NAME

App::Scheme79asm - assemble sexp to Verilog ROM for SIMPLE processor

SYNOPSIS

use App::Scheme79asm;
my $asm = App::Scheme79asm->new(type_bits => 3, addr_bits => 5);
$asm->parse_and_print('(number . 70)');

DESCRIPTION

NOTE: this module does not do much at the moment.

SIMPLE is a LISP processor defined in the 1979 Design of LISP-Based Processors paper by Steele and Sussman.

The SIMPLE processor expects input in a particular tagged-pointer format. This module takes a string containing a sequence of S-expressions of the form (tag . value) representing a tagged pointer. Here the tag is either a number or one of several predefined values (see the source for a full list), and the value is either a number or another tagged pointer. These values are laid out in memory and a block of verilog code assigning the memory contents to an array named mem is printed.

More documentation and features to follow.
