德州仪器（TI）DSP电路板的硬件设计和系统调试Texas Instruments

简介：德州仪器（TI）DSP电路板的硬件设计和系统调试

问：DSP的程序编写用汇编好还是C好？
答： You can use C coding and compiler for assemble code to do the function verifiction, for better code optimize, you can modify with assemble code.

问：5402的接口电压是3.3V,内核电压是1.8V,当与5V工作电压的外围电路接口时,需要进行电平转换,请问目前有没有与5402兼容且工作电压是5V的DSP?谢谢!
答： 有，TMS320UVC5402

问：why I can not use the memory with address 0x0080A800-0xFFFFFFFF in C30? but it is the extended memory according to its User"s Guide.
答： It is OK.

问：关于TMS320VC5402 bootloader 的问题:
仔细阅读了 c5402的 bootloader,但是没有关于HPI的引导方式的详细介绍,所以希望你们能给个例子,即如何写将.OUT 格式的文件转化为.hex格式的cmd文件,不知道是否可以
答： 你可以下载TMS320VC5402 BOOTLOADER的一篇文档，写的挺清楚

问：我正在使用TMS320VC5402，通过HPI下载代码，但5402的内部只提供16K字的存储区，请问我能通过HPI把代码下载到它的外部扩展存储区运行吗？
答： 不行，只能下栽到片内

问：There are 2 McBSP"s in "5402. How can I control 4-way low-speed data input,e.g.,voice ?
Thanks
答： I don"t understand your question. Please contact TI.

问：1.Which models are better(high performance and low price),when i design a biometric-image processing system.
2.If i had selected certian model TI DSP, what tools are need but css.
答： 1. You can use c54x or c55x platofrm for the biometric system. if need more performance, you cna use c6x series.

2. EVMs and also XDS510 emulator.

问：Does TI DSP chip have FPGA function?
答： If you are talking about emulation function. My answer is YES.

问：1　3.3V的DSP能否与5V的A/D相连接
2　目前设计一个浮点的系统采用哪一种芯片较好
答： 1.  No. You need a level shifting IC between them.
2.  If you need an high performance floating DSP, I recommend C6000. For more details, you could refer to the DSP selection guide

问：请问，DSP在与前向通道(比如说AD)接口的时候，布线过程中
要注意哪些问题，以保证AD采样的稳定性？
答： 模拟地和数字地分开，但在一点接地。
