Patent ID: 7975194

Claim:
A system, comprising: a decompressor configured to receive an input test vector and to generate an output vector in response to the input test vector; a decoder coupled to the decompressor and comprising a reset pattern detector, a lookup table, and control logic; wherein the reset pattern detector (RPD) is configured to scan the output vector to identify a predetermined reset pattern; wherein the control logic couples to the RPD and the lookup table and is configured to direct operation of the lookup table in a first mode or a second mode based on whether the output vector comprises the predetermined reset pattern, as identified by the RPD; and wherein the lookup table is configured: to receive the output vector; to operate in the first mode, comprising storing one of a plurality of codeword sets, each codeword set comprising a plurality of pairs of codewords and associated data; and to operate in the second mode, comprising generating test data blocks in response to identified codewords in the output vector.
