This paper describes the implementation of AXI compliant DDR3 memory controller. It discusses the overall architecture of the DDR3 controller along with the detailed design and operation of its individual sub blocks, the pipelining implemented in the design to increase the design throughput. It also discusses the advantage of DDR3 memories over DDR2(More)
We present the design and implementation of a phase luminometry sensor system with improved and tunable detection sensitivity achieved using a complementary metal-oxide semiconductor (CMOS) integrated circuit. We use sol-gel derived xerogel thin films as an immobilization media to house oxygen (O2) responsive luminescent molecules. The sensor operates on(More)
This paper presents the design and development of a Geochemical Expert System prototype (GES) for analyzing solution-mineral interactions in nature. The emphasis is placed on expert system design and knowledge representation. One of the most challenging and research-intensive steps was the identification of the key geochemical characteristics that would(More)
Orthogonal frequency division multiplexing (OFDM) has several properties which make it an attractive modulation scheme for high speed wireless transmission links. In this paper, a novel power sharing technique is proposed for different users to improve the system performance. The proposed technique is based on use of variable amplitude of subcarriers (VAS).(More)
