Implementing computations in hardware can offer better performance and power consumption than a software implementation, typically at a higher development cost. Current hardware/software co-design methodologies usually start from a pure software model that is incrementally transformed into hardware until the required performance is achieved. This is often a… (More)
— John von Neumann proposed his famous architecture in a context where hardware was very expensive and bulky. His goal was to maximize functionality with minimal hardware. Presently, logical gates are nearly free and single chips will soon contain billions of gates. However, most current designs are still based on Von Neumann's architecture because… (More)
We compare the recently proposed Discriminative Restricted Boltzmann Machine to the classical Support Vector Machine on a challenging classification task consisting in identifying weapon classes from audio signals. The three weapon classes considered in this work (mortar, rocket and rocket-propelled grenade), are difficult to reliably classify with standard… (More)
We describe a prototype compiler that compiles general functional programs into dataflow parallel hardware. The compiler supports non-tail function calls and higher-order functions. Our approach makes it possible for software developers to design hardware embedded systems with little prior knowledge of electronic circuits.
