Abstract

A modular computer system (20) including a universal connectivity station (UCS) (22) interconnected to a plurality of remote modules (30, 32, 34, 36, 38, 42) via a plurality of respective high speed serial links (26, 40) such as based on proprietary Split-BridgeTM technology. The plurality modules, including a processor module (42) which may include core parts including a CPU, memory, AGP Graphics, and system bus interface may be remotely located from each of the other modules, including the UCS (22). The present invention achieves technical advantages wherein each module of the modular computer system (20) appear to each device to be interconnected to the other on a parallel bus since the high speed serial links appear transparent. Preferably, although not necessary, each of the modules including the UCS (22) are based on the PCI bus architecture, or the PCMCIA bus architecture, although other bus architectures are well suited to be incorporated using the present invention. The processor module can be upgraded to change or improve the performance of the modular computer system (20) without requiring any changes to the remaining system, thus drastically improving the price to performance trade-offs of the system. Moreover, the operating system (OS) of each module, including both the software and harware, do not need to be changed as the entire modular system (20) is based on a common architecture, such as the PCI
or Cardbus bus architecture.

Claims (20)
