The G.726 pronunciation codec encoder-decoder realizes - en.51rd.net in SoPC
Friday, November 28th, 2008 at 18:55 | No commentsCategories: EDA/PLDShort Content: G.726 was ITU predecessor CCITT proposes in 1990 in G.721 and in the G.723 standard foundation about 64kbps the misalignment PCM signal conversion is 40kbps, 32kbps, 24kbps, the 16kbps ADPCM signal standard. The G.726 canonical algorithm is simple, the pronunciation quality is high, transforms after many times, the pronunciation quality has the guarantee, can achieve the network rank in the low bit rate the voice quality, thus obtained the widespread application in the pronunciation memory and the speech transmission domain. ... -
Realizes the multi-channel PWM output connection design and the simulation with FPGA
Friday, November 28th, 2008 at 03:55 | No commentsCategories: EDA/PLDShort Content: 0 introductions In many embedded system's practical applications, needs to expand FP-GA (the scene programmable gate array) the module, realizes CPU has the difficulty or realizes the efficiency low part to realize with FPGA, like the digital signal processing, the hardware digit filter, each algorithm and so on, or expand the I/O connection using FPGA, like realizes multi-channel PWM (pulse-duration modulation) to output, to realize the PCI connection expansion and so on. Through the reasonable system software and hardware function ... -
Based on FPGA and RTOS embedded symbol stream analysis design proposal
Thursday, November 27th, 2008 at 22:55 | No commentsCategories: EDA/PLDShort Content: Is expensive in view of the tradition digital video broadcast system symbol stream analyzer price, the use not convenient question, this article proposed that one kind of performance-to-price ratio good supplement design proposal, it take general FPGA and RTOS as the foundation, realizes the symbol stream analysis function based on the embedded hardware platform. In the article also elaborated symbol stream gathering, the symbol stream analysis and the information demonstration and so on many key technologies. The symbol stream ... -
In view of power design SDR solution
Thursday, November 27th, 2008 at 07:55 | No commentsCategories: EDA/PLDShort Content: Because looks like American union tactic radio system (JTRS) such plan, software definition's radio (SDR) was already confirmed. However, many questions are restricting the SDR widespread deployment seriously, the quite important question is a power. The power is in designs time each SDR subsystem's main consideration factor, because specially they must consume the hardware are radio than more powers. For example, to obtain the anticipated radio traffic to be away from (relies on link condition, typical value is ... -
Based on micro controller’s web server design - 51rd Chinese electronic net
Tuesday, November 25th, 2008 at 09:59 | No commentsCategories: SCMShort Content: Abstract: In recent years, along with the computer software and hardware technology's rapidly expand, computer's application oneself penetrated each domain gradually. Based on the WEB way and the SNMP way are the present two popular network management ways. This article introduced based on the RABBIT 2000 micro controllers, does not have operating system's embedded WEB server's design, and introduced based on the ARM7TDMI processor, and interface circuit's hardware circuit and software's design, this system cost is inexpensive, the user through the ... -
Carries GPS based on the vehicle the embedded Chinese obviously terminal design
Thursday, November 20th, 2008 at 03:26 | No commentsCategories: Communication NetworksShort Content: Abstract: This article proposed the embedded Chinese obviously terminal design proposal, involves one kind of vehicle to carry the satellite positioning system, carries the localization information which and the GSM/GPRS wireless communication function through the serial port correspondence using the vehicle the GPS terminal provides realizes the real time display localization information, the vehicle to carry functions and so on telephone, short information and voice prompt, achieves the man-machine interaction the goal, simultaneously unifies the central software also to be ... -
Meets the oral plate design based on VxWorks T bit router 2.5GPOS
Tuesday, November 18th, 2008 at 02:32 | No commentsCategories: Communication NetworksShort Content: Abstract: The Internet current capacity's swift growth, proposed to the backbone network transmission a higher request, we developed the total turnover rate to reach as high as 1.28T for this reason the bit high performance IPv4/v6 router. This router provides 2.5GPOS, the 10GPOS,100M ethernet, the 1000M ethernet, the 10GLAN ethernet, connections and so on 10GWAN ethernet, may facilitate the network. This article introduced briefly this router's gross structure, and deep research 2.5GPOS has met oral plate's design with to realize.Key ... -
I2C serial EEPROM application system’s toughness design
Tuesday, November 11th, 2008 at 22:49 | No commentsCategories: StorageShort Content: Introduction In the embedded control system, usually must use the nonvolatile storage. Regardless of being time the power failure the maintenance needs to preserve establishment, saves the important record, the reliable nonvolatile storage is one kind of ideal choice. Exterior the non-volatility saves uses the serial storage to realize frequently, the I2C connection product is the most commonly used one type. However, this product and other EEPROM memory are the same, when use also has some conditions to meet latent ...
