Description
Technical field
The utility model relates to a kind of computer circuit board, relates in particular to a kind of based on microprocessor embedded computer circuit board.
Background technology
COM Express (TM) is the microprocessor calculator modules standard of a PICMG definition, and the interface of its definition is carried the common platform that original counter parallel interface is transformed into LVDS high speed serialization signal interface.COM Express (TM) has defined various electric signals and has arranged the demand that definition is used for following each different aspects.So-called " COM " is exactly Computer-On-Module, be about to a Highly Integrated CPU and minimum system thereof and make a Module, and this Module can be inserted on the Carrier Board of a customization, thereby consists of a product or system, and the Customized Carrier Board here is the mainboard with special purpose of customization, it comprises all external interface (SATA of user's request, PCIe, USB, Power, Audio, Video etc.).In other words, this is the integrated single board computer of a kind of height, is particularly suitable for carrying out the customized industrial computing machine and solves scheme, is suitable at the single board computer of standard because of structure or owing to lack extendability and use unaccommodated the time.COM Express is the open international standard of PCIMG organizational structure, and PICMG is an association, surpasses 450 companies and jointly promotes the open architecture standard, mainly is at communication and application industrial and that receive.
COM Express standard is a standard that defines based on the x86 processor architecture, for x86 platform flexible Application is born in industrial embedded computer field.Now all be to adopt the CPU of Intel Company as primary processor basically, the x86 framework is a kind of sophisticated vocabulary processor architecture by Intel Company's exploitation, AMD and Cyrix company also developed the CPU of compatible x86 framework afterwards, present this framework has almost occupied all PC platforms and most server platform, the widely used Windows operating system of general employing, (SuSE) Linux OS also more often adopts on server is used.
There are following these deficiencies in existing this COM Express computer module:
1, the development and Design difficulty is high, needs BIOS, and the construction cycle is long, and chip replacement speed can not adapt to the long characteristics of industrial Embedded Application flexible design and the life cycle of the product fully than comparatively fast;
2, complex structure, CPU often will cooperate bridging chip to expand peripheral IO and bus interface, and the memory modules on the module, what define is that connector connects, so just increased the complexity of producing, wayward production cost and yield also affect the product shock resistance;
3, cost is high, just owing to the reason of complexity, R﹠D costs are higher, high performance CPU price is all higher in addition, also must add the bridge chip group, in order to satisfy the high integration requirement of COM Express, the complexity of circuit board also promotes greatly, the BIOS research and development all make whole cost of products can not be in any more;
4, power consumption is high, the CPU of x86 structure, high performance CPU often power consumption is very high, even the existing low-power consumption i7CPU that uses in COM Express module, power consumption also reaches 45W, if comprise cooperating bridge chip and memory modules and peripheral chip, whole board power consumption will reach more than the 50W again;
5, without technical grade, since the CPU of x86 mainly towards be the pc domain such as desktop, notebook, chip level all is business level, the product that does not have formal technical grade, the integrated circuit board of finished product need by experiment screening to satisfy the environment temperature need of work of technical grade;
6, without the local bus definition, industrial application has the non-standard peripheral hardware of a lot of customizations, and the local bus agreement is simple and reliable, can be used for a lot of the application;
7, in commercial Application, sometimes in order to guarantee Systems balanth and real-time, need to adopt vxworks operating system, the x86 platform application is got up more loaded down with trivial details.
Summary of the invention
The purpose of this utility model provides a kind of based on microprocessor embedded computer circuit board with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises microprocessor, connector, integrated circuit interface, the interchanger bus interface, local bus interface, the controller bus interface, USB interface and memory interface, the signal output part of described microprocessor respectively with the signal input part of described interchanger bus interface, the signal input part of described integrated circuit interface, the signal input part of described memory interface be connected the signal input part of local bus interface and connect, the signal output part of described interchanger bus interface respectively with the signal input part of described controller bus interface, the signal input part of described USB interface be connected the signal input part of connector and connect, the signal output part of described integrated circuit interface is connected with the signal input part of described connector, the signal output part of described local bus interface is connected with the signal input part of described connector, the signal output part of described controller bus interface is connected with the signal input part of described connector, and the signal output part of described USB interface is connected with the signal input part of described connector.
The beneficial effects of the utility model are:
The utlity model has following advantage:
1, the utility model can satisfy-55～+ 65 ℃ environment temperature job requirement;
2, can select flexibly VxWorks or Linux as operating system;
3, can require by vibration experiment: frequency sweep 5～200～5Hz, acceleration 2.5g, scans 3 times 12 minutes time;
4, the adding of local bus makes the utility model expand greatly the dirigibility of using, and can better control some external units nonstandard or customization;
5, the utility model overall power consumption is about 20W, far below the power consumption levels of prior art 50W.
