  • Method for computing a difference in a digital processing system
    Patent number: 6014738
    Abstract: According to a presently preferred embodiment of the present invention, a method for processing a incoming signal comprising the steps of selecting from a first signal a first plurality of bits of signal information to be processed, selecting from a second signal a second plurality of bits of signal information to be processed, reading the first plurality of bits of signal information into contiguous memory space so as to form a first word, reading the second plurality of bits of signal information into contiguous memory space so as to form a second word, causing a first logical AND operation to be performed on the second word with a mask, causing a first logical OR operation between the first word and the complement of the mask, causing a first EXCLUSIVE OR operation between the first word and the complement of the second word, causing a second logical AND operation between the results of the first EXCLUSIVE OR operation and the complement of the mask, subtracting the results of the first logical AND operati
    Type: Grant

  • Method for forming a sum in a signal processing system
    Patent number: 5912677
    Abstract: According to a presently preferred embodiment of the present invention, a method for processing a incoming signal comprising the steps of selecting a first set of bits of digital information from a first signal, selecting a second set of bits of digital information from a second signal, reading the first set of bits of signal information into a first contiguous memory space to form a first word, and then reading the second set of bits of signal information into a second contiguous memory space to forming a second word, performing a first EXCLUSIVE OR operation on the first word with the second word, performing a first logical AND operation on the first word with a mask, performing a second logical AND operation of said second word with a mask, performing a first addition operation of the results of the first logical AND operation with the results of the second logical AND operation, performing a third logical AND operation on the results of the first EXCLUSIVE OR operation with a mask word, and then performin
