People interested in VLIW (or EDGE, which sounds like VLIW but less strict) should also checkout the Mill architecture.
The designers claim a 10x speedup compared to existing processors. Their presentations are online on youtube, esp. the security related ones are amazing since they throw away alot of current design in x86/ARM CPUs.
- ahartmetz 8y agoThey claim a 10x power / performance advantage actually, what I gather is that it's supposed to be higher performance at much lower power. It isn't out of order and so it has to wait a long time in case of last-level cache misses. But it has insane throughput when it doesn't have to wait for memory. Most likely they'll mitigate the waiting problem by hyperthreading. GPUs do extreme hyperthreading to stay busy without any kind of out-of-order execution.
- deepnotderp 8y agoTo be fair, they've addressed memory access issues, and have proposed "deferred loads" (works well: http://people.duke.edu/~bcl15/documents/huang2016-nisc.pdf http://people.duke.edu/~bcl15/documents/huang2016-nisc.pdf) and other thus far unnamed techniques for mitigating it.
