Future, what changing all the time is embedded the evolution that systematic design environment can last. How should development environment change will undertake accommodative a change? The AtaKhan of Cypress semiconductor company has a few oneself viewpoint.
Embedded processor is already omnipresent now, almost all the device that uses phone can have embedded processor undertakes controlling to all sorts of application or (and) operation. Come more than 30 years, drop of the price ceaselessly and what the promotion with operation and control ceaseless ability drove these processor is prosperous with diversification.
Rub the pressure of Er law, competition and the ceaseless innovation that consume electronic equipment, make in soon, what we use daily is embedded processor will handle the processing capability like implemental equipment with the computer of the mainstream.
A lot of these innovation are promoted by the consumptive behavior place of people, human behavior meets those who ignore linear improve commonly, however the improvement of apt index level, because this urges a more function and more complex powerful system. because such, the consumptive electron equipment nowadays needs to deploy a 3 times MIPS of the processing capability at need embedded processor, go up the memory of G capacity, and ask through all popular communication the agreement joins come network, this requirement hardware (processor) , software development tool, operating system perhaps is compiled implement cannot give an issue. Additional, embedded architect itself also needs to understand newest hardware and software to use them to design the application that can commercialize.
However, the design ability that must see a real problem is the mankind " bandwidth " do not follow to go up far the degree that processing capability rises. Accordingly, complex spend rise make the design is adjourned, simple addition the issue that insoluble productivity promotes hand, no less than points out inside a few books in that way, sell well for instance long already composing " TheMythicalMAN-MONTH " one book.
At present the situation of the design
Design contemporary embedded the system is a complex much job job. The first pace is the action demand of the potential user that defines this product, know competitive foreground and answered program.
It is decision company next already the systematic norms that whether can be some resource reduced or correlation can realize, for instance software, tool, processor is mixed yuan of parts of an apparatus of other need. These jobs must be finished before job of actual soft hardware begins.
Once decide the early days job that the design starts was finished, most arduous hardware and software design were about to begin. Have representative, embedded the design includes 3 main module: Processing operation, number (periphery and logic) , imitate (pass feeling and) of pilot physics interface.
Most of a system is by above of 3 module all sorts of yuan parts of an apparatus is formed, these 3 module are undertaken contacting by the interface of hardware and software. Once a design is on software and hardware " finalize the design " , the word that wants a change again is very difficult and need expenses time and money, because the soft hardware between systematic module has each other,operate a gender.
