NXP公司的i.MX 8M Dual／8M QuadLite／8M Quad应用处理器是基于四核Arm®Cortex®-A53,工作速率高达1.3GHz,可连接音频／视频设备,扫描／图像设备,以及需要高性能低功耗处理器的各种设备.其DRAM控制器支持32位／16位LPDDR4,DDR4和DDR3L存储器,以及连接外设如WLAN,蓝牙,GPS,显示和照相机传感器.应用处理器的硬件加速可使视频播放高达4K,驱动视频输出高达60fps,主要可用在汽车电子和工业控制.本文介绍了i.MX 8M处理器主要特性,应用处理器框图以及i.MX 8X多传感器实现板(MEK)主要特性和电路图.

The i.MX 8M Dual／8M QuadLite／8M Quad processorsrepresent NXP’s latest market of connected streamingaudio／video devices, scanning／imaging devices, andvarious devices requiring high-performance, low-powerprocessors.

The i.MX 8M Dual／8M QuadLite／8M Quad processorsfeature advanced implementation of a quad Arm®Cortex®-A53 core, which operates at speeds of up to1.3 GHz. A general purpose Cortex®-M4 core processoris for low-power processing. The DRAM controller supports 32-bit／16-bit LPDDR4, DDR4, and DDR3Lmemory. There are a number of other interfaces forconnecTIng peripherals, such as WLAN, Bluetooth, GPS,displays, and camera sensors. The i.MX 8M Quad andi.MX 8M Dual processors have hardware acceleraTIonfor video playback up to 4K, and can drive the videooutputs up to 60 fps. Although the i.MX 8M QuadLiteprocessor does not have hardware acceleraTIon for video decode, it allows for video playback with softwaredecoders if needed.
