US Patent 7436688 Priority encoder circuit and method

A priority encoder circuit can include a number of sectional encoder circuits that each encode “m” inputs signals into sets of “P” encoder outputs, where m>p. Each sectional encoder circuit can also output a group indication signal representing the activation of any of the received m encoding input signals. Priority encoder logic can prioritized the group indication signals. A memory can include a different storage location accessed by each prioritized group indication signal.
