| 09:14.20 | antaresX | hi all |
| 09:14.59 | antaresX | can somebody help for a question concerning CPU |
| 09:19.22 | madsy | antaresX: Don't ask for specific help. |
| 09:19.38 | madsy | Ask your question and let people answer if they feel like it. |
| 09:22.57 | antaresX | Thanks. I was looking on the net but hard to understand. What is the difference between CPU Intel and Pentium(R) Dual-Core CPU E6600 @ 3.06GHz and E2160 2Ghz. The first suppose to be better depends on the configuration ? |

| 21:04.33 | edboogie2k | hi guys. I am new to embedded development and was wondering. I am using a real time OS Keil RL-ARM on a 64 kb ram cortex m3 and I ported pnglite and zlib, is it a realistic goal to get PNG graph generation to work, for simple line graphs, or is 64 kb just too little memory to deal with graphics compression? |
| 21:05.30 | SpeedEvil | Line-by-line compression shouldn't be a problem. |
| 21:05.38 | SpeedEvil | As long as you have small dictionaries. |
| 21:06.05 | SpeedEvil | And again, if you can do the graphs on a scanline by scanline basis, it's not completely insane. |
| 21:06.08 | edboogie2k | ahh you mean repeating patterns in the binary of the graphics i want to compress? |
| 21:06.32 | SpeedEvil | no - as in if you can compress each line of the generated graphic seperately. |
| 21:08.35 | edboogie2k | ahh okay, what kind of library should i be looking for to actually draw the graphs using primitives like lines and boxes into a buffer, so far i only ported pnglite and its neccessary component zlib. |
| 21:09.09 | SpeedEvil | Dunno. |
| 21:09.15 | SpeedEvil | What sort of graphs do you want? |
| 21:09.25 | edboogie2k | simple line graphs of my sensor logs |
| 21:09.40 | SpeedEvil | Most graphics libraries will not be designed for minimal memory usage. |
| 21:09.51 | SpeedEvil | Hence they will assume you are drawing into a framebuffer. |
| 21:10.07 | SpeedEvil | And this gets nasty with 64K RAM |
| 21:10.15 | edboogie2k | yeah i am worried about finding something slim |
| 21:10.19 | SpeedEvil | What are you viewing the graphs with? |
| 21:10.41 | edboogie2k | i will allow people connecting to the webserver on my ARM to view the graphs embeeded into html |
| 21:11.26 | SpeedEvil | There is another way. |
| 21:11.31 | SpeedEvil | Don't. |
| 21:11.34 | SpeedEvil | Cheat. |
| 21:11.51 | SpeedEvil | http://code.google.com/apis/chart/ |
| 21:12.23 | edboogie2k | i'd like to generate the graphics on the device.. |
| 21:12.35 | edboogie2k | it would be trivial to generate the graphs on the client side in windows or linux |
| 21:12.40 | SpeedEvil | Why - given that you have a massively powerful browser? |
| 21:13.26 | edboogie2k | well what if my user has no internet |
| 21:13.35 | edboogie2k | this device is a sensor instrument |
| 21:13.51 | SpeedEvil | You can also put simple javascript charts in your device. |
| 21:14.02 | edboogie2k | ohh yeah? i didn't know that |
| 21:14.10 | edboogie2k | yeah i guess client side ajax type stuff |
| 21:14.15 | SpeedEvil | You just have it serve up the javascript too. yeah. |
| 21:14.26 | edboogie2k | yeah totally, maybe, thats not a bad solution |
| 21:14.38 | SpeedEvil | You can do charts, but I suspect to do it right, you will need to roll your own graph solution. |
| 21:14.50 | SpeedEvil | If you want to generate them as PNG or whatever. |
| 21:15.03 | edboogie2k | yeah totally, that might be nice to have in my toolbox for future APPS also |
| 21:15.12 | SpeedEvil | And making it generic is hard and annoying. |
| 21:15.25 | SpeedEvil | So you don't need to recode the library if you want to overlay three graphs. |
