The host-multi-SIMD chip multiprocessor (CMP) architecture has been proved to be an efficient architecture for high performance signal processing which explores both task level parallelism by multi-core processing and data level parallelism by SIMD processors. Different from the cache-based memory subsystem in most general purpose processors, this architecture uses on-chip scratchpad memory (SPM)...
Flexible Application Specific Instruction set Processors (ASIP) are starting to replace monolithic ASICs in a wide variety of fields. However the construction of an ASIP is today associated with a substantial design effort. NoGap (Novel Generator of Micro Architecture and Processor) is a tool for ASIP designs utilizing hardware multiplexed data paths. One of the main advantages of NoGap compared to...
A low complexity hardware interleaver architecture is presented for MIMO-OFDM based wireless LAN e.g. 802.11n. Novelty of the presented architecture is twofold; 1) Flexibility to choose interleaver implementation with different modulation scheme and different size for different spatial streams in a multi antenna system, 2) Complexity to compute on the fly interleaver address is reduce by using recursion...
There is growing interest in the use of remote laboratories to access physical laboratory infrastructure. These laboratories can support additional practical components in courses, provide improved access at reduced cost, and encourage sharing of expensive resources. Effective design of remote laboratories requires attention to both the pedagogic design and the technical support, as well as how these...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
