Actel teamed with Pigeon Point Systems to develop IP core enhancements for hardware platform management applications. The DirectCore enhancements strengthen the suitability of Actel Fusion mixed-signal FPGAs for local xTCA management controllers, and especially xTCA applications, for which Pigeon Point offers the Board Management Reference (BMR) series.
New and Improved DirectCore Building Blocks
CoreLPC v2.0 is a new core that provides an APB3-compliant interface to the Low Pin Count (LPC) pin-reduced subset of the Peripheral Component Interconnect (PCI) bus. It also provides an LPC-based implementation of the Keyboard Controller Style (KCS) interface registers that are defined in the Intelligent Platform Management Interface (IPMI) specification. Fusion-based xTCA management controllers that incorporate CoreLPC can communicate with unmodified IPMI-compliant applications running on their corresponding payload processors.
CorePWM v4.0 adds the capability to measure the frequency of fan tachometer signals. When combined with the current pulse width modulated (PWM) output capabilities of this block, the tachometer input function enables closed loop fan management, and thus Fusion-based xTCA management controllers for fan trays.
CoreI2C v6.0 implements an interface to the I(2)C bus that includes key in-box management links based on the Intelligent Platform Management Bus (IPMB). The updated core adds support for a multi-channel configuration to reduce tile consumption in FPGA designs that require many I(2)C interfaces. Implementing separate I(2)C channels for each AdvancedMC slot in AdvancedTCA and MicroTCA carriers improves the robustness and performance of these critical in-box management links.
