Bitmap Image File (BMP) Decoder
The Bitmap Image File (BMP) Decoder library for the Blackfin processor implements data handling for BMP data as uncompressed data format or an RLE encoder data.
- Conformant to Microsoft Version 3
- Cache: Both Instruction and Data Cache enabled
- MDMA: One channel Memory DMA is used
- Code compatible across the Blackfin Processor Family ADSP-BF5xx
- MISRA-C compliant
- Target Processors: ADSP-BF561, ADSP-BF533, ADSP-BF527, ADSP-BF548
- Release format : Object Code with source code wrapper
- Input format: BMP data stored in 24bpp color, BMP data stored in 16bpp color, BMP data stored with a palette and in 8bpp color or less and BMP data stored encoded in either RLE4 or RLE8
- Output format: RGBA
- Image size: User configurable
- Multi instancing: Fully re-entrant and multi-instance capable

- 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)
- "Data RAM" for one instance, includes Scratch and Instance/State
