Product Details
GIF is a common file format used in Windows for handling graphics files. It uses LZW compression format. 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. 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.
- 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
