jleightcapnow reading: <i>Retrospective on High-Level Language Computer Architecture</i> [Ditzel and Patterson 1980]: a summary of failed design approaches for<br><br>- reduction of the semantic gap between programming and machine languages<br>- reduction of software development costs<br>- aesthetics ("esoteric")<br><blockquote>[High-level language computers] are aesthetically appealing to those not familiar with modern compiler writing technology. It is acknowledged that code generation may be simpler for a high-level language computer. What needs to be made more fully understood is that a high-level language instruction set does not eliminate the need for compilers, nor does it greatly simplify them. The need and complexity of compilers extends far beyond code generation. The amount of code necessary for preprocessing, lexical analysis, syntax analysis, assembly, optimization, loading, error detection, error recovery and diagnostics often dwarfs the part of the compiler concerned with code generation. The level of the target computer does not seem to have enough of an effect on the size of a compiler to warrant a totally new architecture.<br></blockquote>ref: <a href="https://dl.acm.org/doi/pdf/10.1145/800053.801914" rel="nofollow noopener" target="_blank">https://dl.acm.org/doi/pdf/10.1145/800053.801914</a><br><br>#compilers #computerarchitecture #forth #retrocomputing<br>

David JONES<p>So here's an idea i had that i'm almost certainly not going to do anything with (so you should). With AVX-512 we have 16 x 32-bit registers. Let's pretend that's a 16-deep stack. The permute instruction let us do a DROP and DUP (except, you'd probably want to ROLL them, but whatever). I'm imaging that top-of-stack would always be register 0; PUSHing something permutes all the registers 1-higher and replaces register 0. Now implement a FORTH.<br><a href="https://typo.social/tags/AVX512" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AVX512</span></a> <a href="https://typo.social/tags/FORTH" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FORTH</span></a></p>
Simon Forman<p>&gt; The whole point of <a href="https://mastodon.social/tags/Forth" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Forth</span></a> was that you didn't write programs in Forth you wrote vocabularies in Forth. When you devised an application you wrote a hundred words or so that discussed the application and you used those hundred words to write a one line definition to solve the application. It is not easy to find those hundred words, but they exist, they always exist.</p><p>~ Charles Moore</p><p><a href="https://www.ultratechnology.com/1xforth.htm" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">ultratechnology.com/1xforth.htm</span><span class="invisible"></span></a></p>
