Ethernet Subsystem Verification : A Review

Reusable Verification Environment for Verification of Ethernet

Design reuse and verification reuse are important to satisfy time to-market requirements. Designer must be able to reuse Intellectual Property in the design as golden model. Reuse of verification environment across different designs of the domain saves time to market further and improves total design verification quality. The Physical Layer is a fundamental layer upon which all higher level fun...

Directed Point: a communication subsystem for commodity supercomputing with Gigabit Ethernet

High Performance Communication Subsystem for Clustering Standard High- Volume Servers Using Gigabit Ethernet

This paper presents an efficient communication subsystem, DP-II, for clustering standard high-volume (SHV) servers using Gigabit Ethernet. The DP-II employs several light-weight messaging mechanisms to achieve low-latency and high-bandwidth communication. The test shows an 18.32 us single-trip latency and 72.8 MB/s bandwidth on a Gigabit Ethernet network for connecting two Dell PowerEdge 6300 Q...

Average entropy of a subsystem.

If a quantum system of Hilbert space dimension mn is in a random pure state, the average entropy of a subsystem of dimension m ≤ n is conjectured to be S m,n = mn k=n+1 1 k − m−1 2n and is shown to be ≃ ln m − m 2n for 1 ≪ m ≤ n. Thus there is less than one-half unit of information, on average, in the smaller subsystem of a total system in a random pure state.
