Pentium M for phones?

Intel’s plan to develop an x86-based system-on-a-chip line is well known – we reported on it way back in August 2005, for instance – but only now are details of the XScale replacement starting to emerge as the chip giant briefs potential customers.

The part’s codenamed ‘Tolapai’ and is based on the 32-bit Pentium M processing core. Add to that 256KB of L2 cache, an DDR 2 SDRAM controller – 400-800MHz memory supported – and an integrated South Bridge component that provides PCI Express connectivity, USB, SATA, Gigabit Ethernet, a cellular link and even RS-232, and you’ve got a list of the key functionality the SoC offers. The chip will have security algorithm acceleration hardwired in.
