CONTENTION-FREE PARALLEL PROCESSING MULTIMODE LOW-DENSITY-PARITY-CHECK DECODER, CAPABLE OF DECODING ENCODED TRANSMITTED DATA

摘要

PURPOSE: A contention-free parallel processing multimode low-density-parity-check(LDPC) decoder is provided to prevent the collision of memories by sharing the memories in the multimode LDPC decoder.;CONSTITUTION: An LDPC context-based operation reconfigurable instruction set processors(CRISP)(300) comprises an instruction decoder-address generator block(305). The instruction decoder-address generator block is a programmable finite-state machine. The instruction decoder-address generator block functions as a controller which controls the LDPC CRISP and the components of the LDPC CRISP. The LDPC CRISP comprises an input buffer(310), a read switch(315), a processor array(320), a write switch(325), and an external buffer(330).;COPYRIGHT KIPO 2010
