<i>Lanai is a simple in-order 32-bit processor with 32 x 32-bit registers, two registers with fixed values, four used for program state tracking, and two reserved for explicit usage by user, and no floating point support.</i><p>Might as well be a MIPS. The fact that Google has suppoedly developed its own CPU is interesting, but the architecture itself seems quite mundane.<p>Edit: comments on the article suggest it&#x27;s the Myricom LANai, a NIC embedded processor. Google may just happen have these NICs in their machines and want to write firmware for them.
