CMS firmware polls for sensor information from the satellite controller approximately every 120 ms, communicating via a UART interface and GPIO handshake lines. CMS firmware processes sensor information and writes instantaneous, maximum, and average values to a shared memory (memory mapped) for collection by the host software. The host software must poll the shared memory (REG_MAP) for updated sensor information.

Sensor information is gathered and monitored for:

  • Voltage
  • Current
  • Temperature
  • Power
  • Fan Speed
Note: Fan speed is reported only for active cards with local fans. Passive cards do not contain fans.
Note: HBM Temperature reporting must be enabled on compatible Alveo cards via the REG_MAP control register (CONTROL_REG).
