We present an optoelectronic-VLSI system that integrates complementary metal-oxide semiconductory multiple-quantum-well smart pixels for high-throughput computation and signal processing. The system uses 5 3 10 cellular smart-pixel arrays with intrachip electrical mesh interconnections and interchip optical point-to-point interconnections. Each smart pixel is a fine grain microprocessor that ex...

| This paper examines the issues and progress in the design of highly integrated microelectronic systems. These microsystems rely on an array of diverse components such as processors, memory, network interfaces, graphics and DSP `cores.' In particular, we discuss problems in the combined design of hardware and software for these systems. We present a decomposition of the co-design problem, and ...

Digital Speech Signal Processing is the process of converting one type of speech signal representation to another type of representation so as to uncover various mathematical or practical properties of the speech signal and do appropriate processing to support in solving both fundamental and deep troubles of interest. Digital Speech Processing chain has two different main model They are Speech ...

This paper presents the theoretical analysis, simulation results and suggests design in digital technology of a physical layer for wireless sensor networks.

For the proposed theoretical model of physical layer, a rigorous mathematical analysis is conducted...

In the majority of digital signal processing (DSP) applications the critical operations are the multiplication and accumulation. Real-time signal processing requires high speed and high throughput Multiplier-Accumulator (MAC) unit that consumes low power, which is always a key to achieve a high performance digital signal processing system. The purpose of this work is, design and implementation ...

This paper introduces a technique, called resynchronization, for reducing synchronization overhead in multiprocessor implementations of digital signal processing (DSP) systems. The technique applies to arbitrary collections of dedicated, programmable or configurable processors, such as combinations of programmable DSPs, ASICS, and FPGA subsystems. Thus, it is particularly well suited to the evo...

of activity in the area of CMOS image sensors has taken place. Up until recently, the dominant, and nearly the only, solid-state image sensor technology was the charge-coupled device (CCD). However, most microprocessors, logic circuits, ASICs, and memory circuits are based on CMOS technology. Now CMOS can be used for image sensors in a rapidly expanding sphere of applications. Several important...

   This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...

There is considerable interest in the development of ultra-miniature and low-power sensor microsystems for use in applications such as medical diagnostics, environmental monitoring and other industrial applications. Such ultraminiature sensor microsystems must contain a large diversity of complex electronics, including sensor interfaces, signal conditioning, a microprocessor core, digital signa...
