H.264 Baseline Profile Encoder

Product Description

This implementation of the H.264 Baseline Profile Encoder has been highly optimized to run on the Analog Devices ADSP-BF5xx Blackfin processor. It is a self-contained software component that has been rigorously tested and validated with JM reference decoder and commercial decoders for the conformance with ITU-T H.264 standard. It contains an intuitive C-callable API that is interruptible, maintains flexibility and provides seamless system integration.

Performance Metrics

MIPS summary:

Code Memory (KB) Data RAM (KB) Fame Buffer (MB) Output Buffer (MB) Input Buffer (MB) Cycles/pel (MIPS)
Average Moving Average Peak
55.59 40.64 1.37 1.00 1.08 87 (902) 103 (1067)
  • Cycle Count measured using a bit rate of 1.0mbps, 25 fps, 720x576 (PAL D1) image size, ITU-R BT.656 input, PAL format, optimal memory layout, ADSP-BF561 rev 0.5 processor, ADI Defined Surveillance Profile using surveillance camera content.
  • Measuments done with CAS 1[1] =3 for SDRAM, CCLK 2[2] =600, SCLK 3[3] =120 for ADSP-BF561
  • Data cache and instruction cache are enabled. The cache is set in "write back" and "small cache" (DCBS=0) mode
  • Memory DMA is used with 32 bit DMA
  • "Data RAM" for one instance includes Stack, Scratch, Constant Data Tables, Encoder Instance Memory, Encoder Scratch Memory allocated by application for D1 PAL resolution
  • Frame Buffer for one instance of encoder and D1 PAL resolution
  • Minimum Input and Output Single Buffers, for ITU-R BT656 D1 PAL input
  • 1 MB = 1024 KB; 1 KB = 1024 Bytes
  • NOTE: In deriving the "Moving Avg Peak" value, an 8 consecutive frame sliding window was used. An average cycle count was measured for each window of frames, and the worst case average cycle from all the sliding window measurements was determined to be the "Moving Avg Peak" value
