PCoIP Technology: A New Beginning for the Personal Computer

To create a PCoIP system, Teradici provides a two-chip solution that delivers the user's desktop over a

standard IP network. The PCoIP Host Processor is used in the centralized host PC or workstation, while the

PCoIP Portal Processor is used in a small, stateless desktop "portal" appliance. Figure 1 shows datacenter

equipment integration options for the PCoIP Host Processor including PC blades, workstation blades, server

blades, rackmount workstations, or tower PCs. The PCoIP Host Processor is tasked with encoding the complete

desktop environment. The encoded desktop is then communicated in real time over an IP network such as an

enterprise network to a PCoIP Portal Processor-enabled desktop. Now any PCoIP system user can enjoy the

true PC user experience they are accustomed to with the security, reliability and efficiency of fully centralized

computing.

Data Center

The PCoIP Host Processor, as shown in Figure 2 receives standard Digital Visual Interface (DVI) display data

from the PCs graphics processor. The PCoIP Host Processor also uses a PCIe link for transparent bridging of

HD audio devices and USB peripherals. Prior to network transmission, the PCoIP Host Processor compresses

the video stream in real-time, optionally compresses the audio and combines the bridged USB traffic. The

combined data is AES encrypted at wire-speed and sent to the network using the on-chip integrated

10/100/1000 Ethernet MAC.

The PCoIP Host Processor employs sophisticated image compression techniques to minimize desktop encoding

system latency and reduce peak network bandwidth. Compared to competing technologies, the PCoIP image

compression and transport algorithm is designed to provide the best user experience at any available network

bandwidth. The PCoIP Host Processor continuously monitors and adjusts the image compression rate to ensure

the optimal user experience for the available bandwidth. In all cases, static regions of the display image will be

refined to be an exact replica of the image rendered on the host PC. This is a key requirement for visualization

applications such as CAD or medical diagnostics.
