Re: Is ARM doomed?

DavidS, I do think that the people that did Risc-V and AARCH64 must have been talking to each other, they both came up with ISA's that are a lot more difficult to decode than ARM is. Please pull up the RISC V Instruction Set Manual https://content.riscv.org/wp-content/uploads/2017/05/riscv-spec-v2....

Re: Is ARM doomed?

I most definitely hope that RISC-V becomes successful. Not because I like the ISA, I do not. I hope that it does well because it is a good open alternative to other CISC designs, not so much an alternative to RISC designs in my mind. It is unfortunate that ARM dropped much of the RISC ideology start...

Re: Is ARM doomed?

RISC V is a very strange ISA, with many things that do not quite fit the way of coding that we have come to know in the RISC world. Even the instruction word is not very consistant among itself. That's a shame. One of the changes for Aarch64 from ARM was to make the fields in the instruction word m...

Re: OpenSCAD

This is enough of an issue that I am actually tempted to break my long standing rule of no JS. I do not like to admit it though at least OpenJSCAD works out of box (though a lot slower than OpenSCAD on the same HW).

I do hope it is not time for me to learn Java Script.
