In the News Well, you can classify this under the double-you-tee-eff header. There is rampant speculation in London's financial district that Apple may be planning to buy ARM, the processor design company many of us have a soft spot for. Shares of ARM went upwards quickly when the speculation started, making it the biggest winner of London's FTSE.

ARM is overrated

I think Texas Instruments with the OMAP 4 platform is the truly next generation of mobile devices.

*sigh*

Time to teach you how ARM works, and how SoCs work.

OMAP4 is a SoC, or System on Chip. A SoC contains one or more CPUs, all the I/O hardware, memory controller, various coprocessors that are needed, and sometimes (depending on purpose) a graphics controller. It's basically a complete chipset, just on one chip. (BTW, the difference between an SoC and a microcontroller is that SoCs tend to be more powerful, and have RAM and ROM off-chip, whereas microcontrollers have their RAM and ROM on the same die as the CPU and I/O hardware.

The CPU in the OMAP4 SoC is a dual-core ARM Cortex-A9 MPCore.

ARM doesn't make CPUs, they just design them, and license them to various companies at several levels - a company can license a design and use it as is, they can license a design and modify it, or they can license the architecture itself and create a new design based on that architecture.

In this case, TI licensed their Cortex-A9 MPCore for the OMAP4 SoC's CPU.

No disagreement the OPMAP 4 is a great processor platform, but so are also the NVIDIA Tegra 2. And more to the point, both are dual-core ARM Cortex-A9 based processors.

And I have no doubt that Marvell, Qualcomm, ST and Freescale have similar Cortex-A9 designs in the works. That is one of the things that make ARM so great. Another great thing is the scalability, from the high performance Cortex-A9 processors to the simpler cheap 20-100Mhz micro-controllers from about $1.
