With realizes based on the TMS320F2812 USB2.0 connection
Tuesday, December 8th, 2009 at 03:54 | No commentsCategories: Embedded systemShort Content: The TMS320F2812 digital signal processor is 32 fixed-point DSP controller chip which TI Corporation promotes, is one of present control domain most advanced processors. Its frequency reaches as high as 150MHz, increased control system's control precision and chip handling ability greatly. However, DSP and the outside high-speed service realizes is also in is researching and developing the stage, the domestic each DSP development version manufacturer is also at the security condition regarding this. In view of the fact ... -
TMS320F2812 and touchscreen signal procedure design_DSP, touch screen, TMS320F2812
Tuesday, December 8th, 2009 at 02:52 | No commentsCategories: Embedded systemShort Content: 1 introduction Since the 1960s, the digital signal processing (Digital Signal Processing, DSP) has become a mature technology day after day, and has substituted the tradition simulated signal processing system gradually in many application domains. The DSP technology and the equipment have nimbly, precise, the antijamming ability to be strong, the equipment size is small, the speed is quick, the stable property and easy to promote and so on merits. As the core controller needs to demonstrate take DSP ... -
TMS320F2812 in motor control system
Tuesday, December 8th, 2009 at 01:50 | No commentsCategories: Embedded systemShort Content: 1 introduction In the motor control domain, TI Corporation promotes 2000 series motor control DSP. TMS320F2812 belongs to the newest high-end product, suits the industrial control, the engine bed control and so on high precision application. At present 2000 series chips apply in the electric drive by TMS320LF240x primarily, applies TMS320F(C)28x to be quite few. But 28x has the more complete periphery control interface compared to 24x series DSP and the richer motor control peripheral device electric circuit, ... -
Designs and realizes based on the TMS320DM642 image gathering processing system_DSP, image acquisition, TMS320DM642
Monday, December 7th, 2009 at 23:58 | No commentsCategories: Embedded systemShort Content: Along with computer technology's fast development and market requirement's gradual growth, each kind of video information processing technology has played more and more vital role, widely applies in the network multimedia correspondences, the real-time monitoring system, aspects and so on high definition digital television. In video processing domain, because processes the data quantity is big, the algorithm order of complexity is high, therefore processes timeliness becomes a big difficult problem. In this case, multimedia processor TMS320DM642 by its ... -
Based on TMS320C6000 DSP FIFO-network data transmission_DSP, fifo, TMS320C6000
Monday, December 7th, 2009 at 18:11 | No commentsCategories: Embedded systemShort Content: The networking in the rapid development, network interface's performance unceasingly is also enhancing. Because the ethernet connection cost is low, the speed is quick, the performance is good, the development is convenient, more and more data acquisition system uses the ethernet connection to take the final data output and the control port. But in corresponding embedded system domain, more and more chips, from monolithic integrated circuit to DSP, also gradually starts to support the ethernet connection. The TCP/IP ... -
The embedded fingerprint processing module design with realizes_DSP, TMS320VC5402, fingerprint
Monday, December 7th, 2009 at 17:09 | No commentsCategories: Embedded systemShort Content: First, introduction Because human body's fingerprint has the long-term invariability, the stability and difficulty with forge and so on characteristics, already became the modern biology recognition technology the first choice, automatic fingerprint recognition system (AFIS) is refers to the collection fingerprint image gathering, to distinguish and to give the identification authentication result is the system which a body's software and hardware unifies. At present, the automatic fingerprint recognition system may divide into two kinds: One kind is gathers the ... -
ARM CPU CS89712 and C5510 DSP connection design_DSP, ARM, CS89712
Monday, December 7th, 2009 at 08:28 | No commentsCategories: Embedded systemShort Content: 1 introduction At present the embedded system widely has been applied high-end equipment domains and so on electronic products domain and wireless communication, network service. 32 ARM embedded processors have the high performance, the low power loss characteristic, the DSP chip, because the function is formidable, in addition the connection is convenient, the software available resource is rich, the programming is convenient, the stability is good, the precision higher merit, the application is also getting more and more widespread. ... -
DSP C language foundation main point_DSP, C language
Wednesday, December 2nd, 2009 at 04:58 | No commentsCategories: Embedded systemTags: C language, DSPShort Content: The beginning of the year to the present, contacted DSP already a half year, as a result of the company nobody instruction, did such for a long time has not had any big achievement, also took many tortuous paths. Before makes the monolithic integrated circuit to arrange some procedures with C, thought personally is alright. Now looks like also is only in ate before inside the school some C language superficial knowledge initial capital, in addition some on-line ... -
The CCS programming crosses the threshold_DSP, CCS
Friday, November 27th, 2009 at 15:09 | No commentsCategories: Embedded systemShort Content: TI Corporation has provided the highly effective C compiler and integrated development environment Code Composer Studio, studies C6X the programming should from to study CCS the use start. First installs CCS, CCS the installment to have the detailed explanation, and has brief Quick Time multimedia to introduce, regarding has not purchased CCS the user, may obtain 30 day-long proof edition from TI place (not to have hardware simulation function). Before using CCS, to need to carry on the ... -
