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).
