Hardware system mainly consists of the following three parts:
( 1) Processor ( ARM9) Net operating systems, human-computer interaction aspects to complete control of the LCD display and read control keyboard control command; In terms of sculpture to finish on the original data read ( Through the USB interface) , pretreatment, analysis and calculation, and the calculated results is passed to the FPGA, and FPGA together complete control of the stepper motor.
( 2) FPGA: it receives data from the ARM interpolation arithmetic, and calculated according to the results of the interpolation control step-motor pulse number and time delay, finally complete control of the stepper motor to realize three-axis linkage of sculpture.
( 3) The human-computer interaction interface: human-computer interaction interface mainly includes keyboard and LCD. Almost all information about carving real-time display on the LCD; CNC carving and milling machine tool of the parameters such as pulse equivalent, and maximum speed and acceleration is set by keyboard, at the same time in carving the keyboard can also according to the need to enter special instructions.

hardware system hardware system's overall framework as shown in figure on overall framework. The whole hardware core for samsung $3 c2440 based on ARM920T processor, 64 mbsdram collocation as a system of memory, 128 mbflash as peripheral storage system, equivalent to a hard disk, in order to save all kinds of system programming and debugging download circuit when the power is cut off. Peripheral auxiliary equipment including USB interface: most of the processing files stored in the USB drive, need to be read from the u disk access, to save the FLASH storage space; Touch LCD: used to provide the system display and operation; Network interface: used to provide Internet service, convenient remote update program; Keyboard control: the operations necessary to provide processing, including points, start-stop control and deceleration, etc. Communicate with PC via a serial port or USB interface, which can realize online debugging or display real-time information in the upper machine. FPGA and ARM and bridge plate is linked together, to get the data from the ARM translates into control signal, through the bridge plate amplifying circuit amplifier, sent to the stepper motor control circuit.
