i.MX8M CPU
iW-RainboW-G33M SMARC SOM can support i.MX8M CPUs from NXP. The i.MX8MFamily consists of three processors:
i.MX8M Quad Core, i.MX8M QuadLite & i.MX8M Dual Core. The Major Difference between i.MX8M CPUs are:
•
i.MX8M Quad Core
: 4 x Cortex-A53 & 1 x Cortex-M4F
•
i.MX8M QuadLite
: 4 x Cortex-A53 & 1 x Cortex-M4F (Hardware Acceleration not supported)
•
i.MX8M Dual Core
: 2 x Cortex-A53 & 1 x Cortex-M4F
The i.MX 8M Dual / 8M QuadLite / 8M Quad processors feature advanced implementation of a quad Arm® Cortex®-
A53 core, which operates at speeds of up to 1.5 GHz. A general-purpose Cortex®-M4 core processor is for low-power
processing. The DRAM controller supports 32-bit/16-bit LPDDR4, DDR4, and DDR3L memory. There are a number of
other interfaces for connecting peripherals, such as WLAN, Bluetooth, GPS, displays, and camera sensors. The i.MX
8M Quad and i.MX 8M Dual processors have hardware acceleration for video playback up to 4K, and can drive the
video outputs up to 60 fps. Although the i.MX 8M QuadLite processor does not have hardware acceleration for video
decode, it allows for video playback with software decoders if needed.
