| 01:09.45 | Exiles | ppc right? |
| 01:10.11 | LadySerena | I'd have to check. It might be. |
| 01:10.54 | LadySerena | mer ... the FreeScale website doesn't say |
| 01:11.07 | Exiles | I think it is |
| 01:11.32 | Exiles | it is |
| 01:11.41 | Exiles | http://en.wikipedia.org/wiki/Motorola_68060 |
| 01:11.52 | LadySerena | well, its not like I'm going to be running MacOS on it |
| 01:12.03 | LadySerena | most likely either FreeBSD or QNX |
| 01:13.04 | LadySerena | what I'm stuck on right now is a chipset |
| 01:13.23 | LadySerena | I've used Google and I can't seem to find a suitable chipset that I can buy fairly cheaply |
| 01:13.52 | Exiles | can't help there, sorry |
| 01:14.07 | LadySerena | grrr |
| 01:16.29 | T0mW | wow, motorola still makes that stuff? heh |
| 01:17.08 | LadySerena | Motorola? |
| 01:17.10 | LadySerena | er, no |
| 01:17.20 | LadySerena | the 68060 is FreeScale Semiconductor |
| 01:17.24 | T0mW | LadySerena: mot has always priced their stuff into the high-end of computing. One reason you don't see many designs around using them. |
| 01:17.43 | T0mW | freescale == motorola in drag |
| 01:18.10 | LadySerena | FreeScale == Motorola no longer does chips |
| 01:19.01 | T0mW | they may have spun off the division, someone else writes the paychecks, but the same people are working there and the corp mentality hasn't changed, IMHO. |
| 01:19.23 | T0mW | most of the people here are primarily ARM. |
| 01:20.10 | T0mW | I tried an XC68HC001 design years ago, then got a hard lesson as to what an "XC" designator meant. |
| 01:20.39 | T0mW | XC == experimental, they discontinued the chip 6 months into my design. |
| 01:20.50 | LadySerena | x.x |
| 01:23.19 | T0mW | last time I ever looked in their chip catalog. BTW, I did speak to the mot field engineer about it later, seems that Motorola was looking to sell that chip to Chrysler for their electronic ignition, when Chrysler changed their spec, the 68HC001 died, became the 68HC000 with an entirely different memory interface. |
| 01:23.51 | LadySerena | yikes |
| 01:25.01 | Exiles | I want a Cheap lowcost platform that runs linux |
| 01:25.05 | Exiles | embeded |
| 01:25.16 | T0mW | ARM |
| 01:25.36 | Exiles | so many ARM chips exist |
| 01:25.52 | LadySerena | so you're saying I should move the MP3 player over to ARM instead? |
| 01:26.11 | T0mW | shrug, unless you have deep pockets to do the dev work. |
| 01:26.41 | LadySerena | actually .... no, I don't |
| 01:27.07 | T0mW | Exiles: it is like this, you want to purchase an automobile, should you only have two models to choose from? |
| 01:27.43 | T0mW | Exiles: e.g. a family sedan or a two door coupe |
| 01:27.56 | LadySerena | hmm, well then, what I need is a processor that's fast enough to decode, EQ, and output MP3 in real-time, but slow enough to have a really long battery life |
| 01:28.48 | T0mW | I don't do MP3, I listen to FM radio, what's on is what's on. heh. |
| 01:29.20 | LadySerena | if I want radio I go to my car and listen to my XM, or I go to xmonline.xmradio.com and listen online |
| 01:29.24 | T0mW | some of the other guys here on the channel have done that stuff, but this is the weekend, most are not online. |
| 01:30.28 | LadySerena | ARM based mp3 players? |
| 01:31.45 | T0mW | sure, why not |
| 01:31.51 | T0mW | soft codecs |
| 01:32.33 | Exiles | pic mp3 players |
| 01:32.45 | Exiles | all depends on the features you want |
| 01:32.52 | Exiles | and your decoder chip |
| 01:33.00 | T0mW | people have been using 100MHz ARM720's with 11KHz bitstreams. Higher bitrates are very, 22KHz? 48KHz?, are doable with 200MHz processors. |
| 01:33.05 | Exiles | or you use a soft decoder |
| 01:33.47 | Exiles | takes much less power |
| 01:35.58 | T0mW | costs more though to use a hardware chip, doesn't it? |
| 01:36.53 | Exiles | depends on your design |
| 01:37.33 | LadySerena | I need MP3 decoding and an EQ ..... the decoder chip I've been eyeing doesn't have an EQ |
| 01:37.40 | T0mW | EQ? |
| 01:37.51 | LadySerena | but I CAN have the EQ if I go all-software |
| 01:37.57 | LadySerena | EQ == equalizer |
| 01:38.03 | T0mW | nod |
| 01:38.07 | Exiles | I've seen them with EQ's |
| 01:38.15 | LadySerena | mew? |
| 01:41.12 | Exiles | http://www.st.com/stonline/products/families/audio/audiodecoders/mp3/sta013.htm |
| 01:43.15 | LadySerena | that's the STA013 ... STA015 is sexier |
| 01:45.45 | Exiles | http://atmel.com/products/MP3/ |
| 01:49.01 | Exiles | Mhmmm |
| 01:49.09 | Exiles | single 1.8v chip |
| 01:49.13 | LadySerena | still no EQ support |
| 01:49.14 | Exiles | 100 pins |
| 01:49.28 | Exiles | one I'm looking at does |
| 01:49.36 | LadySerena | which one? |
| 01:49.50 | Exiles | AT85C51SND3 |
| 01:54.48 | LadySerena | geez, it seems like it'll do EVERYTHING. |
| 01:59.53 | LadySerena | k, so where does a CPU, memory, USB (to PC), network, and wifi come into the picture with this chip? |
| 02:00.08 | LadySerena | its not like an STA013 or STA015 where you simply feed it the data |
| 02:20.40 | *** join/#edev LadySerena (n=LadySere@24-55-117-193.clspco.adelphia.net) |
| 02:26.47 | Exiles | it will do everything you need |
| 02:26.54 | Exiles | read the datasheet |
| 02:27.07 | LadySerena | I was, until the power failure |
| 02:27.11 | Exiles | ah |
| 02:27.16 | LadySerena | which kinda knocked me offline |
| 02:27.21 | Exiles | yeah |
| 02:27.24 | LadySerena | and wiped my Firefox session-state |
| 02:27.42 | LadySerena | as well as just about every session-state that was on my computer and router |
| 02:27.49 | Exiles | last power issue here, power station for the local area was knocked out |
| 02:27.55 | LadySerena | power failures have a way of doing that, y'know? |
| 02:28.03 | Exiles | 10,000+ people lost power |
| 02:28.18 | Exiles | 150+ mile range at least |
| 02:28.22 | LadySerena | o.o |
| 02:28.31 | Exiles | part of californa and oregon lost power |
| 02:28.42 | Exiles | was a nasty outage |
