- Texas 美國德克薩斯州州名Tex.
- TEXAS INSTRUMENTS生產(chǎn)的TMS320C6X系列數字信號處理器(DSP)和以前的DSP相比,由于先進(jìn)的外部存儲器接口EMIF的存在,可以和多種外圍器件實(shí)現無(wú)縫接口,使用起來(lái)非常簡(jiǎn)便。The digital signal processor(DSP) of TMS320C6x of TI is simple to use compared to previous generations of TI DSPs in reason of a EMIF,which can be used as a non-slot interface to various external memory device.
- 方法:采用免疫熒光雙重標記法和相鄰切片法分別用Avidin-Texas Red或FITC標記神經(jīng)激肽B受體(NKR)樣陽(yáng)性神經(jīng)元與c-fos陽(yáng)性神經(jīng)元,Bandeiraea Simplicifolia Isolectin-B4(BSI-B4)標記C纖維;Methods: Immunofluoresence histochemical double-staining technique was used and colocalization of NKR was investigated through serial adjacent section methods. Bandeiraea Simplicifolia Isolectin-B4 (BSI-B4) labelled primary afferent C fibers and terminals in the superficial laminae of the trigeminal subnuleus caudalis (Vc).
- 下文比較了數據交換所采用的各種技術(shù) ,包括 DMA、全局存儲器和 HPI( Host portinterface) ,并通過(guò) TI( Texas Instrument)的典型芯片TMS3 2 0 C5 4 x著(zhù)重討論了 HPI接口的硬件結構與軟件編程。This paper makes a comparison among the following methods: DMA, Global Memory and Host Port Interface (HPI) and illustrates the hardware structure and software programming of HPI by an example of TMS320C54x, the typical chip of Texas Instrument.
