Description
Technical field
The present invention relates to field of computer, particularly accelerate Computer Processing speed technology, is a kind of virtual hardware accelerating method and system concretely.
Background technology
Along with social development of science and technology, computer processing speed is advanced by leaps and bounds, and the very huge need of work relevant hardware accelerator card of some data processing amounts of current computer realm assists central processing unit to carry out work.On the electronic market, run into some and be called PC hardware such as graphics acceleration card, sound blaster through regular meeting.These cards can be born most of video or audio decoder work, alleviate the work load of CPU.These decoding of hardware internal dedicated video or audio decoder chips are realized decoding on hardware-level, the speed of decoding and quality are all than using software decode to be greatly improved hardware-accelerated technology that Here it is.
Hyper-Threading belongs to the multithreading of Intel version.This technology can allow single CPU have the ability of handling multithreading, and physically only uses a processor.Hyper-Threading is provided with two inlet-AS (Architecture State, architecture states) interface for each concurrent physical processor, thereby makes softwares such as operating system that it is identified as two logic processors.As Chinese patent 98811883.1, multithread data processor has disclosed a kind of equipment of handling the DAB video data, how to call a plurality of processes with more reasonably collaborative work.Such multiline procedure processor is handled very big again help for the multi-process in the operating system, can finish a plurality of processes more fast.Though multithreading attains a yet higher goal computer processing speed, the breakthrough on computer hardware speed and to improve the processing speed of application program very difficult.
And can not be on computer motherboard for some are used the too many hardware accelerator card of unconfined grafting, this virtual hardware technology just occurred.
Often can use virtual units such as similar virtual drive and virtual floppy disk now.Virtual drive uses virtual equipment interface and certain hard drive space to realize; Virtual floppy disk uses memory headroom to realize.This technology has been improved the performance of equipment read-write interface and the performance of equipment itself, and read or write speed is greatly improved.As Chinese patent 00107490.3, ultra-large-capacity virtual optic disk file system building approach and system thereof have disclosed in this case and how to have managed the principle that re-constructs a reflection ultra-large-capacity virtual optical disc storage system by the routing table of original physical CD.
Because Windows allows to move simultaneously a plurality of tasks, when so a plurality of processes occurring and attempting to visit the situation of same physical equipment simultaneously, if a plurality of virtual machines (VM:Virtual Machine) attempt to visit same physical equipment, because the DOS application program can be manipulated hardware directly, so must carry out virtual to this equipment, the virtual device driver of a virtual equipment (VxD:Virtual Device Driver) is responsible for detecting the situation that a plurality of VM attempt to visit same equipment reliably, and the strategy of taking to arbitrate solves this conflict.
The work of VxD is to provide an environment with hardware interface to application code, for the state of each guest virtual machine management virtual device, arbitrates a plurality of application programs pellucidly, simultaneously bottom hardware is conducted interviews and managing hardware device.VxD is one and manages for example hardware device or 32 executable programs of system resource such as install software, makes several application programs can use these resources simultaneously.Windows allows to realize multitask based on the application program of Windows by using VxD.VxD with the handling interrupt in the work that is connected of Windows, and carry out the I/O operation, and do not influence the execution of other application programs for carrying out the I/O application program operating.The notion that Here it is so-called " virtual ".
VxD moves under the monitoring of virtual machine manager VMM (Virtual Machine Manager), and VMM is actually a special VxD.VMM carries out the work relevant with system resource, virtual machine environment (can produce, dispatch, unload virtual machine) is provided, responsiblely dispatches the multithreading work such as timeslice and managing virtual internal memory of taking the lead.VxD and VMM operate in outside other any virtual machines, and VxD in fact is exactly a part that realizes virtual machine technique.
VxD can load also dynamic load or unloading as required with VMM is static.Just because of the close cooperation between VxD and the VMM, just make VxD have the not available ability of application program, such as access hardware devices without restriction, arbitrarily check operating system data structure (as descriptor table, page table etc.), visit any region of memory, catch software interruption, catch I/O port operation and internal storage access etc., even can also intercept hardware interrupts.
The VxD technology is adopted in the realization of virtual drive.Principle is as follows:
In the time of VxD independent access physical equipment, allow a VM accesses virtual equipment, this is the most complicated virtual form.As VCD (Virtual Com Device), the VCD buffer zone receives serial data and interrupts passing to pellucidly a corresponding VM by mapping, VM reads the serial data register in the Interrupt Process process, the essence of these data is data that the VCD buffer zone has received.
The same with physical equipment, hardware interrupts many times also must be virtual, and this situation is more complicated.The interrupt map that virtual interruption produces hardware in fact exactly is to each VM that needs it (no matter whether this VM moves), and alternative VxD serves.
The control procedure of VxD must be able to be handled special message a: W32_DEVICEIOCONTROL.The application program that VMM replaces calling the DeviceIoControl function sends this message to VxD.Message parameter can be determined VxD message response function, inputoutput buffer pointer and buffer size, and is bundled in the DIOCPARAMETERS structure.By this interface, not only can read-write equipment, and can also between application program and VxD, pass pointer mutually, thus reach the purpose of special applications.
The processing procedure of virtual drive is as follows:
1, the dynamic or static virtual drive driver that loads
2, load the ISO file
3, open the ISO file system and read file header information
4, read file
5, unloading ISO file
Unloading virtual drive driver (the static loading of Windows do not need unloading).
Dynamic link library is a kind of technology commonly used in the prior art, in an application system, moving a plurality of processes simultaneously, program is at first hinted obliquely at the function of dynamic link libraries in the program process when calling dynamic link libraries, and application program is a function maintenance operation site environment.Because each consumer process all has the process space of oneself, even use dynamic link libraries, each process still oneself is safeguarded the running environment of oneself, can not shared data between each process.The shared object data have only each process to load respectively if desired.The method of operating of object is by each process independent loads and occupy, the data of object are relying on file system and operating system to guarantee consistance, maintaining file system and operating system consistance also have independently kernel process finish, and this all has very big loss for reliability and efficient.
Such as in mail filtering system, Chinese mail need carry out pre-service to Chinese.Chinese dictionary need be shared by all mail treatment processes as a public part.The method of communication has shared drive, Socket, semaphore etc. between the process traditionally, but common characteristic problem of these methods, a shared data, method of operating that can not shared data.Method of operating that can not shared data will cause each process that the complete dictionary of one cover and the handling function of dictionary must be arranged.Reach the data of both sharing dictionary, the method for operating of sharing dictionary must adopt a kind of new technological means again.
