Purpose

Bootstrap knowledge of LLMs ASAP. With a bias/focus to GPT.

Avoid being a link dump. Try to provide only valuable well tuned information.

Prelude

Neural network links before starting with transformers.

Starlet memory map

00000000-04000000: MEM1 area (2 mirrors, 0x2000000 each)
	0000000-1800000: MEM1 (0x1800000)
	1800000-2000000: unimplemented / bus noise / junk? (looks like uninitialized memory but unwritable)

04000000-08000000: unimplemented, read as zeroes

08000000-10000000: register/SRAM area (8 mirrors, 0x800000 each)
	000000-400000: registers (4 mirrors, 0x100000 each) CANONICAL ADDRESSES: 0x0d000000 and 0x0d800000

Foreward

This document was originally written several years ago. At the time I was working as an execution core verification engineer at Arm. The following points are coloured heavily by working in and around the execution cores of various processors. Apply a pinch of salt; points contain varying degrees of opinion.

It is still my opinion that RISC-V could be much better designed; though I will also say that if I was building a 32 or 64-bit CPU today I'd likely implement the architecture to benefit from the existing tooling.

Mostly based upon the RISC-V ISA spec v2.0. Some updates have been made for v2.2

Original Foreword: Some Opinion

The RISC-V ISA has pursued minimalism to a fault. There is a large emphasis on minimizing instruction count, normalizing encoding, etc. This pursuit of minimalism has resulted in false orthogonalities (such as reusing the same instruction for branches, calls and returns) and a requirement for superfluous instructions which impacts code density both in terms of size and
