Salient Features

SALIENT FEATURES

The engineering attributes in every bit-accurate VINJEY codec, and what they mean when you carry them from PC reference build to production silicon.

  • Bit-accurate decoders & encoders — output verified bit-for-bit against ISO/IEC (11172-4, 14496-26) and Bluetooth SIG golden reference bitstreams
  • Sample-accurate fast seek for instantaneous resume from any position in the stream
  • Hand-tuned DSP assembly inner loops — up to 35% CPU savings on Cortex-M and DSP cores
  • Deterministic static memory allocation — zero runtime malloc, fixed SRAM envelopes, no fragmentation
  • Fully reentrant, multi-instance safe architecture for multi-core systems and pre-emptive RTOS
  • Fixed-point 32-bit math — runs on DSPs and MCUs without a hardware FPU
  • Mask-ROM worthy — burned into production devices across tens of millions of units
Third-Party Dependencies
  • FMP3E (MP3 Encoder) implementation is based on Fraunhofer Technology (LSI Template Source Code)
  • HEAACv2 decoder is based on MPEG-4 HEAAC audio technology licensed by Fraunhofer IIS
  • WMA Standard and Lossless decoder implementation is based on Windows Media Porting Kit provided by Microsoft. We are an interim product licensee of the technology.
