StReAm: object-oriented programming of stream architectures using PAM-Blox

General-purpose microprocessors are designed to deliver low-latency computation with maximal clock frequencies, leading to high power consumption. In terms of performance and power consumption, latency-tolerant applications can be efficiently implemented with architectures that provide high throughputs, such as Imagine, Score, RaPiD, and the PCI-PipeRench. Stream architectures are fully-pipelined, high-throughput microarchitectures. Algorithms are executed by mapping dataflow graphs to hardware and streaming the data through the architecture. In the best case, when all the loops are fully unrolled, the dataflow graph is acyclic and the clock frequency of the design is the data rate. In this paper, we develop a domain-specific compiler for programming FPGAs, called StReAm. StReAm is build on top of the module generation environment PAM-Blox
