It really doesn't. Out of Order processors use reorder buffers, there are hundreds of them. The apple M1 has a reordering window of 500 or so. They also...Last edited by paulpach; 07 April 2022, 04:55 PM. -
They indeed lack any technical detail on their website. It seems their processor is a VLIW architecture, like Itanium 20 years ago.

They do allow using the latest. You can compile LLVM with the latest LLVM, but it is not required, you can use previous versions too.

Not exactly. A typical branch predictor is implemented as a cache. It looks like a hash table in hardware. Given the address of an instruction, it returns...Leave a comment:

There is: if every instruction can branch, the branch predictor would have to cache the path of every single instruction (this is not doable). Typical...Last edited by paulpach; 08 February 2022, 08:44 AM.Leave a comment:

It is a tradeoff.
Yeah, a predicated instruction is faster than a separate comparison and branch.
By removing the predicates, they save...Leave a comment:
