    This is hopefully the start of the rest of the licensees finally showing their implementations. Freescale's seems similar to the MBX Lite that Intel is providing to the Dell Axim.

    Though it's MBX Lite, it lists FSAA at zero cost.

    Is this an SoC?

    Seems like most every semiconductor uses ARM in this sector. Has SuperH been licensed out from Renesas to any of the chip companies?

    Off-topic: is this Pepperpad using an MBX Lite, Intel 2700G ARM R-S processor? If so, how well does it drive the 800x600 display?

    Yes. http://www.pepper.com/products/specifications.html

    800x600 shouldn't be a problem for the 2700G display pipeline.

    Strange whitepaper!

    They use overdraw to calculate the fillrate for the MBX. Didn't the MBX have an TBDR architecture, or not? ;)

    Also the bandwidth usage calculations seem to be an little bit odd IMHO.


    Otherwise I find it a little bit strange that they decided to use an MBX @ 66MHz but without an VGP, so this SoC is the second after Intel to use the MBX without the VGP. On the other side they use the "highend" MBX with 2xMSAA for free and up to 132MPixel fillrate instead of the MBX-lite inside the 2700G which is IMO good.

    ARM MBX models:

    MBX R-S = MBX Lite (no optional VGP)

    MBX HR-S = MBX (with or w/o VGP)

    From Freescale's whitepaper:

    On power consumption:

    ARM used to claim in it's very early whitepapers <0.5mW/MHz for MBX R-S at 275K.

    0.5 * 66MHz = 33mW
