Abstract:
1. An apparatus for interrogating a data frame, the data frame comprising a plurality of bits, the apparatus comprising: first logic, the first logic being configured to select a particular bit pattern in the data frame for interrogation; second logic, the second logic being configured to compare a selected bit comparison value to said bit pattern to produce a comparison result, wherein the second logic is reconfigurable to enable said bit comparison value to be altered; third logic, the third logic being configured to determine a location to which the comparison result is to be routed, and wherein one of said first, second and third logic is reconfigurable; fourth logic, the fourth logic being configured to resolve said comparison result into a first single digital value and to output the first single digital value to the third logic for routing by the third logic; and complex comparison logic, the complex comparison logic being configured to compare the first single digital value from the fourth logic to a second single digital value to produce a complex comparison result.
