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.

Performance Metrics

MIPS summary:

			Memory (Bytes)				Performance
Module	Image Width	Image Height	Code	Stack	Data RAM	Data ROM	Average Cycles / pel	MIPS
Decode GIF	225	65	6008	196	43744	--	171.51	37.62

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
