In this paper, we present a data puncturing (DP) type-II hybrid ARQ protocol with Low-Density ParityCheck (LDPC) codes. Incremental redundancy is created from punctured versions of the original data using the same encoder/decoder hardware. This way, parts of the initially received data can be gradually improved until successful decoding of the entire code(More)
The clock tree is the interconnect net on Systems-on-Chip (SoCs) with the heaviest load and consumes up to 40% of the overall power budget. Substantial savings of the overall power dissipations are possible by optimizing the clock tree. Although these savings are already relevant at system-level, only little effort has been made to consider the clock tree(More)
In this paper, we present a low-complexity soft detection and soft decoding magnetic disk drive read channel with a modified soft output signal space detector (SD) which uses 3D-110 equalization and an error/erasure decoding Reed Solomon (RS) code. The detector determines Max-Log reliability information for intersymbol interference (ISI) channels with(More)
