Typhoon-Edge Power Estimator for Jetson AGX Orin Industrial + PolarFire SoC Systems

Typhoon-Edge power model

This estimator calculates an engineering power budget from the selected operating states. It is a planning estimate, not a qualification or certification result.

Released system scope

• Jetson AGX Orin Industrial: 248 TOPS, 12-core Arm CPU, 2048-core Ampere GPU, 64 GB ECC LPDDR5 and a 15-75 W module envelope.
• PolarFire SoC trusted control plane with DDR4, LPDDR4, redundant storage, dual 1Gb Ethernet, serial I/O, one SpaceWire link and camera acquisition interfaces.
• Typhoon-Edge input: nominal 12 V DC, continuous 12-36 V DC range and 150 W maximum equipment input.
• Storage and connectivity: 1 TB system NVMe, 1.92 TB mission NVMe, C7 PCIe switching, two PCIe x4 camera paths and two Jetson CSI-2 paths.

Power and efficiency

• Total Input Power is board load plus conversion losses at the selected input voltage.
• DC-DC Efficiency is calculated from actual modeled output load and VIN. It includes the input-to-5 V stage, low-voltage conversion, and the small LDO loss.
• Active Compute Core Utilization scales the Jetson CPU/GPU core domain from idle toward 12 CPU cores and 2048 GPU cores. It does not control the fabric.
• Fabric Utilisation independently scales Jetson GPU fabric power.

Thermal values

• Jetson Junction Temp Est. is an estimated Jetson module die junction temperature based on Jetson load, ambient temperature, and the calibrated load-soak curve.
• PolarFire Junction Temp Est. is a separate preliminary estimate based on PolarFire power and ambient temperature. It is not the Jetson temperature.
• Housing Temp Est. estimates the conduction-cooled enclosure temperature from ambient temperature plus total dissipated input power using a provisional 0.12 °C/W thermal rise. Replace this factor with measured cold-plate data for final design.

Peripheral sections

• Memory contains AGX LPDDR5 and PF DDR4/LPDDR4, each with Idle, Active, and Write states where applicable.
• Storage contains AGX system and mission NVMe plus PF eMMC and QSPI storage.
• Networking contains AGX 1GbE/10GbE and PF dual 1GbE plus 10GbE physical interface loads.
• PCIe x4 Cameras models only the Jetson-side PCIe interface electronics. Camera power is external and excluded.
• CSI-2 models the two Jetson camera inputs. Camera Link models PF Base, Medium, and Full activity.
• Serial I/O provides four RS-422, RS-232, CAN, and RS-485 channel groups. The design currently includes one SpaceWire link.

C7 PCIe topology

The switch uses one x8 upstream link when a switched endpoint is active. The NIC, mission NVMe, and PolarFire endpoint each add an x4 downstream branch. The displayed switch power changes with those endpoint states.

Rail budget

The rail view separates Jetson module 12 V, Jetson USB VBUS 5 V, Jetson PCIe/CSI 3.3 V, the system converter bus, and the broader system rail allocations. A zero Jetson 5 V value means both USB VBUS loads are off; CSI-2 is not a 5 V load.

Reference basis

Hardware scope is based on the released Typhoon Edge JAE Datasheet and User Manual/ICD revision 3.3, with Jetson AGX Orin Industrial compute specifications cross-checked against NVIDIA Jetson Orin product documentation. Component values remain engineering estimates until vendor measurements or board-level test data are available.
