text: Intel recently introduced the Heterogeneous Architecture Research
Platform, HARP. In this platform, the Central Processing Unit and a Field-Programmable
Gate Array are connected through a high-bandwidth, low-latency interconnect and
both share DRAM memory. For this platform, Open Computing Language (OpenCL), a
High-Level Synthesis (HLS) language, is made available. By making use of HLS,
a faster design cycle can be achieved compared to programming in a traditional
hardware description language. This, however, comes at the cost of having less
control over the hardware implementation. We will investigate how OpenCL can be
applied to implement a real-time guided image filter on the HARP platform. In
the first phase, the performance-critical parameters of the OpenCL programming
model are defined using several specialized benchmarks. In a second phase, the
guided image filter algorithm is implemented using the insights gained in the
first phase. Both a floating-point and a fixed-point implementation were developed
for this algorithm, based on a sliding window implementation. This resulted in
a maximum floating-point performance of 135 GFLOPS, a maximum fixed-point performance
of 430 GOPS and a throughput of HD color images at 74 frames per second.
