    for one thing because ram has much less headroom for OCing, you can consider them as already being "overclocked". mobile cpus are often underclocked for saving on battery power which does not matter much because RAM is already so slow compared to the CPU that in most applications (not...

    Sdio Ram Drive

    25MB/sec with no seek time is quite good, normal HDD have long seek time and swaping in/out causes a lot of seeking so it wouldn't be so slow compared to HDD. I've been trying to download the new xilinx webpack and toy with the idea (got 64MB DDR on the dev board) but their download server cuts...

    Next Generation Pandora

    I'm not saying its a good idea, but its not so ludicrous, this has been done before: http://en.wikipedia.org/wiki/Commodore_128 two completely different CPUs (65xx, Z80) sharing the same hardware. they didn't run at the same time but could "task switch" back and forth between the CPUs. and...

    Sdio Ram Drive

    not constantly hitting, but regularly on application switches is a good probability. my laptop in 2001 was a Celeron 650Mhz, 192MB of ram, running Mandrake Linux + KDE, pretty close in power to the Pandora. I could get work done really well even tho the swap would easily go up to 512MB usage...

    2 Players Simultaneusly? -Nds Question

    the DS still has a 16bit bus to main memory so code density still help, altho the cache makes the difference less pronounced. code size depend on the game type and how the game was developed, rush jobs using 10 AI programmers fresh out of school in large game studios will create a huge amount...

    Video Cable/connector

    nice, I did not know the plug was TRRS and already had the mic input. makes it easier to do a hardware mod: 1 trace cut on the mic signal, wire a hardware switch and a few thin wires. you could switch between mic+audio and video+audio, you're unlikely to be using both at the same time ...

    Sdio Ram Drive

    that's what I'm saying: they don't seem to make fast serial rams. all the serial ram chips I've found were small and designed to be connected to slow (~16Mhz) micro-controllers / SoC. a large 133Mhz serial-accessed SDR DRAM would give a decent 16MB/sec (not counting overhead or a self-clocking...

    2 Players Simultaneusly? -Nds Question

    most of the code on DS is Thumb by default (although the ratio of what gets executed vs space is different) the AI code is likely to be executed once per frame and/or be so large as to not fit in the cache anyway so the smaller size makes Thumb a better fit. the type of operations for AIs also...

    Sdio Ram Drive

    it'd be faster than erasing a sector, I tried to put a swap on an SD card for the heck of it, for very light work on a fresh card it was ok, but SD controllers have an internal buffer and making a bunch of IO quickly saturates and stalls on sector erase. and as for "ultra fast" != "serial" ...

    2 Players Simultaneusly? -Nds Question

    I was not counting on running under Linux for this, or you'd need a kernel module to have fast aborts processing, nor using OpenGL ES drivers, direct hardware access to the GPU, textures, and framebuffer is needed for rendering 3D and 2D stuff efficiently. (OpenGL is very bad at texture updates...

    Sdio Ram Drive

    topic for hardware gurus (and hobbyist wannabes like me) : I was thinking of ways to increase the ram for fun (other than duct-taping a swap space usb HDD under it, and/or destroying a flash SD card with repetitive swap writes). there are RAM-based IDE and now SATA "harddrives"...

    Video Cable/connector

    I'm curious how much would it raise the price to have both the custom connector with extra stuff (which is really nice to have), and the TRRS plug (replacing the TRS headphone one while still being compatible). if the OMAP3 hardware support mixing both signals internally with a software control...

    2 Players Simultaneusly? -Nds Question

    the cpu emulation speed isn't a problem (64Mhz ARM9 -> 600+Mhz ARM Cortex, you don't need to emulate the ARM7 just simulate the IPC), but the DS hardware is insanely complex. games using "Nintendo Wifi Connection" would be easy to connect with as they use standard internet protocols and are lag...

    New (Crappy) Video

    the functionality looks nice and its pretty fast. hopefully V1.0 will have a sharper UI :lol: tried "insmod focus.ko" ? :P I know digicams have trouble focussing in low light, maybe you can try starting the recording with the lights on so it locks focus and turn them off afterward ? c'est...

    This Is Why We Do Not Have Vga On The Pandora!

    you can't feed a VGA monitor at 30Hz directly, its 50-70Hz depending on the resolution. outside of that the protection / power saving will kick in on just about any CRTs less than ~15 years old and any LCDs, besides, you'd get huge flickers if it worked. if you mean by using a USB VGA adapter...

    Video Cable/connector

    to get composite from s-video you just mix both luma and chroma signals by connecting the wires. (with an optional ~3.5Mhz lowpass filter on the luma feed before mixing)
