Hi, We would like to announce Micro Python, an implementation of Python 3 optimised to have a low memory footprint.
While Python has many attractive features, current implementations (read CPython) are not suited for embedded devices, such as microcontrollers and small systems-on-a-chip. This is because CPython uses an awful lot of RAM -- both stack and heap -- even for simple things such as integer addition. Micro Python is a new implementation of the Python 3 language, which aims to be properly compatible with CPython, while sporting a very minimal RAM footprint, a compact compiler, and a fast and efficient runtime. These goals have been met by employing many tricks with pointers and bit stuffing, and placing as much as possible in read-only memory. Micro Python has the following features: - Supports almost full Python 3 syntax, including yield (compiles 99.99% of the Python 3 standard library). - Most scripts use significantly less RAM in Micro Python, and various benchmark programs run faster, compared with CPython. - A minimal ARM build fits in 80k of program space, and with all features enabled it fits in around 200k on Linux. - Micro Python needs only 2k RAM for a basic REPL. - It has 2 modes of AOT (ahead of time) compilation to native machine code, doubling execution speed. - There is an inline assembler for use in time-critical microcontroller applications. - It is written in C99 ANSI C and compiles cleanly under Unix (POSIX), Mac OS X, Windows and certain ARM based microcontrollers. - It supports a growing subset of Python 3 types and operations. - Part of the Python 3 standard library has already been ported to Micro Python, and work is ongoing to port as much as feasible.
