Blackfin 处理器：嵌入式多媒体处理器创新体系架构ADI

简介：

问：各位专家，你们好！我是ADI的新用户。我有两个问题想请教一下！
NO1：如何将自己的代码下载到FLASH中？
NO2：如果代码超过16K WORD，怎么办？
我是一名初学者，请尽量讲的详细一些，谢谢！
答： 1.In our EZkit we provid you a flash driver to program the flash. in your own system , if the flash is different with that in EZkit, you should write a flashdriver by yousleves refer to our flash driver source code. or use external flash programmer.

问：Blachfin 系列处理器都可以提供什么接口？
答： BF offers the following interfaces

SDRAM controller,
Timers
Watchdog timers
Real time clock
Serial ports - 2
SPI - 1 or 2 depending on processor
UART - 1 or 2
PPI - in 533/32/31

问：为什么在535中可以32位访问SDRAM，而在533中却变成了16位，这是出于什么考虑？在以后的产品中准备如何处理访问片外SDRAM的瓶颈问题？
答： BF-535 is a more expensive processor with more pin count. Som 32 bits external bus. In 533 it is a cheaper processor and less pin count. So  it has onyl 16-bit external bus.

The best way is to determine your applicatiuon code size and t

问：1.BK535如何设计USB接口，能否提供硬件电路图及固件框架？
2.如何将开发板上的SDRAM扩展成512M?
3.分别用C和汇编写程序，执行效率上有多大差别？

答： There is already a USB on BF-535 processor and there is no need to add any new USB. You can just connect the line driver and use is right away. For more information about using the USB and drivers, please visit our website at

问：完成1路MPEG4视频编码（352*288），同时完成网络传输等管理工作，应选用哪一款Blackfin处理器？
请推荐贵公司视频编解码处理方面的第三方合作伙伴。
答： BF532 is enough to complete this.

we have many 3rd parties, contact us to let us know which city are you in so that we can select the 3rd party for your easy.

问：请问在监控行业，硬件处理和软件处理最终会向哪方倾斜？ Blackfin 有哪些针对监控视频处理的特性。 与PHILIPS TRIMEDIA 比怎么样？
你认为TI的呢？
答： it will go to software solution, because it is flexible both in Architecture and system design.

Blackfin has special instruction for video.

we have better performance/price ratio compare to others.

问：贵公司是否提供软核？
答： No. ADI will not provide BF softcore at this point of time

问：我开发过218x和2106x系列的DSP，转入到Blackfin的开发容易吗？
答： very easy! ADI DSP is very easy to program, especially the asm lauguage is easy to understand. although the blackfin asm not compatible with 218x and 2106x, but also you can understand the blackfin when you met it.

问：请问Blackfin 处理器与其他公司的同类产品相比有什么优势？
答： Balckfin have intel MSA struction . It have DSP and MCU"s benifit. And  Blackfin is also fit in video application!
Any more questions or wanting more detail information about Blackfin pls visit our websit or mail to china.dsp@analog.com

问：How BF533 support LCD?
答： BF has PPI interface that is compliant with CCIR656 industry standard. You can connect LCD through this port and it should be seamless. With little gluelogic, you can accomplish connections betwen BF and LCD
