Mainstream processor chips, both in high performance and low power segments, are increasingly integrating additional functionality such as graphics, display engines, security engines, PCIe™ ports (i.e., ports in accordance with the Peripheral Component Interconnect Express (PCI Express™ (PCIe™)) Specification Base Specification version 2.0 (published Jan. 17, 2007) (hereafter the PCIe™ specification) and other PCI-e™ based peripheral devices.
Traditional peripheral hub product designs are highly segmented due to varying requirements from the server, desktop, mobile, embedded, ultra-mobile and mobile Internet device segments. Different markets seek to use single chip system-on-chip (SoC) solutions that combine at least some of processor cores, memory controller hub (MCH), input/output controller (ICH) and other segment specific acceleration elements onto a single chip. However, designs that accumulate these features are slow to emerge due to the difficulty of integrating different intellectual property (IP) blocks on a single die to standard internal interconnects.
