In this paper we introduce <i>Chisel</i>, a new hardware construction language that supports advanced hardware design using highly parameterized generators and layered domain-specific hardware languages. By embedding Chisel in the Scala programming language, we raise the level of hardware design abstraction by providing concepts including object(More)
Several research groups are implementing analog integrated circuit models of biological auditory processing. The outputs of these circuit models have taken several forms, including video format for monitor display, simple scanned output for oscilloscope display, and parallel analog outputs suitable for data-acquisition systems. Here, an alternative output(More)
In this paper, we present a relatively primitive execution model for ne-grain par-allelism, in which all synchronization, scheduling, and storage management is explicit and under compiler control. This is dened by a threaded abstract machine (TAM) with a multilevel scheduling hierarchy. Considerable temporal locality of logically related threads is(More)
We are developing a set of reusable design blocks and several prototype systems for emulation of multi-core architectures in FPGAs. RAMP Blue is the first of these prototypes and was designed to emulate a distributed-memory message-passing architecture. The system consists of 768-1008 MicroBlaze cores in 64-84 Virtex-II Pro 70 FPGAs on 16-21 BEE2 boards,(More)
