製品概要BMP is a common file format used in Windows for handling graphics files. It can either use an uncompressed data format or an RLE encoder data. This implementation is highly optimized for Analog Devices ADSP-BF5xx Blackfin processors. The data movement for the module can be configured for either cache mode or through MDMA. It is a self-contained software component that has been rigorously tested.
Each module supports the Analog Devices, Inc. (ADI) Blackfin or SHARC Processor family and is a licensed product that is available in object code format. Recipients must sign or accept a license agreement with ADI prior to being shipped or downloading the modules identified in the license agreement.

- Performance (average cycles per pel) measured on ADSP-BF533.
- MIPS is measured as ((cycles/pel) * (image width) * (image height) * (frames/second) / 10^6). (It is assumed that frames/second = 15 for calculation)
- Code compatible across all ADSP-BF5xx processors, with silicon anomaly workarounds implemented for ADSP-BF527(0.2), ADSP-BF533(0.5), ADSP-BF548(0.2) and ADSP-BF561(0.5)
