Description
Technical field
The present invention relates to a kind of computer system, and particularly relate to a kind of computer system with processor expanding apparatus.
Background technology
Along with the processing requirements to computer system is more and more higher, computer system except uniprocessor, promptly having single central processing unit in computer system carries out outside all computing work, developed at present the computer system that to have multiprocessor, surpass more than one central processing unit by in computer system, being provided with, in the mode of time-division processing or parallel processing, handle a large amount of computings to promote the usefulness of computer system.
The Hyper of ultra micro (AMD) Opteron server utilization at present Transport technology, processor to processor and processor in the application of I/O, mode with parallel or serial bus provides quite low delay, and the point-to-point transmission scheme of frequency range performance greatly.On the other hand, for the multicomputer system of using the HyperTransport technology, in order to obtain the processor efficiency optimization, the number that is disposed at the processor on the motherboard in the system is generally 2 or 4 processors.In addition, existingly on the market operate in mode, break the physics inertia of general processor number at 3 processors of motherboard deploy as IBM System x3755 server, and the successful more flexible multiprocessor computer system deployment scheme of acquisition.
Though yet computer system can be in providing high frequency range, the low transmission channel that postpones by Hyper Transport technology between processor, System on Chip/SoC and each perimeter component on the motherboard, for HTX (the Hyper Transport eXtension) expansion slot of supporting HyperTransport, the function how its open-ended HTX adapter only provides I/O to expand.Even can dispose the server of 2-4 processor as described above, processor still is deployed on the motherboard in advance, and its configurable number is a fixed number, can't dynamically expand.
In addition, the mode of past processor access storer all is by the data in the ability of the north bridge chips in the system chipset access memory, that is to say that Memory Controller (memory controller) is integrated in the north bridge chips.And in order to alleviate the burden of north bridge chips, aforementioned 0pteron processor directly will be built in the Memory Controller in the processor chips, also further reduces the situation of signal delay between processor and storer simultaneously.Under such situation, each processor all has independently memory resource on the motherboard, also can share the memory resource of other processor control.For the computer system of a multiprocessor, more therefore the number of processor is subject to the area (area of the storer that need configuration processor and each processor are independently controlled) of motherboard and can't be expanded, so that known multiprocessor computer system possesses 2-4 processor more, if need further to increase the processor number to promote the treatment efficiency of computer system, then be difficult to realize.
Summary of the invention
The present invention provides a kind of computer system with processor expanding apparatus, and it includes a motherboard, has an expansion slot; One first processor is installed on this motherboard; And a processor expanding apparatus, including one second processor, this processor expanding apparatus is electrically connected on this expansion slot in the mode of plug.Wherein when this processor expanding apparatus was electrically connected on this expansion slot, this first processor was to be connected with this second processor by a bus interface.
The present invention also provides a kind of processor expanding apparatus, is used for being electrically connected on the expansion slot of a motherboard in the mode of plug, and this processor expanding apparatus includes a processor and a power module.This power module is to be used to provide power supply to give this processor.Wherein when this processor expanding apparatus is electrically connected on this expansion slot, this processor is to be connected with processor on the motherboard by a bus interface.
The present invention utilizes on the expansion slot of supporting to meet this bus protocol and a processor expanding apparatus is installed to reach the purpose that expands processor in computer system in having the computer system that meets a unified bus protocol.Have one or more than one processor and corresponding storer on the processor expanding apparatus, when processor expanding apparatus is installed on computer system, ROM-BIOS in the computer system is transplanted (porting) operation to the bus route (bus routing) of processor on the processor expanding apparatus, and the storer on it carried out addressing, make computer system when processor expanding apparatus is installed, expand the number of processor and storer.
