Product Details
TIFF is a lossless decoder which can be used as a contained for archiving. The implementation is highly optimized for Analog Devices ADSP-BF5xx Blackfin processors. This release will work on image cached from L3 memory. It is a self-contained software component that has been rigorously tested. It contains an intuitive C-callable API that is interruptible, maintains flexibility and provides seamless system integration.
Licensing
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. The code and data are cached from L3 memory
- 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 based on the following boards.
- "Data RAM" for one instance, includes Scratch and Instance/State. Input buffer size is 2 KiB and output buffer size is 1 KiB
