Schematic diagram, at SRIO(serial RapidIO, Serial RapidIO) message format in, Ke Yitong
The packet crossing SRIO message carries QPI message, to transmit QPI affairs.
The present embodiment QPI message turns in the internet of RapidIO message and uses conversion equipment such as:
QPI interface conversion is RapidIO interface by Q2R equipment, utilizes RapidIO switching equipment flexible expansion
System equipment, it is possible to achieve substantial amounts of DDR, DIMM connect, it is achieved CPU and other processors exist
Isomery on framework.Owing to there is Q2R equipment, what processor node was seen remains Installed System Memory,
Can the Installed System Memory of greatly expansion service device；Change such as in CPU change or interface: at QPI
After upgrading to KTI (Intel's next generation's bussing technique), still can keep server system based on Q2R
System framework is constant, needs the simply Q2R equipment changed.
Fig. 3 is that the structure of the internet that the QPI message of another embodiment of the present invention turns RapidIO message is shown
It is intended to, as it is shown on figure 3, the CPU in main frame supports QPI agreement；Q2R equipment is conversion equipment, permissible
Transfer the bus QPI interface of CPU in main frame to RapidIO interface such as: SRIO interface, then pass through
RapidIO switching equipment (RapidIO SW) realize with memory system, association processing system, I/O system it
Between interconnection, it is achieved the QPI message of a kind of isomery interconnection turns the internet of RapidIO message.This feelings
Under condition, if cpu bus has change or is converted to other CPU, it is only necessary to upgrade interface conversion chip
(Q2R equipment).Backboard and other nodes can keep constant.In the present embodiment, first,
Q2R equipment can utilize the QPI affairs such as RapidIO message transmission QPI internal storage access, it is possible to achieve based on

QPI message point is make use of to turn the characteristic of internet of RapidIO message；Additionally, due at system upgrade
Or during agreement upgrading, it is not required to change whole system, it is only necessary to update the certain module in this system
, such as Q2R module, therefore, the design of the processor node of protocol conversion device is more modular,
Simplify, as long as export the RapidIO interface of RapidIO switching equipment, Ji Kelian through Q2R equipment
Receive in the internet that QPI message turns RapidIO message, it is achieved interconnection, association between processor process system
System and the connection of I/O device.
The present embodiment QPI message turns and uses Q2R equipment by QPI in the internet of RapidIO message
Interface conversion is RapidIO interface, utilizes RapidIO SW flexible expansion system equipment, it is possible to achieve
Substantial amounts of DDR, DIMM connect.Owing to there is Q2R equipment, what processor node was seen remains
Installed System Memory, can the Installed System Memory of greatly expansion service device；Change or interface change at CPU
Such as: after QPI upgrades to KTI, server system architecture based on Q2R can still be kept not
Become, need the simply Q2R equipment changed.
Fig. 4 is the structure that the QPI message of further embodiment of this invention turns the internet of RapidIO message
Schematic diagram, as shown in Figure 4, the Q2R equipment in main frame can utilize RapidIO message to transmit QPI
The QPI affairs such as internal storage access, between processor based on RapidIO switching equipment (RapidIO SW) mutually
Even, CC-NUMA(Cache-Coherent Non-Uniform Memory can therefore be realized
Architecture, cache coherent non-uniform storage accesses) framework.In order to realize CC-NUMA
Framework, can add cache coherence (Cache Coherence) submodule in Q2R equipment,
Thus realize framework based on memory expansion or the internal memory share framework of CC-NUMA.Cache one
Cause temper module mainly to realize maintenance and be distributed in each processor cache (Cache) the one of data
Cause property function.Restriction due to processor extended capability, it is impossible to safeguarded multiprocessor (more than 8)
Cache consistency function, therefore along with the increasing of processor number in interconnection architecture, need processing
Device intra-node increases the agency of cache coherence function.Cache coherence submodule generally has
Two kinds of implementations, one is based on bus monitoring agreement (Bus-Snooping Protocol), Yi Zhongshi
Based on directory protocol (Directory-based Protocol).QPI message turns the interconnection of RapidIO message
In network, have the Q2R equipment of cache coherence function can support 16 CPU, 32
