There was a Merced thread on this list a couple of months ago; I haven't
heard anything since.

Compilers must become more sophisticated to deal with more advanced
architectures. You can extract much more instruction-level parallelism

I have to agree with them, it's not RISC. It's VLIW, but they gave it a
marketing name, EPIC. There's been considerable VLIW research from HP,
Intel's design partner in the project. As for originality, well, it
seems many architectural tricks used in modern processors were first
used in the 60's or 70's. IMO, Merced has more originality than I've
seen in a new processor architecture recently.

Based on my experience, Microprocessor Report has amazingly accurate
descriptions of Intel projects. These two links provide very good
I'm sure Linux developers' experience with 64-bit Sparc and Alpha will
make the 64-bitness of Merced a very minor porting issue. As long as
somebody (HP, Intel) is nice enough to port gcc to it, I don't see how
any other operating system has much of an advantage over Linux :)
