Presented here are latest advances in ultra short pulse laser based parallel processing using a spatial light modulator (SLM), which has the potential for use in high throughput precision patterning of photovoltaic and other device layers. Ultra short laser pulses allow selective material removal with minimal energy density, while here a computer- generated hologram driven reflective SLM is used to...
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)...
The host-SIMD style heterogeneous multi-processor architecture offers high computing performance and user friendly programmability. It explores both task level parallelism and data level parallelism by the on-chip multiple SIMD coprocessors. For embedded DSP applications with predictable computing feature, this architecture can be further optimized for performance, implementation cost and power consumption...
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...
