[答：Chengt]	请您具体说明是那种功能（英文名），实际上在Visual DSP++的help中您可以查到所有的调试功能说明．	[2006-3-28 12:01:10]

[问：realmanofpc]	请教BDTI是什么？
[答：Tonnyj]	BDTi is Berkeley Design Technology Incorporated BDTI performs independent benchmarking and competitive analysis on today’s DSPs and embedded processors Rather than using MIPS, MFLOPS, MMACs to judge the performance of processor, BDTI performs a detailed analysis and assigns a BDTImark which takes into account computational speed, memory bandwidth, instruction set, etc. BDTI has become a trusted name in the processor industry for benchmarking the true performance of a processor. BDTImemMark2000? The BDTImemMark2000? is a summary measure of processors’ memory efficiency on signal-processing applications. A higher score indicates faster memory performance. BDTIMark2000? BDTIMark2000? is a summary measure of processors’ signal-processing speed distilled from a suite of signal-processing benchmarks developed and independently verified by Berkeley Design Technology, Inc. A higher score indicates a faster processor.	[2006-3-28 12:03:14]
[问：ykh271828]	我看见ezkit开发版上面有一个usb的口啊？可以连到pc机上面在visualdsp++环境下面进行程序的下载和调试
