- TEXAS INSTRUMENTS生产的TMS320C6X系列数字信号处理器(DSP)和以前的DSP相比,由于先进的外部存储器接口EMIF的存在,可以和多种外围器件实现无缝接口,使用起来非常简便。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:采用免疫荧光双重标记法和相邻切片法分别用Avidin-Texas Red或FITC标记神经激肽B受体(NKR)样阳性神经元与c-fos阳性神经元,Bandeiraea Simplicifolia Isolectin-B4(BSI-B4)标记C纤维;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).
- 下文比较了数据交换所采用的各种技术 ,包括 DMA、全局存储器和 HPI( Host portinterface) ,并通过 TI( Texas Instrument)的典型芯片TMS3 2 0 C5 4 x着重讨论了 HPI接口的硬件结构与软件编程。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.
