The VITA 46 11 2022 software IP core implements all requirements defined for a Tier 3 IPMC Typical target platforms of this software core are OpenVPX and SOSA aligned payload modules which interface to a Chassis Manager through the IPMB interfaces on the backplane.

The bare metal C implementation is lightweight and supports various microcontroller architectures such as ARM and RISC V Functions that make use of dedicated microcontroller peripherals are provided as part of reference designs, for example the I 2 C controller of the Microchip SAMV 71 or the PolarFire ® RISC V SoC Other microcontroller designs can be made available on request.

The IP core is delivered with an FRU and an SDR compiler utility The SDR compiler takes sensor values and thresholds provided by the customer using the delivered SDR excel template It generates required SDR data to be uploaded to the flash of the IPMC Different output formats are available supporting standard file formats such as hex and bin, suitable for automated programming during board production.

Hybrid DSP provides support with integration or can fully implement customers board management and IPMC functionality.
