1.我用18片ADSP21062做了一個(gè)系統(tǒng)，現(xiàn)在想升級(jí)到TS101是否方便、可行；
2.我有ADI的ADSP21062開發(fā)工具（VisualDSP2.0，ICE）。請(qǐng)問：怎樣才能升級(jí)到TS101的系統(tǒng)仿真、開發(fā)。 |
| [答：Ksri] |
1. It is technically feasible to upgrade your system with TigerSHARC. However you should note that TigerSHARC and 21062 are NOT assembly language compatible. Also, there are differences in the hardware interfaces between 21062 and TigerSHARC viz the link ports and external memory interfaces. One has to take care to redesign the same. However the approach of design is the same in both the processors.
2. You can use the ICE that you used in 21062 for TigerSHARC as well. For VDSP 2.0, you need to buy one for TigerSHARC separately. However the user interface and other features of VDSP in TigerSHARC are very similar to the VDSP of 21062.

TigerSHARC DSP與ＴＩ的６４系列ＤＳＰ相比， 有什么優(yōu)勢(shì)和劣勢(shì)？
開發(fā)工具和服務(wù)支持如何？ |
| [答：Ksri] |
TigerSHARC has all the advantages over the TI C64x. C64x is only at 600MHz and 720Mhz. It has only 4 MACs. TigerSHARC is also at 600 Mhz but has 8 MACs. Hence, C64x can do atmost 720 x 4 MMACs while TigerSHARC can do 600 x 8 MMACs. This means that TigerSHARC is much more powerful than C64x.
Also TS201 has 24Mbit of memory while the maximum memory of TI DSP is only 8 Mbit.

| [問：68395] |
為何TigerSHARC處理器的功耗比Blackfin要大的多？ |
| [答：Ksri] |
TigerSHARC power consumption will be more than Blackfin because it has more processing power. TigerSHARC can do 4800 MMAcs while Blackfin can do 1200 MMACs. TigerSHARC has more memory 24-Mbit while Blackfin has around 1 Mbit of memory. TigerSHARC has more pins and is a bigger package compared to Blackfin. hence TigerSHARC has more power consumption.
Please note that TS is designed for infrastructure applications that involve continous power source and hence power is not a concern. Blackfin is designed for power sensitive hand held applications. |

|
| [答：Ksri] |
When comparing the DSPs, a common benchmark that is used is MIPS. So, the definition of benchmark comes up now :
Benchmark is a figure that gives details of the processor performance.
So, when talking about MIPS, the figure should always be low because the lower the MIPS of an algorithm on the processor, the better it is. hence the lower the better.
Similarly, the onchip SRAM size , DMA channels registers are also important, but for example if registers are more, it is better because the registers are very important for performance.
Also, more memory is better. Hence, we need to understand the feature and decide whether smaller is better or larger is better |

當(dāng)用TigerSHARC用作系統(tǒng)設(shè)計(jì)時(shí),如何產(chǎn)生PWM模式波形? |
| [答：Ksri] |
In TigerSHARC, the timers are very simple. You cannot generate PWM output. But, one can always use the flag pins and generate the PWM output under software control.
The only catch in this case that the frequency of such a PWM will be very low since it will be under software control.
Essentially it is good to use an external PWM chipset. |

請(qǐng)問在使用多處理器系統(tǒng)時(shí)，應(yīng)該考慮的最關(guān)鍵因素是什么？ |
| [答：Steve] |
The key factors when considering a multi-processing system are:
Interprocessor communication bandwidth, (TigerSHARC supports high bandwidth thru two communication paths - the link ports and the parallel bus, both do not require any external logic)
Minimal Glue logic required between processors, (TigerSHARC requires none!)
Software complexity for controlling multi-processor communication. TigerSHARC family supports a unified multiprocessor memory space so processors can directly address each others internal memory and registers and can access a shared external memory. |

TigerSHARC處理器的開發(fā)環(huán)境支持C++嗎？我用來做視頻的編解碼夠用嗎？ |
| [答：Ksri] |
TigerSHARC is supported by VDSP++ 3.0 toolset. VDSP supports a subset of embedded C++ standard that involves class derivations and operator overloading etc.
Regarding the video encoder and decoder on TS, ADI has not implemented on TS. However, given the high MIPS of TigerSHARC, one can certainly impelement video encoder and decoder. However one has to take care of the size of the image because the MIPS will limit the size of the image. |

| [答：Ksri] |
A major advantage of Blackfin over c64x is
a) Power b) Price.
Blackfin consumes far less power than the TI part and is very very cheaper than the C64x.
The only disadvantage I see with Blackfin is in terms of the MIPS. TI C64x at 600 MHz offers 2400 MMACs while Blackfin at 600 MHz offers 1200 MMAcs. However in terms of price performance, Blackfin again wins over the TI C64x. |

TS201、TS202、TS203與TS101指令兼容嗎？ |
| [答：Phil] |
All of the members of the TigerSHARC family are assembly code compatible. The TS20x contain some instructions which TS101 do not have. These processors are not object code compatible so you will have to reassemble/recompile your source. |

| [問：ken23] |
請(qǐng)問這款TS20X是不是AD現(xiàn)有最高性能的DSP芯片？ |
| [答：Ksri] |
Yes. TS201 is the highest performance DSP in ADI family. TS201 is at 600 MHz with a communications Logic unit that greatly improves the performance of applications in CDMA base station turbo coding and viterbi applications processing. This also has around 24Mbit of onchip memory with 64-bit external memory interface to offer the maximum performance |

TigerSHARC 處理器于國內(nèi)同類型的處理器相比較，具有哪些方面的獨(dú)特優(yōu)勢(shì)？具體體現(xiàn)在那些指標(biāo)上？ |
| [答：Steve] |
The TigerSHARC excells at large signal processing tasks and supports scaleable multiprocessing, more processors can be easily be added to the system to increase performance. The TigerSHARC supports both 32-bit floating point data format and 16-bit fixed point formats. This allows a tradeoff of performance versus data precision.

請(qǐng)問TS20X系列的DMA方式具體與TI的C6000的EDMA有什么區(qū)別，謝謝！ |
| [答：Ksri] |
The basic job of a DMA be it on TS20x or TI DSP is the same - to transfer data from memory to another device without the core getting affected.
But the TS DMA implementation is very efficient. In the case of TS, when the DMA is happening, there will be no impact on the core, that is the core will not lose any performance. It has separate buses to transfer data from peripherals to memory.
On the ohter hand in TI DSP, when there is a DMA happening, there will be impact on the core to A certain extent that will definitely make the core idle in some cycles and hence the DMA will reduce the applications performance.
Hence, I would say that the DMA on TS is more efficient |

In EE-176,I found the timing requirement RESET PIN.(Power-up reset: after power-up of the system, and strap options are stable, the RESET pin must beasserted (low) for a minimum of 2 ms followed by a de-asserted (high) pulse of a minimum of 50 SCLK cycles and a maximum of 100 SCLK cycles and asserted (low) for a minimum of 100 SCLK cycles.) I want to ask how to realize it. |
| [答：Ksri] |
You need a programmable logic to implement the timing you need. Hence the problem. You can realize using a programmable timer, but a PLD is the best option |

| [問：sales] |
On ADSP-TS101S data sheet,Rev.A p.14,Tab.6,about the handing method of CPA and DPA signals,it said:'The CPA pin has an internal 500 ohm pull-up resistor,which is only enabled on the DSP with ID2-0=0. If ID0 is not used,terminate this pin as either epu or nc.if ID7-1 is not used, terminate this pin as epu'. I feel very confused when reading this explaination. Since 500 ohm pull-up will come into being when ID2-0=0,why shall we have to terminate this pin as epu or nc when ID=0 is not used as Tab.6 explained? I think it might be 'If ID0 is used,terminate this pin as epu or nc' ,is it right? Then I found EE-176,p8,table on how to handing CPA & DPA, it said, PU for ID7-1,Pu or NC for ID0, which is not accord with data sheet Rev.A |

TigerSHARC 處理器有成本優(yōu)勢(shì)么？謝謝！ |
| [答：Ksri] |
Yes ofcourse.
You can consider TS203 that is availble for just USD34.95. For this price you get 500 MHz, 4Mbit RAM onchip. This gives you a performance of around 1000 32-bit MMACs or 4000 16-bit MMACs or even 1000 floating point MMACs.
Hence, you can see that TigerSHARC has a tremendous price performance advantage.
For multichannel applications, this is still excellent because the cost per channel will come down. |

我的電路板上有一個(gè)周期性的輸入信號(hào)，是外板一上電就傳給我的，通過PLD的處理作為TIGERSHARC（TS101）DSP外部中斷IRQ0輸入�？墒且簧想�，DSP就開始緩慢升溫到不正常的高溫狀態(tài)�；蛘咭贿\(yùn)行包含IRQ0中斷響應(yīng)程序立即升溫到非正常狀態(tài)并且不響應(yīng)中斷。當(dāng)我不接這個(gè)信號(hào)時(shí)（僅僅翹起輸入驅(qū)動(dòng)芯片管腳），工作正常。所以我懷疑在DSP復(fù)位狀態(tài)中就將該信號(hào)處理后輸入DSP引起故障，故用DSP的FLAG信號(hào)作為對(duì)該信號(hào)的控制信號(hào)，結(jié)合DSP的復(fù)位信號(hào)，使得該信號(hào)產(chǎn)生的中斷在DSP復(fù)位完成后，必須由DSP控制才可進(jìn)入。經(jīng)示波器觀察確實(shí)實(shí)現(xiàn)。芯片不熱了，但中斷依然不響應(yīng)。（程序經(jīng)測(cè)試是正確的）而且如果在帶電狀態(tài)退出VISUALDSP++的EMULATOR狀態(tài)，（即關(guān)閉VISUALDSP++）芯片開始運(yùn)行儲(chǔ)留在其內(nèi)部的包含IRQ0中斷響應(yīng)的程序，芯片立即升溫。但運(yùn)行不涉及中斷IRQ0的程序，芯片狀態(tài)仍然挺好。對(duì)于該輸入信號(hào)的控制，我覺得已經(jīng)不會(huì)再對(duì)DSP復(fù)位有什么影響了吧？為什么會(huì)有以上的現(xiàn)象呢？（中斷響應(yīng)程序及其短小，僅僅對(duì)某一FLAG的TOGGLE）。 |
| [答：Eric] |
對(duì)不起，這個(gè)問題在短時(shí)間內(nèi)難以依據(jù)你描述的現(xiàn)象定位，能否在會(huì)后聯(lián)系我們的技術(shù)支持？ |

Now,I"am developing a system based CPCI and use four TS101s.I expand the four linkports(one for each ts101),but i can"t find a suitable interface (13 pins and for high speed transportation) |
| [答：Steve] |
Further research needs to be done to find a high speed low profile connector and cable to fit the CPCI for factor. We do not have a specific recommendation. |

用ad6634與TS101可以直接用LINK口對(duì)接。當(dāng)DSP改為TS201后，如何與AD6634的LINK口對(duì)接呢？ |
| [答：Phil] |
The AD6634 is compatible with the TS101 link ports but is not compatible with the TS20x link ports. The TS20x link ports changed substantially to support higher throughput.
Please check back with us later for new product announcements. |
