A Stream-based Reconfigurable Router Prototype

Implementation and Evaluation of a Prototype Reconfigurable Router

The evolution of computer networking technology will likely require hardware that is flexible enough to adapt to changing standards while maintaining the highest possible performance. Much research has recently been done in active networks, which increase network flexibility by allowing the routers to be reprogrammed, often at the cost of lower throughput. A reconfigurable router implemented on...

CMOS Bit-Stream Band-Pass Beamforming

We introduce a unique bandpass ΣΔ based common module with reconfigurable, bit-stream based digital beam-forming (DBF). An array of bandpass ΣΔ modulators accurately and efficiently digitizes the IF signals. Beam-forming is implemented directly through bitsteam processing of the fast, low-resolution bit-stream outputs of the quantizers of each bandpass ΣΔ modulator. Fabricated in 65nm CMOS, the...

Highly Efficient Reconfigurable Routers in NoCs

NoC designs are based on a compromise of latency, power dissipation or energy, usually defined at design time. However, setting all parameters at design time can cause either excessive power dissipation (originated by router underutilization), or a higher latency. The situation worsens whenever the application changes its communication pattern, i.e., a portable phone downloads a new service. Th...

SmartCell: An Energy Efficient Coarse-Grained Reconfigurable Architecture for Stream-Based Applications

This paper presents SmartCell, a novel coarse-grained reconfigurable architecture, which tiles a large number of processor elements with reconfigurable interconnection fabrics on a single chip. SmartCell is able to provide high performance and energy efficient processing for stream-based applications. It can be configured to operate in various modes, such as SIMD, MIMD, and systolic array. This...
