The main issue of this paper is the studies on the free-space optical interconnection (FSOI) technology and the correlative physical layout algorithm for computer generated hologram (CGH) in optoelectronic multi chip module (OEMCM) systems design. A new effective physical layout algorithm is also presented. The computer simulation results show that our algorithm is useful in dealing with the restricted space-position problems that occurred in massively interconnection networks. And the comparison of placement layout results between our new algorithm and several other algorithms indicates an advance.

In this paper, a pipeline Reed-Solomon decoder based on time domain decoding technique is presented. High throughput is achieved by parallel computation in the modified Euclid algorithm block, and the complex control circuit is simplified by a switch box strategy. In addition, the constant finite field multiplier is optimized to reduce the chip area, thus make the decoder suitable for HDTV.

In this paper, a new architecture of configurable analog unit based on switch capacitor technology is presented. The architecture consists of four parts of input expansion, SC building block, self-calibrating OpAmp and clock control. The architecture not only achieves linear analog application such as integrator, gain amplifier, filter, etc., but also can be expediently configured to implementing some nonlinear analog applications. A programming mechanism using two programmable selector for parameter selector and function selector are illustrated for the architecture. The architecture is propitious to utilize configuration and technology mapping. As nonlinear analog application, a voltage control oscillator is implemented. Simulation result with HSPICE shows that for 0.6μ CMOS process, the relative error of voltage-frequency is less than 0.2%.

In this paper, we present Frequency domain Fast Wavelet Collocation Method (FFWCM) for high-speed circuit simulation. Compared with the Time domain Fast Wavelet Collocation Method (TFWCM), FFWCM presents the following merits. First, it consumes much less memory space and computation time, and can effectively deal with large scale circuits. Second, the frequency domain singularity can be easily handled by adaptive scheme and a frequency domain uniform error distribution can be achieved. Furthermore, the approximated time domain analytical solution can be simply obtained without performing the time consuming numeric inverse Laplace transforms. Numerical experimental results have further demonstrated the promising features of FFWCM.

A novel VLSI design and implementation of a low power 8-bit microcontroller using asynchronous logic is proposed in this paper. Taking advantage of the low power potential of asynchronous logic, the 2-stage pipeline MCU is carefully designed by chosen proper architecture as well as suitable asynchronous signal protocols which including a combination of a specific "Completion Detection Method" and "matching delay Method". Other low power design techniques such as "Gating Clock"also applied to the design. Using synchronous design flow and standard-cell library facilitates the VLSI design and circuit implementation. Fabricated in Chartered 0.6um CMOS technology, this low power asynchronous MCU achieves only 16% power dissipation of the conventional designed PIC16C61, which shares the same instruction set and function as the MCU we designed.
