1.1 i.mx8MP Features
The i.MX 8M Plus is a powerful quad Arm® Cortex ®-A53 processor, with speed up to 1.8 GHz for C-Temp and 1.6 GHz for I-Temp, integrated with a Neural Processing Unit (NPU) of 2.25 TOPS that greatly accelerate machine learning inference. The vision engine is composed of two camera inputs and a HDR-capable Image Signal Processor (ISP) capable of 350 MPixels/s.The advanced multimedia capabilities include 1080p60video encode and decode H.265 and H.264. A 3D and 2D graphic acceleration supporting 1 GPixel/s, OpenVG 1.1, Open GL ES3.1, Vulkan, and Open CL 1.2 FP. Multiple audio and microphone interfaces for Immersive Audio and Voice systems. For industrial applications, real time control is enabled by an integrated 800 MHz Arm® Cortex®-M7. Robust control networks are possible via CAN-FD interfaces. And a dual Gb Ethernet, one supporting Time Sensitive Networking (TSN), drive gateway applications with low latency. High industrial system reliability for safety is leveraged by DRAM Inline ECC as well as ECC support on internal software-accessible SRAMs.
