Virtual memory concept has been used for a long time in computer systems. Memory Management Unit (MMU) in microprocessor is an essential part of the application of VM concept. As part of modern MMU designs, small but fast cache memory for address mappings called Translation Lookaside Buffer (TLB) is often utilized. TLB is crucial for MMU performance. It can be completely realized in hardware or combine...
This paper proposes a QC-LDPC partial parallel architecture that implements a hard decision message passing algorithm based on Gallager-B decoding. The proposed architecture uses an optimized variable node unit, with adaptive threshold, suitable for irregular LDPC codes. We present implementation results for WiMAX rate 1/2 code for FPGA technology. These indicate a cost reduction of 2.5x in logic,...

Astract — This paper describes one solution for an implementation of the surround speaker virtualization module for digital signal processor in sound bar systems. The main problem in sound bar systems is complex audio processing execution in real-time. When the virtualization algorithm is executed on the embedded platform in real-time, it produces surround sound from the sound bar placed in front...
