access multiple bit words through the address multiplexer 95. Each is bit stored sequentially in the memory ...

the number of registers would be adjusted accordingly. Note in FIG. 4A that each I/Q pair of VGAs150A,150B is set to the same gain. The gain for each pair is set using a multiplexer (MUX)440which selects one of three values stored in the VGA storage registers435via the BAND_SEL ...
