Abstract

In this work, we explore a new family of coarse grain reconfigurable architecture called BRICK, which is capable of mapping complete expressions and pipelines into one processing element with Multiple-Input, Multiple-Output characteristics while provided with a centralized control unit to synchronize the operation of each Processing Element (PE). Each PE has heterogeneous ALUs specialized in a particular type of operation. These ALUs can be interconnected to implement complex expressions, either sequential or combinational, increasing computational density and utilization rate of the reconfigurable Array. Preliminary synthesis results and application examples show that efficient mappings can be achieved with BRICK.
