Hi,

Has somebody perform a speedtest between an IIM7000A (memory mapped) and an IIM7010A (I2C).
I do not need real speed, but if the 7010 is slow i go for the 7000

Frank.

Hello Frankeman,

Speed is a very relative word, I don't think the IIM7010A (I2C)
is slow. I have tested both the IIM7010A (I2C) and the IIM7000A.

It depends on what you want to do, personally I would use the
IIM7010A (I2C) for client based applications or small scale
server and the IIM7000A for server applications.
(note that this is an opinion)

If you visit a webpage using the IIM7010A (I2C) and you hit
F5 a couple of times then Firefox can show a Time Out page every
now and then. (specially with multi user)

If you really want power then the IIM7000A with ATMega128 is
nice. (The more flash the more HTML pages)


I see your location is Holland near The Hague if you want you can
test around with my TWI board.

Regards,


Barry de Graaff

Hi Barry,

I have both the 7000 and the 7010 module with the tcp-ip board here on my desk.
The tcp-ip board works with the 7000 perfectly, but to be honest i'am till this day to lazy to connect the 7010 and do a speedtest.
I tought maybe somebody else did the testing Wink
You did some test but measered no byte/sec i believe, maybe you can express it in a factor like 4/1 that would be enough for me.

Frank.

Hello Frankeman,

This is not as simple as it looks,

There are two options,

1. You send me some source code and I'll submit the load times here.

or

2. I can write a program this weekend that sends data
PNG files or something and see how the byte per sec are send.

The only problem is that I don't have and IIM7000 so I can't
compare the two.

Just tell me which one you prefer.

Regards, Barry

Hi,

If you would be so kind to write the software i will set up the hardware simultaneously so testing is very easy.
Maybe it is an opportunity to send the result to MCS so they can publish it.

Frank.

Hello Frankeman,

Here are the test results:

Parameters:
ATMega162 internal oscillator at 8 MHz with IIM7000a,
Using Firefox 1.5.0.4 with Fasterfox plugin 1.0.3

Sending 4170 in 2,484 sec (average of 3 loads)*

4170 in 2,484 sec equals 1679 bytes/ sec

*********************************************

ATMega32 internal oscillator at 8 MHz with IIM7010a,
Using Firefox 1.5.0.4 with Fasterfox plugin 1.0.3

Sending 4170 in 24,540 sec (average of 3 loads)*

4170 in 24,540 sec equals 170 bytes/ sec

*********************************************

* Note that in fact the speeds are a little bit higher
since I have not added the header bytes
(Content-Length: " + Str(filesize) + "{013}{010} etc...)
to the number of bytes send. But the times shown
is the time to send the data including headers.

Tests were performed using a peer-to-peer cable <1 M.

THIS TEST HAS NOT BEEN APPROVED IN ANY WAY
IT IS THUS TO BE CONSIDERED AS A VERY ROUGH ESTIMATION!

Best Regards,

Barry de Graaff

Hi Barry,

Thanks for the test.
It looks like the 7000 is 10 times faster than the 7010.
Maybe it is not a supertest but it will do for me.
170 bytes per sec is not very much, but the pcb will be must easyer to develop.

Frank.
