Abstract FPGAs can potentially deliver tremendous acceleration in high-performance server and em- bedded computing applications. Whether used to augment a processor or as a stand-alone device, these reconfigurable architectures are being deployed in a large number of implemen- tations owing to the massive amounts of parallelism offered. At the same time, a significant challenge encountered in their wide-spread acceptance is the laborious efforts required in programming these devices. The increased development time, level of experience needed by the developers, lower turns per day and difficulty involved in faster iterations over designs affect the time-to-market for many solutions. High-level synthesis aims towards increasing the productivity of FPGAs and bringing them within the reach software developers and domain experts. OpenCL is a specification introduced for parallel programming purposes across platforms. Applications written in OpenCL consist of two parts - a host program for initialization and management, and kernels that define the compute intensive tasks. In this thesis, a compilation flow to generate customized application-specific hardware descrip- tions from OpenCL computation kernels is presented. The flow uses Xilinx AutoESL tool to obtain the design specification for compute cores. An architecture provided integrates the cores with memory and host interfaces. The host program in the application is compiled and executed to demonstrate a proof-of-concept implementation towards achieving an end-to-end flow that provides abstraction of hardware at the front-end.
