Description
Technical field
The invention belongs to the technical field of the identification of embedded multiple memory storage, particularly relate to a kind of hardware circuit of compatible polymorphic type serial storage, and the adaptive approach of compatible polymorphic type serial storage.
Background technology
The advantages such as storer is high with its integrated level, cost is low, easy to use, be applied widely in each electronic product and automation control area, its storage speed is fast, volume is little, low in energy consumption and cheap, can be electric erasable online, information can not be lost after a power failure, therefore, the first-selection of designer for extended storage capacity is become.
But, along with the development of science and technology, the arrival in chip speed epoch causes chip manufacturer to the continuous renewal of product, this just imply that the stopping production of a class memory storage model, when purchasing the serial storage less than in the past use in producing in enormous quantities, again printed circuit board (PCB) can only be made for new storer; This method has very large drawback, and again making printed circuit board (PCB) can delay tempo of development, reduces development efficiency, is unfavorable for market competition, strengthens production cost.
Although manufacturers' quantity of serial interface memory is in increase, but, once these equipment are arranged on a universal serial bus, also do not have a kind of general electronic method to identify these serial interface memory, this is problematic, because different equipment has different characteristics and may have different frameworks, if because memory device stops production, need similar model to replace, for running in systems in which, just must identify the memory device after replacement, carry out drive arrangements.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, a kind of hardware circuit of compatible polymorphic type serial storage is provided, it can save cost of development effectively, improve development efficiency, when not changing source program, not repeating to make printed circuit board (PCB), replaceable storer model, effectively improves the market adaptability to changes of electric equipment.
The technical scheme solved the problem is: the hardware circuit of this compatible polymorphic type serial storage, hardware circuit board arranges multiple storer connecting portion, the contact layout of each storer connecting portion is corresponding with a close memory pin layout, and the corresponding contact of the data of storer transmission pin connects the respective data transfer terminal of the master chip in described hardware circuit board.
The present invention adopts compatible circuit connecting mode, has effectively saved cost of development, has improve development efficiency, and when not changing source program, not repeating to make printed circuit board (PCB), replaceable storer model, effectively improves the market adaptability to changes of electric equipment.
Additionally provide a kind of adaptive approach adopting the hardware circuit of this compatible polymorphic type serial storage, master chip sends instruction to ask identifying information to the peripherals be arranged on universal serial bus, after receiving manufacturer identification code ID, by identifying that manufacturer identification code ID carries out device drives configuration.
