Abstract

Volume holographic storage is currently the subject of widespread interest as a fast data readout, high-capacity digital data-storage technology. However, due to the effect of cross-talk noise, scattering noise, noise gratings formed during a multiple exposure schedule, it brings a lot of burst errors and random errors in the system. In general, row and column (RAC) array codes is based on single parity check codes, so it is weak to correct errors ability. In order to get the acceptable bit error rate (BER)(10^-12). This paper presents multiblock strategy to solve the application of involving an entire page of data which may be as large as 1Mbits and We design VLSI implementations of multiblock RAC array coding encoder and decoder architecture for volume holographic storage. We analyze performance about hardware requirements and time delays associated with the multiblock RAC array code.
