New 800MHz XScale powered processor availableBy Chris Williams. Published: 16th Sep 2003, 19:21:53 | Permalink | Printable
IOP331 or IOP315 in Iyonix mark II?Intel appear to have recently sneaked out a couple of new and interesting XScale powered processors in their IOP range. The processor currently employed in the Castle Iyonix is the IOP321.
The IOP331 has a processor core speed of 800MHz, supports 133MHz 64bit PCI and supports up to 2GB of DDR RAM. The IOP331 is very similar to the Iyonix's IOP321 and is said to be "code compatible" with the IOP321. This means a 32bit RISC OS and third party software need no changes to run on the IOP331, however the pinout of the chip will most probably be different.
The IOP315 is more modest with a core processor speed of 733MHz, 133MHz 64bit PCI support and support for up to 12GB of dual ported 200MHz DDR RAM. The IOP315 is actually a two chip combination, bringing together the 80200 and 80314.
The two new chips do seem to show that Intel is still interested in XScale powered processors and enjoys touting the low power nature of the chips and the ARM compatibility. It also shows the range slowly creeping towards the 1GHz boundary which is what we all dearly want.
