Uses may highly effective dispose DSP again system’s dynamic load technology
Monday, September 29th, 2008 at 05:38 | No commentsCategories: DSPTags: DSP, dynamic loadShort Content: The new mobile communication market was the DSP technology has brought a series of new challenges. We may use the dynamic load technology to come effective addressing these difficult problems. Based on DSP (digital signal processor) the multi-purpose systems become day by day universal, in the wireless communication aspect is specially so. New generation superelevation performance DSP enables the base depot to be possible load bearing more pronunciations, the data as well as the video information channel, ... -
A perfect electric instrument data storage plan
Monday, September 29th, 2008 at 02:53 | No commentsCategories: StorageTags:Short Content: Not only the electric instrument takes measurement electricity consumption the instrument, the electric instrument precision with the examination chip precision related, has the very big relations importantly with its memory way, if examines the electric quantity data cannot the write store or the write store process makes a mistake, the electric instrument precision greatly reduces. The beforehand electric instrument data's memory way has 2 kind of choices: 1) with saves the EEPROM data; 2) uses the NVRAM ... -
Speech recognition control telephone plan
Monday, September 29th, 2008 at 02:53 | No commentsCategories: Communication NetworksTags:Short Content: 1st, synopsis< ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> This plan mainly adds the speech recognition recording and sending out module JT802 constitution by telephone chip CD802.
