For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of changeable computer system; Comprise controller, arithmetical unit, storer and IO interface, said arithmetical unit and said storer interconnected communication, said storer and said IO interface interconnected communication; Said controller respectively with said arithmetical unit and storer interconnected communication; Be used to control said arithmetical unit and storer, comprise that also one stores the nonvolatile memory (also claiming flash memory) that calculates the functional value of good various calculation functions through outer computer, said controller connects the said flash memory of control; Said storer is connected on the said flash memory, said flash memory also with said IO interface interconnected communication.
A kind of operational method of changeable computer system, it comprises following processing procedure: at first, controller is called in storer according to the needs of using with Function Y=f (x) from flash memory; Then, controller control arithmetical unit in storer, search respective function Y=f (x) according to Function Y=f (x) functional value to realize calculation function; At last, controller control IO interface is exported result of calculation from storer.
Further, in said Function Y=f (x), f (x) can be simple addition function, subtraction function, and perhaps complicated trigonometric function, in the exponential function any one also can be the combinations of multiple function.
Compared with prior art, the present invention has following beneficial effect:
1, can be provided with targetedly according to different applications owing to its computing function, so it can realize multi-purpose computer truly;
2, in the different operation phase of a program, calculation function can change at any time, and the overall process that it can the realization program be carried out all reaches efficient;
3, the function setting of arithmetic unit is to be selected and definition by user oneself fully, so can realize the efficient utilization of hardware resource;
4, owing to utilizing lookup table mode to find the solution various functions, so it is fit to do the calculating of complex mathematical function very much.This makes the traditional computer of its computing velocity far above equal technology.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of instructions, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
