Hardware Barrier Synchronization: Static Barrier Mimd (Sbm), Matthew T. O'Keefe, Henry G. Dietz Jan 1990

Hardware Barrier Synchronization: Static Barrier Mimd (Sbm), Matthew T. O'Keefe, Henry G. Dietz

Department of Electrical and Computer Engineering Technical Reports

In this paper, we give the design, and performance analysis, of a new, highly efficient, synchronization mechanism called “Static Barrier MIMD” or “SBM.” Unlike traditional barrier synchronization, the proposed barriers are designed to facilitate the use of static (compile-time) code scheduling for eliminating some synchronizations. For this reason, our barrier hardware is more general than most hardware barrier mechanisms, allowing any subset of the processors to participate in each barrier. Since code scheduling typically operates on fine-grain parallelism, it is also vital that barriers be able to execute in a small number of clock ticks. The SBM is actually only …


Surface Passivation Effects Of As2s3 Glass On Self‐Aligned Algaas/Gaas Heterojunction Bipolar Transistors, H. L. Chuang, M. S. Carpenter, Michael R. Melloch, Mark S. Lundstrom, E. Yablonovitch, T. J. Gmitter Jan 1990

Surface Passivation Effects Of As2s3 Glass On Self‐Aligned Algaas/Gaas Heterojunction Bipolar Transistors, H. L. Chuang, M. S. Carpenter, Michael R. Melloch, Mark S. Lundstrom, E. Yablonovitch, T. J. Gmitter

Department of Electrical and Computer Engineering Faculty Publications

A recently developed As2S3 chemical treatment was used to passivate the perimeters of self‐aligned heterojunction bipolar transistors (HBTs). The As2S3chemical treatment significantly lowered the base current resulting in a two order of magnitude reduction in the collector current density at which dc current gain was observed (β=1). No degradation with time has been observed in the electrical characteristics of the chemically treated HBTs. This absence of degradation is attributed to the impermeability to oxygen of the As2S3 glass which coats the perimeter of the HBT after chemical treatment.

Optimal Code Scheduling For Multiple-Pipeline Processors, Ashar Nisar, Henry G. Dietz Jan 1990

Optimal Code Scheduling For Multiple-Pipeline Processors, Ashar Nisar, Henry G. Dietz

Department of Electrical and Computer Engineering Technical Reports

Pipelining the functional units and memory interface of processors can result in shorter cycle times and dramatic increases in performance, but only if the pipeline latency can be hidden by other useful operations. The portion of pipeline latency which is not hidden results in an extension of the total execution time, either implemented by hardware interlocks or by compile-time insertion of NOPs (Null Operations). By rearranging instructions, it is possible to minimize the total pipelined execution time, but the problem of finding this optimal code schedule is well known to be NP-complete. In this paper, we describe a code scheduler …
