| 09:20.59 | eFfeM_work | afaik the arm on hawk does not have an fpu |
| 09:21.30 | eFfeM_work | and if you want to use the dsp, you need to write code for it, it is probably not worthwhile to use the dsp for a single instruction or so |
| 09:21.36 | eFfeM_work | too much time needed to setup things |

| 15:17.38 | mozmck_work | eFfeM: I was hoping that the linux floating point libraries would automatically use the DSP, I guess that's not so? |
| 15:19.13 | eFfeM | nope |

| 15:54.14 | eFfeM | mozmck_work: using the dsp is fairly expensive, they are two separate cpu's so data has to be transferred from the one to the other through memory |
| 15:54.29 | eFfeM | (the dsp cannot access the registers of the arm) |
| 15:58.46 | mozmck_work | hmm, sounds like that processor is not what I need them. |
| 16:00.08 | mozmck_work | I need a processor with fpu that is fast, and has fast IO and analog inputs that can run linux, for an embedded controller. |
| 16:00.25 | mozmck_work | them = then. |
| 16:19.54 | eFfeM | there are plenty of arm cores and some of them have fpu |
| 16:20.01 | eFfeM | not sure if beagleboard has fpu |

| 20:17.15 | w|zzy | eFfeM: The beagleboard has C64x+ DSP & video accelerator 430MHz; In the same processor with an arm cortex 8 |
| 20:20.05 | eFfeM | w|zzy: it is not the same processor, it is probably the same silicon, but they are two separate cores that are on the saem die |
| 20:20.38 | eFfeM | s/saem/same/ |
| 20:20.40 | w|zzy | Well ti calls it the OMAP 3530 Processor. |
| 20:20.47 | eFfeM | i know |
| 20:20.56 | eFfeM | i have one :-) |
| 20:21.15 | w|zzy | Ill be more formal next time :P |
| 20:21.54 | w|zzy | What kernel/rootfs are you running on your hawkboard? |
| 20:22.15 | eFfeM | http://focus.ti.com/docs/prod/folders/print/omap3530.html: it says explicitly subsystem |
| 20:22.46 | eFfeM | my hawk is sitting fairly idle at the moment but normally I run a kernel produced with openembedded |
| 20:22.59 | eFfeM | either something i made myself or an angstrom kernel from the autobuilder |
| 20:23.16 | w|zzy | Yup. |
| 20:24.32 | w|zzy | Got mine 2 days ago, i have only used the standard v3 kernel and an ubuntu rootfs. |
| 20:24.40 | w|zzy | Suprisingly easy to do that. |
| 20:24.54 | w|zzy | Setting up the build environment now. |
| 20:25.03 | eFfeM | it is a nice little board with a nice price |
| 20:25.37 | w|zzy | Sure seems to be. |
| 20:25.47 | w|zzy | The VPIF is pretty cool. |
| 20:26.07 | w|zzy | I also like the pin out header. |
| 20:26.58 | w|zzy | What tool chain do you use? |
| 20:27.13 | eFfeM | openembedded |
| 20:27.20 | eFfeM | www.openembedded.org |
| 20:27.31 | eFfeM | ls |
| 20:29.28 | w|zzy | I guess technically i am using OE through arago. |
| 20:30.59 | eFfeM | yes |
| 20:31.43 | w|zzy | As you see it are there any benefits to using a derivative project such as arago or angstrom? |
| 20:32.55 | eFfeM | i never played with arago, but generally it is a trandeoff between easiness to get something going and the amount of control you have |
| 20:35.23 | w|zzy | End of the day I should just run with it and if i hit a blockage work it out then. |
| 20:37.15 | w|zzy | My goodness.. OE is available as a debian repository |
| 20:46.55 | eFfeM | what do you mean? as a debian repository ,can you provide a url |
| 20:47.09 | w|zzy | have you used the codesourcery tools? |
| 20:47.19 | w|zzy | http://blog.leggewie.org/?p=39 |
| 20:47.29 | eFfeM | no, i build gcc with oe and use that |
| 20:48.23 | w|zzy | For a debian based system using a repository allows me to easily update when i do the rest of my system |
