The SSD201 is a highly integrated SOC. Based on ARM Cortex-A7 dual-core, it integrates H.264/H.265 video decoder, 2D graphics engine, TTL/MIPI display with adjustable picture quality engine and other useful peripherals for smart display applications.
A typical utilization of the SSD201 application processor is demonstrated in the block diagram. The completed system includes a connectivity module (Wi-Fi or Ethernet), and a non-volatile storage (NOR flash, NAND flash or SD card). External crystal of 32KHz frequency is used to drive the Real Time Clock (RTC), which can keep time scale when the main system clock is off. The H.264/H.265 engine decodes video streams from network and sends them to the display sub-system.
Before outputting to TTL or MIPI TX panel, the images can be enhanced with respect to brightness/contrast/saturation/sharpness to give the best picture quality. The NOR or NAND flash is usually reserved for operating system and application software. Moreover, other peripherals like SAR ADC, Audio ADC/DAC, UARTs, PWMs, GPIOs and SPI are supported to realize applications with maximal flexibility.
Besides, the SSD201 supports secure booting and personalization authentication mechanism for securing system. The AES/DES/3DES cipher engines could also help encrypt the compressed video/audio streams to protect privacy.
