Abstract

In order to achieve fast decoding and improve the throughput, this paper uses the polar code to encode the spin transfer torque MARAM (STT-MRAM) channel. Based on the Fast-SSC algorithm, a (256, 220) hardware architecture is designed, including the controller, processing element, Kronecker product and memory module. This paper reduces the complexity of data process by splitting the data of nodes, and reduces the memory bandwidth by increasing the reusability of data. The decoder is synthesized on Stratix V 5SGXEA7N2F45C2, the decoding latency is 0.68us, and it can achieve 375 Mbps at 167 MHz.
