| [问：hwj2008] |
Intel XScale平台上,I/O的存储频率最快能达到多少？ |
| [答：Choon_Yee] |
For the case of 80321, since it is sitting on the PCI-X bus the
throughput is about 1.06GB/s (theoretically) |
[2003-4-3 10:56:19] |
| [问：leefuyong] |
80321内部没有PCI桥，如果我们要在80321的PCI总线上接多个外设，我应该怎样设计，最多可以接多少外设。 |
| [答：Choon_Yee] |
it depends on application. If the 80321 is sitting at the secondary
bus of a PCI-X bridge, the number of loading depends on the speed, it can
vary from 9 to 2. |

采用Intel? XScale(tm)
I/O处理器有哪些优点？使用中应注意什么问题？如何解决？ |
| [答：
Tom_WANG] |
XScale technology has the benifit of "very low" power and high
performance. It compatible with ARM V5TE. At normal case, you can save
heat sink, fan,... cost on one system. Besides this, price/performance is
the leading at industry. Other benifits is the module related to IO, as
XOR, cache, ATU,.. to help customer resolve high demaning IO activity.
Since it is alreayd mature technology, we don"t expect customer developing
product has critical issue. We have dedicated TME supporting you |

| [问：dryyc] |
How about the performance of PCI bus when
xscale controls 4 PCI devices concurrent? And how to optimize performance
? Thank you. |
| [答：
Kee_Tiong] |
The PCI performance for XScale will depend on whether the IO interface
for this XScale is configured/capable of PCI or PCI-X mode. For 4 PCI
devices, a PCI-X bus can typically can go up to 100MHz, so for 80321 with
4 PCI devices, maximum performance should be able to reach
~800MHz.In order to optimize the performance, one of the easy way
is to make sure none of the 4 PCI devices will bring down the PCI-X bus to
PCI mode. |

| [答：
Tom_WANG] |
EID has the benifit of OS and application support due to X86
enviroment. at specifit NAS product, which, normally need networking and
sotrage management, and these two field could be waht IOP good at. e.g.
IOP has XOR, data cache and ATU help you handle huge IO activity. Though
X86 support general purpose demand. beside this, low power and high
performance is one velue to x86, IOP at 800MHz at 1.6V cost about .8W, in

80200 and 80312 combine togather as 80310. It has a PCI interface and
it is suitable in all PCI related application, mainly in Storage.80200
itself is only the core and it is more flexible. You need an FPGA to
interface with it and your application depends on what you have programmed
on your FPGA. |
[2003-4-3 11:39:14] |
| [问：xchjg] |
StrongARM是否要停产，另外XScale直接进行MPEG4可以吗？速度与功耗怎样？ |
| [答：
Tom_WANG] |
As far as I know SA110 already plan for EOL in the near future. Please
talk to Intel sales or disti on exact date. MPEG4 decoder can hook under
PCI. at seperate HW MPEG4 decoder, it could cost 4W more but will not
occupy CPU bandwidth. if you use SW to support MPEG4, I suggest to use IOP
at more than 600MHz. IOP at 600MHz cost only about .7W |

请解释一下“非透明”PCI桥接器和“透明”PCI桥接器的区别。 |
| [答：Kee_Tiong] |
Both transparent and nontransparent bridge allow designers to add more
PCI devices or more PCI option card slots than a single PCI bus can
support. However, non-transparent bridges differ from standard,
transparent PCI-to-PCI bridges by allowing independent mapping of primary
and secondary bus address spaces, a key benefit when local devices require
large address maps. Nontransparent bridge is normally used when there are
two processor domain one in the primary PCI bus while the second on the
secondary PCI bus. You can get more detail information at this URL

PCI-X和PCI的主要性能差别，请详细介绍一下。 |
| [答：Kee_Tiong] |
Besides the maximum frequency supportdifference between PCI-X (133MHz,
266MHz and 533MHz) and PCI (66MHz) there are also protocol differences
between PCI-X and PCI. PCI-X protcol use the bus more effiently e.g.
introduction of allowable disconnectin in PCI-X and attribute data
for transactions has improve the performance of PCI-X. E.g. for
the same frequency, there can be upto 34% improvement of performance of
PCI-X compare to PCI. |
