The STV0991 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.


Video analytics accelerators unload the central CPU from intensive repetitive tasks. A graphics renderer unit compensates for perceptual distortion produced by wide-angle lenses (such as fish-eye) and inserts graphical and/or textual information over the video. 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 development process. The application diagram suggests some of the applications possible through combining optional elements as required.
