Abstract
The utility model provides a DSP+ARM based mini-computer, which pertains to the technical field of computer technology, and comprises a DSP operation chip and an ARM control chip that are connected to each other via a dual-port RAM. Wherein, the ARM processor with a VxWorks operating system is mainly used for control, including serial port and function expansion, etc.; the DSP is mainly used for data processing; the two CPUs communicate with each other via the dual-port RAM. The two processors work simultaneously without mutual interference; therefore, the processing and control performance and speed are improved. Compared to the prior art, the DSP+ARM based mini-computer provided in the utility model has the following benefits: since two CPUs are employed, the calculation and control are processed in parallel, and therefore, the speed is improved, the operation time is saved, and the efficiency is improved.
Description
(1) technical field
The utility model relates to a kind of computing machine, and specifically a kind of will control separated with calculating, double-core small-size computer that control ability is strong, computing velocity is fast.
(2) background technology
At present, known computing machine is based on PC and SCM Based two kinds of conventional computer.Based on the computing machine of PC, be to be CPU with Intel X86, the periphery adds coprocessor, interface circuit compositions such as (comprising A/D and D/A, serial communication etc.), adopts higher level lanquage, and programming is than being easier to, and the producer of development is many, and technology is comparative maturity also; But interface capability is poor, needs more peripheral interface device to cooperate, and volume is big, is difficult for realizing miniaturization, and power consumption is also than higher.
SCM Based computing machine is mainly formed central processing unit by 51 series monolithics or 96 series monolithics that with Intel 8031 are core, and the periphery is equipped with a spot of interface device and forms.Its interface capability is strong, but its overall computational performance is poor, generally is 8,16, can't finish real-time calculating and high-precision control task, generally is used in the simple and easy control system more.
A new generation's small-size computer is representative with arm processor and DSP, can satisfy the requirement of high-performance and miniaturization.
Arm processor is supported real time operating system (RTOS), has simplified programming mode, supports advanced language programming, and is compatible good, is easy to expansion and upgrading; Arm processor possesses defeated I/O able to programme, serial line interface and various new standard interface, and interface capability is strong, is easy to expand various functions, but its computing ability is less better relatively.
DSP COMPUTER CALCULATION processing power is powerful, but its expansion and control ability relatively a little less than.
(3) summary of the invention
Technical assignment of the present utility model is in order to overcome the above-mentioned defective that existing small-size computer exists, a kind of double-core small-size computer to be provided.This computing machine is taken into account data computation and control function, is not only all obtaining reinforcement aspect control and the calculating, and supports multitasking.
The technical scheme that its technical matters that solves the utility model adopts is:
Based on the small-size computer of DSP+ARM, this computing machine comprises DSP computing cake core and ARM control type chip, connects by dual port RAM between two chips.
The interface circuit of above-mentioned DSP computing cake core at least with DRAM, FLASH, photoelectric isolating device, UART chip, 24 A/D in a kind of being connected.
The interface circuit of above-mentioned ARM control type chip at least with Compact Flash, PWM controller, 12 A/DLTC1857, photoelectric isolating device, transceiver in a kind of being connected.
The model of above-mentioned DSP computing cake core is TMS320C6713.
The model of above-mentioned ARM control type chip is PXA255.
Should adopt the ARM+DSP processor based on the small-size computer of DSP+ARM; Wherein arm processor adds vxworks operating system, mainly is used in the control aspect, comprises serial ports and function expansion etc.; DSP mainly is used in aspects such as data processing; Between two CPU by dual port RAM communication.Two processor is worked simultaneously, is independent of each other, and has improved processing, control and speed.
Small-size computer based on DSP+ARM of the present utility model compared with prior art, the beneficial effect that is produced is: adopt two CPU, calculate and the control parallel processing, speed is fast, has saved the time, has improved efficient.
(4) description of drawings
Accompanying drawing 1 is global schema figure of the present utility model and each several part functional diagram.
(5) embodiment
Below in conjunction with explaining below 1 pair of small-size computer work based on DSP+ARM of the present utility model of accompanying drawing.
As shown in Figure 1, the small-size computer based on DSP+ARM of the present utility model, two processors have been expanded functional circuit and use interface separately respectively according to different use needs and advantage each other.In order to handle communication and exchanges data between the two well, we have selected the dual port RAM form, and employing interrupt mode: PXA255 is mainly as gathering and control, the data that it calculates needs and handle are delivered to the dual port RAM the inside, send out then and interrupt giving DSP, tell to have deposited the data that need processing in the DSP dual port RAM in; After DSP receives look-at-me, extract the data in the dual port RAM, it is carried out computing, then new data is also sent into dual port RAM, PXA255 is given in concurrent interruption, and PXA255 carries out corresponding operation according to new data, has just finished once intactly communication between such two CPU.Adopt the dual port RAM form, be difficult for obliterated data, and communication speed is fast, the efficient height.
