Patent ID: 7610518

Claim:
A method of comparing program counter addresses comprising the steps of: storing a first reference address; comparing the first reference address with a program counter address and generating a greater than output, a less than output and an equal to output, each output depending upon the relationship between said first reference address and the program counter address; storing a second reference address; comparing the second reference address with the program counter address and generating a greater than output, a less than output and an equal to output, each output depending upon the relationship between said second reference address and the program counter address; generating a first local event signal dependent upon said greater than, said less than and said equal to output of said step of comparing the first reference address with the program counter address; generating a second local event signal dependent upon said greater than, said less than and said equal to output of said step of comparing the second reference address with the program counter address; generating a first program counter signal dependent upon said greater than, said less than and said equal to output of said step of comparing the first reference address with the program counter address and said second local event signal; and generating a second program counter signal dependent upon said greater than, said less than and said equal to output of said step of comparing the second reference address with the program counter address and said first local event signal.
