color space components are stored at non-unit

strides and, second, intermediate results can be larger than

8 bits. In this paper we show that extended subwords and

the Matrix Register File (MRF) can be employed to mitigate

these limitations.

significantly by accelerating color space conversion.

Since color space conversions exhibit significant

amounts of data-level parallelism, they could be implemented

using Single-Instruction Multiple-Data (SIMD) instructions.
