an FPGA-based system controller, called “Qixis”, which manages several critical system features, including: • Reset sequencing • Power supply configuration • Board configuration • hardware configuration
The qixis registers are accessible over one or more system-specific interfaces, typically I2C, JTAG or an embedded processor.
