Modern SoC / NoC chips often provide GeneralPurpose I/O (GPIO) pins for connecting devices that are not directly integrated within the chip. Timing accurate control of devices connected to GPIO is often required within embedded real-time systems — ie. I/O operations should occur at exact times, with minimal error, neither being significantly early or late… CONTINUE READING
