"A new startup out of MIT emerged from stealth mode today to announce that they're shipping a 64-core processor for the embedded market. The company, called Tilera, was founded by Dr. Anat Agarwal, the MIT professor behind the famous and venerable Raw project on which Tilera's first product, the TILE64 processor, is based. Tilera's director of marketing, Bob Dowd, told Ars that TILE64 represents a "sea change in the computing industry", and the company's CEO isn't shy about pitching the chip as the "first significant new chip architectural development in a decade". So let's take an initial look at what was announced about TILE64 today, with further information to follow as it becomes available."

Oh, ARM is fine. It's PPC that doesn't belong. I just don't like the basic design (too many weird instructions, no separate 32-bit and 64-bit operations, etc).
MIPS is my favorite, but x86-64 comes in a close second. It's so much better than people give it credit for. It's actually quite orthogonal in its addressing and operand modes. You get 8-bit, 32-bit, and 64-bit registers, along with 8-bit, 32-bit, and 64-bit operations. You get 8-bit and 32-bit immediates and displacements, instead of the oddly-sized immediates and displacements you usually get in RISC. Instructions that write to fixed registers and two-operand instructions suck a bit, but you can deal with both quite easily in the register allocator.
