Overview
This is a versatile system-on-chip device designed for automotive, security and a multitude of other camera applications. From video and audio input through HDR image signal processing, lens distortion correction, graphics overlay, video compression, video analytics acceleration, CPU, operating and non-volatile memory, media access controller, to video and audio outputs and communication interfaces, it comprises all elements to support compact, low bill-of-material and low energy-consumption camera applications. No external memory chips such as DRAM or Flash are required for its operation, predictive H.264 video encoding inclusive. Resulting ready-for-display video can be output as-is over the parallel or serial video output port, or real-time compressed for streaming out through one of: RGMII/GMII, SDIO or SPI interfaces. An audio signal can be input through either an I2S or a PDM input, processed by the CPU and inserted into the output data stream. A return audio channel is also supported, outputting the audio on an I2S output. Precise Time Protocol (PTP) support and other provisions on the die allow precise instant-of-exposure synchronization of cameras in a multi-camera system, independent of cable lengths. A cryptographic and hash unit permits protection of customer intellectual property embedded in their software. Flash content can be updated via communication interfaces, thus allowing non-intrusive customer firmware updates. A debug access port (DAP) helps users in their software

It is very important that the design aspects of the NB-IoT device protocol stack ensure low module cost and low energy consumption. This is required to match the industry expected module costs. This paper outlines some of the NB-IoT Protocol stack specification flexibilities and generic design aspects that are to be considered to meet the above requirements, especially with reference to LTE.
