Abstract
A simplified comparison of register designations by using a window delta which indicates how much the window of an instruction differs from the current window register designation. Where registers are shared, the windows will either be the same or differ by one. Thus, a single bit can be used to indicate the window delta, and in combination with the logical register address, can be used to quickly determine whether there is a register match between instructions.
