问:请TI公司的DSP技术专家GeorgeShen先生和AccountManager王剑先生做一下自我介绍。(10:36:50 AM)答:大家好，这里是TI公司的盛戎华、王剣，很高兴和大家一起讨论TI的DSP产品。Good morning! Hello this is George Sheng, an Field Application Engineer of TI China, BJ office, and Wang Jian, Account manager of TI China, BJ office. We are glad to have a chance to answer your questions about TI's DSP.问:Dear Sir, Could U introduce the future usage of DSP simply? And, howcan i learn DSP quickly? Thank you (10:37:15 AM)答:Thanks for your question. We have entered internet era. DSP will beused in digital signal processing such as, communication, modem, real time control, digital image ... You can learn such as knowledge in some books which are published by universities.问:请问什么是数字信号处理器DSP？(10:38:06 AM)答:DSP是一种类似计算机中CPU的处理器。但是它具有更快的处理速度和对某些特殊问题的处理能力。所以它适用于高速和实时问题的处理。问:C6712怎样访问I/O空间？(10:39:41 AM)答:Acturally, C6000 have only one memory space, include Data and Progmemory. The I/O also be mapping to memory space, can be accessed through EDMA and EMIF bus.问:TMS320C6712的32位浮点特性与以往推出系列相比，有哪些优势，可提供哪些性能，存在哪些不足？(10:42:21 AM)答:It support IEEE_SP32 and IEEE_DP32 and IEEE_DP64 float_point. Comparewith C3x, it has strong C compiler and also good development tool CCS.问:What is the budgetary pricing? (10:43:14 AM)答:The price is less than $10.00.问:TI能否尽可能将闪存集成在今后的DSP产品中，以减少外设和提高线路精度？(10:43:22 AM)答:TI具备将FLASH集成到DSP中的能力。但是不同的用途有不同的要求。所以我们针对用量较大的客户会进行集成以满足客户要求。问:Is 6712, 6711 and 6701 all pin compatible? (10:45:39 AM)答:Yes, they are all compatible.问:以5409为例，很多DSP产品在使用前必需进行内存分配，该工作目前由用户自己进行，虽提供了很大的灵活性，但对经验较少的人来说会耗费很多不必要的精力，所以请问TI能否在发货时就为芯片提供标准的配置文件？(10:46:15 AM)答:DSP link comand file is effective tool to manage DSP memoryconfiguration to improve system feature. DSP BIOS has visuable tool to deliver the function.问:请问DSP与CPU、MPU有什么区别？(10:47:03 AM)答:The structure of DSP is difference from CPU/MPU. In DSP, there aredifferent memory for data and instruction. And it focus on computing not flow management.问:请问它的特性除了有100-MHz Clock Rate和600 MFLOPS外, 还有什么特点呢? (10:49:53 AM)答:与6711相比，除这些特点外，6712还有较的的价格。问:TI能否为其DSP产品提供更加灵活的外设以满足多样的应用需要？(10:55:06 AM)答:Yes. In C6000, we have peripherals as these McBSP, HPI/ExpensionBUS/PCI,EMIF(can connect with SBSRAM, SDRAM, Async RAM flush ROM SRM), DMA/EDMA, timers etc.问:请问"数字信号处理器"的对象是什么？(10:58:14 AM)答:wireless communication, broadband internet access, image process,modem, disital motor control ... We believe it can be used in every internet action, every bit.问:TI的DSP产品的C代码编译效率低，常使开发者感到其结果不能达到预期，请问TI有无应对之策？(11:01:19 AM)答:The C6000 C compiler performance can reach 70-80%. This is justbecause the from the beginning time of C6000 core design, the RISC like structure have make the C compiler and optimizer can be easy design and reach high performance. That means the C optimizer is begin from basic hardware design. So the question is true for other DSP, for C6000 good C compiler is our strong point.问:TI公司的DSP有什么特点？即在处理速度、存储量、接口以及软件编程等方面有什么特点？(11:15:59 AM)答:For C6000, it is the most advanced DSP, our C64x can run at 700Mhzto 1.1Ghz, the memory space for C6000 can be 32 bits wide. And we have DSP/BIOS which is industry proved and free real time kernal can help engineer design more easy and focus on their application.问:DSP是不是扩大了功能的单片机？(11:46:40 AM)答:No.问:在未来，DSP是否有代替CPU的可能？(11:50:25 AM)答:TI believe that in the coming internet era, many application engineswill be driven by DSP such as image, communication, digital consumer appliances. CPU can be used as a controller, DSP will be used for specific functions.问:DSP 与 FPGA 的区别？性能及用途方面。(11:59:00 AM)答:DSP can be reprogramble offline and online, have more flexible thanFPGA.问:请问贵公司的6712可用在民用的哪些方面？(12:01:39 PM)答:C6000的特点是高性能，应用比较容易（用C开发），如用在应用复杂的场合, 会很有优势，如网络相机，用户端网络加密等。问:TMS320C6712高频特性适用于跳频、扩频的哪些具体应用？是否适用于蓝牙技术？(12:13:36 PM)答:跳频、扩频 Yes，蓝牙技术 No because its power consumption.问:除了众所周知的DSP外。TI在模拟器件领域最关心的方向是什么？(12:17:49 PM)答:TI is taking effort for provide all kinds of analog products portfolio.In addition, we are going to publish more than 400 new products in 2001.
