I was speaking to Prof. Veeresh Deshpande from IIT Bombay about optimal hardware system design for LLM inference. I explained to him how my ‘perfect’ hardware should have equal number of floating point operations per second (FLOPS) and memory band...

In this post, let us add procedures to our compiler. Procedures or functions are a basic building of any language – especially so with lisp because it was highly influenced by Alonzo Church’s lambda calculus. Lists and procedures/functions togethe...

A lisp is not a lisp if it doesn’t support lists! In this post, let’s implement complicated data structure like lists, strings, etc. These data structures don’t fit in single word like they did for integers, characters and others from our earlier ...

In this post, let’s implement conditional expressions: (if test conseq altern). This is simple to implement at assembly level. We need to employ two labels to transfer control to conseq or altern based on whether test is true. In scheme all values...

In the previous post, we added stack to our implementation of scheme. This allowed us to store intermediate results and therefore binary primitives like (+ a b). Since we now have stack, adding local variables should be straightforward. We will im...
