1.我用18片ADSP21062做了一个系统，现在想升级到TS101是否方便、可行；2.我有ADI的ADSP21062开发工具（VisualDSP2.0，ICE）。请问：怎样才能升级到TS101的系统仿真、开发。 |
| [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与ＴＩ的６４系列ＤＳＰ相比， 有什么优势和劣势？开发工具和服务支持如何？ |
| [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. ADI has technical support in China and can
be contacted at the following :Toll-free number:

| [答：Ksri] |
You have a few options. 1. You can go for TS201 processor that
has 24Mbit of memory and 600Mhz processor speed to do your display
processing. However you might still want to add external SDRAM using the
onchip SDRAM controller of TigerSHARC processor.2. If price is a
major concern for this application, you can go for Blackfin processor that
is good for video display processing, but you need to add a lot of
external memory.If you can share more information about your
application and system, we can certainly help you. Our email is

[2003-7-24 10:56:57] |
| [问：68395] |
为何TigerSHARC处理器的功耗比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. |

ON-CHIP SRAM SIZE,DAM CHANNELS,DATA REGISTER,CIRCULAR
BUFFERS,难道这些指标也要小吗? |
| [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 |

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. |

请问在使用多处理器系统时，应该考虑的最关键因素是什么？ |
| [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 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. |

interfaces for some devices for audio applications. Hence, one can always
use Blackifn for Multimedia applications and processing.TigerSHARC
on the other hand is used for multiprocessing. TigerSHARC also has 8-bit
MACS for video applications. With 32-bit MACS you can use it for audio
applications as well.Please note that the DSPs are general purpose

请问你们的blackfin
,在应用于3G方面与TI的64xx相比有什么有点，有什么不足？ |
| [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. |

请问TS20X系列的DMA方式具体与TI的C6000的EDMA有什么区别，谢谢！ |
| [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 |

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 |

能否详细介绍一下该器件的后续研发情况及市场预测。 |
| [答：Ksri] |
TigerSHARC is a new product and has a long road map. We started with
180Mhz a couple of years back and moved to 300 MHz last year and now 600
MHz. In the future expect more TigerSHARC processors with more
speed, better peripheral sets and more integration.The market for
TS is great and more applications find TS a suitable processor |

| [问：xuenet] |
Could you compare TS101 with TI"s
TMS320C6416? |
| [答：Gerry] |
TS101 is 250MHz, TS201 is 500/600MHz. And provide twice 16MACs in one
cycle compared with C6416.TigerSHARC provide 3G communication
instruction which support both chip rate processing and symbol rate
processing, while C6416 only support symbol rate processing. |

| [问：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 |
| [答：Phil] |
Every system must include a TigerSHARC with ID set to zero
(0). |

operation. If you prefix the instructions with an "f" it becoems floating
point.No mode swithces. It is all part of the
instructions. |

TigerSHARC 处理器有成本优势么？谢谢！ |
| [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. |

TigerSHARC processor is a DSP. A traditional DSP has MACs, TS has MAC.
Tradition DSP has Circular buffer, TS has Circular buffer. Traditional DSP
has bit reverse, TS has bit reverse. Traditional DSP has hardware loops,
TigerSHARC also has hardware loops. Traditional DSP has parallel loads and
store, TS has the same.TigerSHARC on the other hand also has SIMD
mode and is a super scalar architecture where there is a lot of scope for
parallelism. |

我的电路板上有一个周期性的输入信号，是外板一上电就传给我的，通过PLD的处理作为TIGERSHARC（TS101）DSP外部中断IRQ0输入。可是一上电，DSP就开始缓慢升温到不正常的高温状态。或者一运行包含IRQ0中断响应程序立即升温到非正常状态并且不响应中断。当我不接这个信号时（仅仅翘起输入驱动芯片管脚），工作正常。所以我怀疑在DSP复位状态中就将该信号处理后输入DSP引起故障，故用DSP的FLAG信号作为对该信号的控制信号，结合DSP的复位信号，使得该信号产生的中断在DSP复位完成后，必须由DSP控制才可进入。经示波器观察确实实现。芯片不热了，但中断依然不响应。（程序经测试是正确的）而且如果在带电状态退出VISUALDSP++的EMULATOR状态，（即关闭VISUALDSP++）芯片开始运行储留在其内部的包含IRQ0中断响应的程序，芯片立即升温。但运行不涉及中断IRQ0的程序，芯片状态仍然挺好。对于该输入信号的控制，我觉得已经不会再对DSP复位有什么影响了吧？为什么会有以上的现象呢？（中断响应程序及其短小，仅仅对某一FLAG的TOGGLE）。 |
