[问:ykh271828]adi的ez-kit和stamp版的开发版在硬件上面有什么区别?stamp版可以通过usb或是以太网口或串口连接到visualdsp++上进行程序的烧写和调试吗?
[答:Xuek]It has small differents.
ez-kits has no USB port, so you should buy an extender board.
stamp board has no video and audio port. you should buy a video or audio
card.
Using stamp board is more easy to debuy uclinux.
Because ADI"s uclinux team is developing uclinux under it.
Visual DSP++ can debuy uclinux code. [2006-3-28 11:54:07]

[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.
