NXP i.MX 8M processor series targets IoT audio, voice, video

January 05, 2017 //By Graham Prophet
NXP has configured the ARM-based i.MX 8M family of applications processors for audio and video system requirements in smart home and smart mobility applications. Their capabilities support full 4K UltraHD resolution, High Dynamic Range and advanced HMI for streaming media applications.

The i.MX 8M family has been designed to meet the needs of applications such as over-the-top (OTT) set-top boxes, digital media adapters, surround sound, sound bars, A/V receivers, voice control, voice assistance, digital signage and general purpose human machine interface (HMI) systems. The processors, NXP says, address the ‘major inflection points’ currently underway in streaming media: voice recognition and networked speakers in audio, and the move to 4K High Dynamic Range (HDR) and the growth of smaller, more compact form factors in video.

NXP’s i.MX 8M family of processors has up to four 1.5 GHz ARM Cortex-A53 and Cortex-M4 cores, flexible memory options and high-speed connectivity interfaces. The processors also feature full 4K UltraHD resolution and HDR (Dolby Vision, HDR10 and HLG) video quality, the highest levels of pro audio fidelity, up to 20 audio channels and DSD512 audio. The i.MX 8M family is tailored to streaming video devices, streaming audio devices and voice control applications. Capable of driving dual displays, the new devices include:

  • The i.MX 8M Dual/i.MX 8M Quad, which integrates two or four ARM Cortex-A53 cores, one Cortex- M4F core, a GC7000Lite GPU and 4kp60, h.265 and VP9 video capability;
  • The i.MX 8M QuadLite, which integrates four ARM Cortex-A53 cores, one Cortex- M4F core and a GC7000Lite GPU;
  • The i.MX 8M Solo, which integrates one ARM Cortex-A53 core, one Cortex-M4F core and a GC7000nanoULTRA GPU.
