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
