The first single-chip superconductor FLUX-1 microprocessor has been designed in the Rapid Single Flux Quantum (RSFQ) logic and fabricated using 4 kA/cm, 1.75μm Nb/AlOx/Nb Josephson junction technology as a result of the collaboration between SUNY Stony Brook and TRW, Inc. A FLUX-1 chip represents an 8-bit deeply pipelined microprocessor prototype with a target clock frequency of 17-20 GHz. A ne...

The microelectronics industry is pursuing many options to sustain the performance improvement expected every two years. One method for performance improvement is scaling transistor sizes down such that many more transistors can be compacted on chip. The on-chip temperature is a concern because the reliability and performance can be degraded due to hot spots. Thermal modeling of the chip will al...

Microprocessor packaging is undergoing major changes driven by technical, business, and economic factors. From the traditional role of a protective mechanical enclosure, the modern microprocessor package has been transformed into a sophisticated thermal and electrical management platform. Furthermore, microprocessor architecture and design techniques can have significant impact on the complexit...

In the recent years, Xilinx devices, like the XC6200, were the preferred solutions for evolving digital systems. In this paper, we present a new System-On-Chip, the POEtic chip, an alternative for evolvable hardware. This chip has been specifically designed to ease the implementation of bio-inspired systems. It is composed of a microprocessor, and a programmable part, containing basic elements,...

In this paper we present a portable battery-operated 3D magnetic microsystem (magnetodosimeter), intended for monitoring the workers' exposure to magnetic fields, in particular, working environments such as hospitals or physics laboratories. The proposed microsystem is based on a multi-chip module containing three equal channels for the three components of the magnetic field measurement, a micr...

Portable, embedded systems place ever-increasing demands on high-performance, low-power microprocessor design. Dynamic voltage and frequency scaling (DVFS) is a wellknown technique to reduce energy in portable systems, but DVFS effectiveness suffers from the fact that voltage transitions occur on the order of tens of microseconds. Voltage regulators that are integrated on the same chip as the m...

This paper investigates various approaches to embed the functionality of in-circuit emulation (ICE) into microprocessor cores in SoC (System-On-Chip) chips. Three styles of ICE’s (hardware-oriented, software-oriented and hybrid) are defined and implemented. They are integrated with a synthesizable ARM7 microprocessor core and synthesized to gate level to quantitatively analyze and compare their...

The System-on-Programmable-Chip (SoPC) architecture to implement a stereo matching algorithm based on the sum of absolute differences (SAD) in a FPGA chip is proposed. The hardware implementation involves a 32-bit Nios II microprocessor, memory interfaces and stereo matching algorithm circuit module. The Nios II microprocessor is a configurable soft IP core in charge of managing the buffer of t...

In today’s world speed is one of the important factor that is considered for selecting any electronic component in the market. Speed of a microprocessor based system mainly depends on the speed of the microprocessor which in turn depends on the memory access time. cache compression is one of the way to increase speed of a microprocessor based system since it increases cache capacity and off-chi...
