Latest Patents
Among his latest patents is an innovative apparatus and method for generating a packed sum of absolute differences. This method involves executing an MMX PSADBW instruction by a microprocessor. The process includes generating packed differences of operands and determining the associated borrow bits. The method selects values based on whether the borrow bit indicates a positive or negative packed difference. This results in generating a first sum and a first carry, which are then combined with the borrow bits to produce the final result stored in a register of the microprocessor.
Another significant patent by Johnson is a microprocessor designed for generating a packed sum of absolute differences. This microprocessor features an instruction translator that converts a Multimedia Extensions (MMX) Packed Sum of Absolute Differences Byte to Word (PSADBW) macroinstruction into microinstructions. The MMX unit within the microprocessor generates the result of the PSADBW macroinstruction based on these microinstructions.
