As the number of potential applications for tiny, battery-powered, “mote”-like, deeply embedded devices grows, so does the need to simplify and secure interactions with such devices. Embedding a secure web server (capable of HTTP over SSL, aka HTTPS), enables these devices to be monitored and controlled securely via a user-friendly, browser-based interface. This paper presents the first empiric...

Dynamic compilation techniques have found a renaissance in recent years due to their use in high-performance implementations of the JavaTM language. Techniques originally developed for use in virtual machines for such object-oriented languages as Smalltalk are now commonly used in Java virtual machines (JVMTM) and Java just-intime compilers. These techniques have also been applied to binary tra...

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...

We present a lock-free implementation of a dynamically sized double-ended queue (deque) that is based on the double compare-and-swap (DCAS) instruction. This implementation improves over the best previous one by allowing storage to be allocated and freed in bulk when the size of the deque changes significantly, and to avoid invocation of the storage allocator at all while the size remains relat...

Access to persistent data is a requirement for the majority of computer applications. The Java programming language and associated run-time environment provide excellent features for the construction of reliable and robust applications, but currently these do not extend to the domain of persistent data. Many mechanisms for managing persistent data have been proposed, some of which are now inclu...

The JavaTM platform has a stigma of being a poor performer and has often been shunned as an environment for developing speech engines. We decided to better understand this stigma by writing a speech synthesis engine entirely in the Java programming language. Remarkably, we were able to get better performance from our engine than one using similar algorithms written in C. Our team, composed of t...
