Language-RAM This package provides a library (Language::RAM) and an interpreter (ram.pl) to emulate a basic "Random Access Machine". This computer model uses an assembler-like syntax and can be used to test simple algorithms for their complexity. SYNTAX There are four data registers (a, i1, i2 and i3), 1 instruction pointer (ip) and an unlimited (limited to your computer's capabilities, of course) data block s. imm: Number = \d+(\.\d+)? reg: Register = a|i1|i2|i3 mem: Value in s from fixed index = s[imm] mmem: Value in s from calculated index = s[i1|i2|i3 ((+|-) imm)?] INPUT/OUTPUT/HALT INPUT (imm|imm..imm): Store arguments in the following memory blocks OUTPUT (imm|imm..imm): Print values of following indices(after HALT) HALT: Stop program and print results ASSIGNMENTS reg <-- imm reg <-- mem a <-- mmem mem <-- reg mmem <-- a reg <-- reg CONDITIONALS jump imm: Jump to line imm if reg (<|<=|=|!=|=>|>) 0 then jump imm: Jump to line imm if condition is true ARITHMETIC a <-- a (+|-|*|div|mod) (imm|mem|mmem) INDEX-OPERATIONS i1 <-- i1 (+|-) imm i2 <-- i2 (+|-) imm i3 <-- i3 (+|-) imm COMMENTS Everything after "//" is a comment. COMMAND ADDRESS By default, a line's address is the line number. Prepend "imm> " to set the address of a line manually (e.g. "2> a <-- s // Command Address: 2"). INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Language::RAM You can also look for information at: RT, CPAN's request tracker (report bugs here) http://rt.cpan.org/NoAuth/Bugs.html?Dist=Language-RAM AnnoCPAN, Annotated CPAN documentation http://annocpan.org/dist/Language-RAM CPAN Ratings http://cpanratings.perl.org/d/Language-RAM Search CPAN http://search.cpan.org/dist/Language-RAM/ LICENSE AND COPYRIGHT Copyright (C) 2015 Fabian Stiewitz This program is free software; you can redistribute it and/or modify it under the terms of the the Artistic License (2.0).
