amount of computational power to researchers at an affordable cost, making it feasible to use workstations rather than expensive supercomputers to perform scientific analysis of large data sets, such as the Global Land 1-Km AVHRR data. In addition to this, inexpensive high speed ATM networks have the potential to improve the overall computational efficiency of workstations by using several workstations in a distributed environment. This research studies the practicality of using distributed workstations interconnected with a 155 Mb ATM network for analysis and compression of the Global Land 1-Km AVHRR data versus sequential computing on one of the workstations. Performance …


Synthesis For Testability By Two-Clock Control, Shashank K. Mehta, Sharad C. Seth, Kent L. Einspahr Jan 1997

Synthesis For Testability By Two-Clock Control, Shashank K. Mehta, Sharad C. Seth, Kent L. Einspahr

CSE Conference and Workshop Papers

In previous studies clock control has been inserted after design to improve the testability of a sequential circuit. In this paper we propose a two-clock control scheme that is included as a part of the logic synthesis of a finite state machine (fsm). The scheme has low area overhead and competes well with scan methods in its ability to initialize and observe circuit states. The states of the machine are assigned a pair of binary values using a novel split coding system. The purpose of the encoding is to ease navigation between any pair of states using a combination of …


Minimizing The Number Of Optical Amplifiers Needed To Support A Multi-Wavelength Optical Lan/Man, Byrav Ramamurthy, Jason Iness, Biswanath Mukherjee Jan 1997

Minimizing The Number Of Optical Amplifiers Needed To Support A Multi-Wavelength Optical Lan/Man, Byrav Ramamurthy, Jason Iness, Biswanath Mukherjee

CSE Conference and Workshop Papers

Optical networks based on passive star couplers and employing wavelength-division multiplexing (WDhf) have been proposed for deployment in local and metropolitan areas. Amplifiers are required in such networks to compensate for the power losses due to splitting and attenuation. However, an optical amplifier has constraints on the maximum gain and the maximum output power it can supply; thus optical amplifier placement becomes a challenging problem. The general problem of minimizing the total amplifier count, subject to the device constraints, is a mixed-integer non-linear problem. Previous studies have attacked the amplifier placement problem by adding the “artificial” constraint that all wavelengths, …
