Recursive variable expansion: A transformation for reconfigurable computing

Reconfigurable computing, in which general purpose processor (GPP) is augmented with one or more FPGAs, is increasingly used for high-performance computing where massive fine-grain parallelism and pipelining can be exploited. A challenge is to exploit such massive parallelism on FPGAs and more specifically how to map an application on the...

Arithmetic soft-core accelerators

In this dissertation, we address the design of multi-functional arithmetic units working with the most common fixed-point number representations, namely: unsigned, sign-magnitude, fractional, ten's and two's complement notations. The main design goal is to collapse multiple complex arithmetic operations into a single, universal arithmetic unit,...

The Molen Polymorphic Media Processor

In this dissertation, we address high performance media processing based on a tightly coupled co-processor architectural paradigm. More specifically, we introduce a reconfigurable media augmentation of a general purpose processor and implement it into a fully operational processor prototype. The proposed media Molen prototype is implemented on...
