Title: Brendan Walsh - Innovator in Arithmetic Logic Units
Introduction
Brendan Walsh is a notable inventor based in Bedford, GB. He has made significant contributions to the field of arithmetic logic units, holding a total of 5 patents. His work primarily focuses on the development of advanced logic circuits that enhance computational efficiency.
Latest Patents
One of his latest patents is a three input arithmetic logic unit that forms a mixed arithmetic and Boolean combination of three multibit input signals. This innovative unit first creates a Boolean combination and then an arithmetic combination. The current instruction drives an instruction decoder that generates function signals F0-F7, which control the combination formed. The design employs a set of bit circuits that generate carry propagate, generate, and kill signals. These signals, along with a carry input, produce a bit resultant and a carry output to the next bit circuit. The selection of function signals allows the combination to be insensitive to one of the input signals, effectively performing a two-input function of the remaining signals. The instruction may include function signals and modification bits, or these may be stored in a special data register. Function modification signals can alter the function signals before use. Additionally, the unit includes a least significant bit carry-in generator that supplies a carry input to the least significant bit circuit, which is typically '1' only during subtraction.
