1.bf532 扩展16位程序flash的具体步骤 ？？
2.怎样修改flash download文件？来引导程序下载。
请您准备一下，我们有五十多个技术工程师和学生都很想听听。
我的联系电话： 0312-3335612
谢谢。 |
| [答：Rick] |
1〉BF532扩展16-bit flash 在BF533硬件手册上系统设计这一章节有详细说明

| [问：quinn.yang] |
请问多片BF561如何支持高速互联? |
| [答：Dan] |
The BF561 does not have an HPI (Host Port Interface). However, the BF561 is equipped with multiple high-speed peripherals that can connect to other processors.
The SPI port supports 33Mbps full-duplex communication. The processsor can be booted from a host via the SPI port.
The SPORTS (synchronous serial ports) support 66 Mbps and each are equipped with 2 data input pins and 2 data output pins. Data throughput through this port is 66Mbps * 4.
The PPI (Parallel Peripheral Interface) supports 133Mbytes/second. This can be connected directly to an FPGA, another processor or to a video encoder or decoder. Our internal applications team is developing an application note which describes the connection of the PPI to a host controller.
The external memory interface on the BF561 must always be the master so it cannot be used as a traditional host controller. With a small amount of logic or a dual-port RAM, this port can serve as a host port. |

AD公司的JTAG接口技术发展如何，请介绍一下。谢谢 |
| [答：Dan] |
While the boundary scan aspects of JTAG have not changed (and are not likely to change since this is an international standard), ADI has been adding more advanced JTAG debug features to our devices. Our current JTAG technology supports transfer rates of up to 50mbps. Our newer processors (like Blackfin) are equipped with a BTC (background telemetry channel) which allows the Blackfin to exchange information with PC in real time over JTAG without stalling the processor.
We are always exploring more advanced features for our future parts to increase the communication throughput between the processor and the development PC via JTAG (and future standards). We are also constantly enhancing new parts to support more advanced debug features in hardware. |

| [答：Dan] |
The PPI port supports glueless connection to multiple types of video encoders, decoders, TFT LCD, CMOS sensors, etc.
The schematics for our BF533 Ez-Kit Lite development board show a glueless connection for both a video encoder and a video decoder.
http://www.analog.com/processors/epManualsDisplay

&ContentID=32890&Language=English
There are also application notes on our website which show the connection between PPI and other types of video devices:
http://www.analog.com/processors/processors
/blackfin/technicalLibrary/#83
We have an A/V Expansion board for our Ez-Kit Lite development boards which has a glueless TFT LCD interface and Micron and Omnivision digital camera interfaces.
The maximum speed of the PPI is 66MHz. It supports glueless connection to 8,9,10,11,12,13,14,15 and 16-bit devices.
The unuesd PPI port pins on the Blackfin can also be used as GPIO when pins.

Blackfin处理器有DSP和MCU双核,对它们的编程或开发有何不同?是否和通常的DSP/MCU一样? |
| [答：Dan] |
The Blackfin only contains a single core - it is not like an OMAP which has a discrete DSP core AND a MCU core. Blackfin was designed jointly by ADI and Intel - the primary goal was to create a processor core which was equally capable of support DSP operations and MCU operations in a single core.
The Blackfin has many DSP features not found in a typical MCU such as a dual-MAC core supporting a wide variety of arithmetic operations in hardware, video-specific instructions, high performance memory and DMA system, and very high-speed peripherals, etc.
The Blackfin also has many MCU features not found in a typical DSP such as an MMU, excellent compiled code density, watchdog timer, real-time clock, RISC instruction set, etc.
For example, we have customers running ucLinux 2.6 kernel on Blackfin who are also performing real-time video and audio processing in the same core. This is possible because the Blackfin is very capable of both DSP and MCU operation. |

Blackfin处理器通用性具体如何？ |
| [答：Cheng] |
Ｂｌａｃｋｆｉｎ

| [问：freeqwg] |
请问ADI的blackfin与ti 的同类产品有何区别？ |
| [答：Dan] |
Blackfin is different from TI products because Blackfin supports DSP and MCU operation in a single core (i.e. can run ucLinux and real-time video on one Blackfin). TI makes DSPs only and uses DSP with an ARM processor to achieve the same result (i.e. OMAP).
A good quick comparison of performance between ADI cores and TI cores can be found at www.bdti.com. This is a 3rd party that runs benchmarks (FFTs, digital filters, vector ops, matrix ops, LPC, control code, etc) on all popular DSP cores and assigns a single score.
http://www.bdti.com/bdtimark/BDTImark2000.htm
The DSP performance of Blackfin is far superior to it"s closest cost and architecture competitor (C55xx family). Although the C64xx architecture is a much larger and more expensive architecture than Blackfin, the Blackfin processor competes very well against this too, especially when you factor in price and power consumption.
