The recommended power-up sequence is to apply power to the core voltage (VDD) first, followed by the input/output voltage (VDDIO), and then the clock signal. This ensures proper device operation and prevents latch-up or damage.
To optimize power consumption, use the device's power management features, such as dynamic voltage and frequency scaling, clock gating, and power-down modes. Additionally, optimize your software to minimize CPU usage and use low-power peripherals when possible.
The DM355 has an operating temperature range of -40°C to 85°C. However, it's recommended to operate the device within a temperature range of 0°C to 70°C for optimal performance and reliability.
To ensure reliable boot-up and operation, use a robust power supply, ensure proper decoupling and filtering of power rails, and implement a reliable boot loader and operating system. Additionally, use the device's built-in error detection and correction mechanisms, such as ECC and parity checking.
The DM355's video processing capabilities are limited by its clock speed, memory bandwidth, and available processing resources. It's recommended to carefully evaluate the device's performance and capabilities before designing a video processing system. Additionally, consider using external video processing accelerators or co-processors to offload computationally intensive tasks.
