Integrated Baseboard Management Controller (iBMC)

The WPCM450 is a combined Baseboard Management Controller (BMC), 2-D and VGA-compatible Graphics Core with PCI interface, Virtual Media and Keyboard, and a Video and Mouse Redirection (KVMR) module. It supports a variety of chipsets and integrates blade-oriented SuperI/O functionality sufficient for a legacy-reduced server.

The WPCM450 KVMR module (patent pending) compresses the video stream for transmission via LAN, and uses a USB node for Keyboard and Mouse redirection.

The WPCM450 is optimized for the Intelligent Platform Management Interface (IPMI) and the System Management Architecture for Server Hardware (SMASH) specifications. The WPCM450 controls board functions, handles LAN communications through the Reduced-pinout Media Independent Interfaces (RMII) and handles the KVMR module. The WPCM450 emulates Keyboard and Mouse redirection and Virtual Media (VM) via the USB.

The WPCM450 features an SPI interface with dual access from both the BMC and the host, usable for BMC firmware and host boot flash. It supports address map forcing to access two BIOS code and data sets (rolling BIOS) on this interface. The WPCM450 has a parallel 8-bit bus (X-Bus) for I/O expansion.
