The linker code to calculate the necessary auipc and remaining offset for a relocation and do something else when out of bounds, was written years ago, is two lines of code, and no doubt took less time than this conversation. I don't e

I know how ADRP operates. It's symmetric about the truncated PC. It's not symmetric about the actual PC. As I said in the last post.

Your figures seem a little off there. Yes, RISC-V is a little asymmetric, with the AUIPC being able to subtract exactly 2 GB from the PC or add 2GB-4KB to it, and then a jalr/lb/sb can subtract an additional 2 KB or add 2KB-1. But

If there is any assembly-language programming needed, or a code generator, then I suggest you start with the code for MIPSle. Many of the instructions and mnemonics are the same. The biggest differences are immediate arithmetic and load&#x2

This seems not correct to me. No one has made RVC "mandatory". For a start no one had any authority to do any such thing! Some people building Linux-capable processors decided to include RVC. Some people with Linux distributions (

I'll buy a LoweRISC as soon as they have something for sale (and I have one of the first HiFive1s). But at the rate both organisations are progressing I expect to be able to get a quad core 1.6 GHz 64 bit RISC-V "Pi-like" boa

The $3500 board is a lot, yes. There is also a $99 "Arty" board that is enough to run what is in the HiFive1, and I think even to add an MMU and run Linux. The $3500 one has enough space to do multiple cores, FPU and so forth as w

Only 2950 accounts with IDs from 1 to 6136 still exist, so there's been pretty much a 50% attrition rate at that level.

Every time you write an essay on this general topic I sit here wondering: Has he looked at Wellington, New Zealand? Beautiful city that people want to live in, lots of people living downtown, good university, a community with several very s
