abstract.

Two key components in configurable system-on-chip(CSoC) devices are
instruction processors and field-programmable logic. This paper 
describes a framework, based on the Pebble language, that can be 
used to produce parameterized hardware libraries. Such libraries 
facilitate the development of user-defined hardware on the field-
programmable logic to enhance the capability of the instruction 
processors in CSoC designs. Libraries are presented that support 
parameterization of the amount of pipelining and serialization to
provide implementations with different trade-offs in resource usage 
and performance. These libraries have been developed to meet the 
requirements in terms of efficiency, validability and ease of use.
A case study involving DES encryption for Triscend E5 devices is 
presented.
