Matrix multiplication is a computation intensive operation and plays an important role in many scientific and engineering applications. For high performance applications, this operation must be realized in hardware. This paper presents a parallel architecture for the multiplication of two matrices using field programmable gate array (FPGA). The proposed architecture employs advanced design techniques...
A programming disturb mechanism in the uniform channel program and erase (UCPE) eFlash 2TC (two transistor cell) is investigated. High GIDL current from the SG (selected gate) on the selected row and unselected columns introduce additional gate disturbs in a high density eFlash product. It is observed that the 1TC eFlash without an SG configuration did not show the same mechanism. When the SG bias...
Development of analog electronics solutions for space avionics is expensive and time-consuming. Lack of flexible analog devices, counterparts to digital Field Programmable Gate Arrays (FPGA), prevents analog designers from the benefits of rapid prototyping. This forces them to expensive and lengthy custom design, fabrication, and qualification of application specific integrated circuits (ASIC). The...
Digital correlation techniques are used in photon correlation spectroscopy (PCS) experiments to gain information about the diffusion coefficient and thereby the size and distribution of submicron particle structures in fluid media. This paper presents a photon correlation system implemented by high performance FPGA (Field Programmable Gate Array). Owning to the digital nature of photon counting, correlators...
To increase gate density, a dynamic optically reconfigurable gate array (DORGA) architecture has been proposed that uses the junction capacitance of photodiodes as dynamic memory, thereby obviating the static configuration memory. To date, estimation of the DORGA architecture using a liquid crystal holographic memory has been conducted, thereby demonstrating its availability. However, because the...
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...
H.264/AVC is a new international standard for the compression of natural video images, in which deblocking filter has been adopted to remove blocking artifacts. The deblocking filter is either time or area consuming system component. The goal of this paper is a design of area-time efficient H.264/AVC deblocking filter suitable for application in mobile devices. Area-time tradeoff is enabled by using...
