The majority of recent Java implementations have been focused on speed. There are, however, a large number of consumer and industrial devices and embedded systems that would benefit from a small Java implementation supporting the full bytecode set and dynamic class loading. In this report we describe the design and implementation of the Spotless system, which is based on a new Java virtual mach...

Modern high-performance virtual machines use dynamic compilation. There is a tension between compilation speed and code quality. We argue that a highly-optimizing compiler is best deployed with both a fast, less-optimizing compiler and an interpreter. We present measurements showing that such a system can achieve the same peak performance as a system with just the optimizing compiler, and start...

Annotations are often added to mobile code to reduce the optimization burden of just-intime compilers. However, these annotations are not checked for correctness and must be trusted—incorrect or malicious annotations could lead to the generation of incorrect or insecure code. We present a timeand space efficient method for verifying the results of the large class of data flow optimizations. Thi...

This paper reviews the engineering solutions and economic models for fair allocation of network bandwidth to elastic flows. By using examples, it gives insight to Proportional Fairness, and how it compares to the fairness achieved by TCP. The second topic is a discussion of fair bandwidth allocation between multicast and unicast flows. By separating the discussion into economic and engineering ...

the main purpose of trademark legal system is protection of trademarkagainst any unauthorized use, so today many of existing legal systems haveprovide different enforcements for breach of trademark. well knowntrademarks have always been considered as a valuable property bylegislatures and protected as a particular category of trademarks. oncontrary to infringement, dilution doctrine, which is a...

Many garbage-collected systems, including most that involve a stop-the-world phase, restrict GC to socalled GC points. In single-threaded environments, GC points carry no overhead: when a GC must be done, the single thread is already at a GC point. In multi-threaded environments, however, only the thread that triggers the GC by failing an allocation will be at a GC point. Other threads must be ...

Designing a modern microprocessor is a complex task that demands careful balance between cycle time, cycles-per-instruction, and area costs. In particular, the instruction fetch unit greatly affects the performance of a multi-issue processor. It must provide adequate bandwidth to sustain peak instruction issue rate, and must predict future instruction sequences with high accuracy. In the UltraS...
