BASIC M6502

BASIC-M6502 هو تنفيذ للغة BASIC للمعالجات الدقيقة 8-بت. يوفر بيئة تنفيذ تسمح للبرامج المكتوبة بلغة عالية المستوى تشبه الإنجليزية بالعمل على أجهزة 6502، مع دعم الدوال الرياضية والحساب العشري العائم.

صُمم المشروع لنقل الأجهزة عبر المنصات، باستخدام التجميع الشرطي والماكرو لتكييف كود مصدري واحد عبر أنظمة الحوسبة القديمة المختلفة. ويستخدم طبقات تجريد الأجهزة لإدارة روتينيات الإدخال والإخراج القائمة على الأحرف.

يتضمن النظام إدارة ذاكرة مدمجة مع تخصيص ديناميكي وجمع القمامة (mark-and-sweep) للسلاسل والمتغيرات. كما يوفر بدائيات لمعالجة السلاسل والمصفوفات ويستخدم محاكاة البرمجيات للعمليات العشرية العائمة.

Features

  • 6502 Hardware Programming - Provides a high-level language environment to write and execute programs on 6502 microprocessor hardware.
  • Conditional Compilation Directives - Uses preprocessor directives to include or exclude code blocks based on the target hardware platform configuration.
  • Hardware Porting - Adapts a single codebase to run on various 6502-based computer systems through conditional compilation and macros.
  • Dynamic Memory Allocation - Allocates storage for variables and performs garbage collection on strings to maintain efficient memory utilization.
  • Embedded Memory Management - Handles dynamic memory allocation and garbage collection for strings and variables within low-resource embedded environments.
  • BASIC Language Implementations - Implements a functional BASIC interpreter supporting mathematical functions and floating-point arithmetic on 8-bit systems.
  • Bytecode Interpreters - Implements a bytecode interpreter to reduce memory footprint and increase execution speed on 8-bit hardware.
  • Single Codebase Targets - Maintains a single codebase that can be adapted for different 6502-based computer systems through conditional compilation.
  • BASIC Runtimes - Runs programs written in an English-like BASIC language, including support for floating-point math on 8-bit microprocessors.
  • Floating Point Emulators - Implements complex mathematical operations and decimal arithmetic via software routines for processors lacking native FPU hardware.
  • Retrocomputing - Provides a development environment for building and running legacy-style software on early home computers and 8-bit hardware.
  • Hardware I/O Abstractions - Abstracts character input and output through interchangeable subroutines tailored to specific hardware communication ports.
  • Dynamic Memory Allocation - Implements mechanisms for allocating and reallocating memory dynamically and performing real-time garbage collection in constrained systems.
  • Pure Computation I/O Abstractions - Provides abstraction layers that separate the BASIC interpreter's computation from hardware-specific character I/O routines.
  • Macro-Based Generation - Generates hardware-specific machine code by expanding high-level macros into optimized assembly instructions.
  • Mark-and-Sweep Garbage Collectors - Reclaims memory by identifying unreachable string objects and consolidating fragmented free space using a mark-and-sweep algorithm.
  • Low-Level Machine Code Optimizations - Produces efficient assembly code tailored for specific hardware platforms using a macro system and conditional compilation.

    Carp is a statically typed Lisp compiler that compiles Lisp-like syntax directly to C source code, enabling seamless integration with existing C libraries and low-level system programming. It manages memory deterministically at compile time using ownership tracking and linear types, eliminating garbage collection pauses and runtime overhead while ensuring type safety through an inferred static type system. The language distinguishes itself through compile-time macro expansion and metaprogramming capabilities, allowing code generation and transformation before final binary output. It enforces

    mQuickjs is a compact JavaScript engine designed for memory-constrained devices, such as microcontrollers, requiring as little as 10 KB of RAM and 100 KB of ROM. It achieves this through a fixed-buffer memory allocation scheme that avoids system heap usage, a compacting tracing garbage collector that eliminates fragmentation, and a ROM-embedded standard library that reduces both memory footprint and startup time. The engine compiles JavaScript source into portable bytecode that can be stored in persistent memory and executed without reparsing, and it emulates IEEE 754 floating-point arithmetic

    ArduinoJson is a C++ library for parsing and manipulating JSON data and MessagePack binary streams on microcontrollers with limited memory and processing power. It provides the core primitives necessary for embedded data serialization and parsing, enabling devices to exchange structured data over serial or network interfaces. The library is distinguished by its focus on microcontroller memory management, employing strategies such as pool-based allocation, string deduplication, and non-owning string views to minimize RAM usage. It further optimizes for constrained environments by allowing cons

    MPX is a cross-platform framework designed to build applications for multiple mini-program ecosystems and the web from a single codebase. It utilizes a static transpilation pipeline to transform source code into platform-specific bundles, employing a single-file component system that encapsulates templates, logic, and styles. The framework provides a reactive state management system that automatically synchronizes application data with the user interface through computed properties and watchers. The project distinguishes itself through a robust build-time toolchain that supports sub-package p
