About the EEMBC OABench™ Performance Benchmark Suite

NEW! OABench is now available on our GitHub page.

OABench 2.0 is a second-generation suite of benchmarks that allows the user to approximate the performance of processors in printers, plotters, and other office automation systems that handle text and image processing tasks. Compared to OABench 1.1, it includes new Ghostscript and Bezier benchmarks as well as new datasets and self-checking features. Even if you’re not working on a printer or image processing application, the demanding workload provided by OABench 2.0 will stress processors at all levels.

Its five benchmark kernels include the following:

Bezier

Benchmarks the classic Bezier curve algorithm by interpolating a set of points defined by the four points of a Bezier curve.

Dithering

The benchmark uses the Floyd-Steinberg error diffusion dithering algorithm.

Ghostscript

Provides an indication of the potential performance of an embedded processor running a PostScript printer engine. OABench 2.0 can be run with or without this benchmark.

Image Rotation

The benchmark uses a bitmap rotation algorithm to perform a clockwise 90° rotation on a binary image.

Text Parsing

The benchmark parses Boolean expressions made up of text strings and tests bit manipulation, comparison, and indirect reference capabilities to test the potential performance of a printer interpretive control language.

OABench Benchmark Scores

You can view historical scores for OABench.

EEMBC benchmark characterization data allows designers to better understand how to interpret EEMBC benchmark scores relative to certain processor characteristics. The Kiviat graph above, which visualizes multivariable data in a way that easily reveals program behavior, shows workload characteristics for the Image Rotation benchmark within OABench. This data was taken from a characterization done by North Carlonia State University.
