Pebble: A Language for Parametrised and Reconfigurable Hardware Design

Abstract. Pebble is a simple language designed to improve the productivity and effectiveness of hardware design. It improves productivity by adopting reusable word-level and bit-level descriptions which can be customised by different parameter values, such as design size and the number of pipeline stages. Such descriptions can be compiled without flattening into various VHDL dialects. Pebble improves design effectiveness by supporting optional constraint descriptions, such as placement attributes, at various levels of abstraction; it also supports run-time reconfigurable design. We introduce Pebble and the associated tools, and illustrate their application to VHDL library development and reconfigurable designs for Field Programmable Gate Arrays (FPGAs).
