  • 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
