Turbo51
Turbo51 is a compiler for the programming language Pascal, for the Intel MCS-51 (8051) family of microcontrollers. It features Borland Turbo Pascal 7 syntax, support for inline assembly code, source-level debugging, and optimizations, among others. The compiler is written in Object Pascal and produced with Delphi. In the 1980s, Intel introduced the 8051 as the first member of the MCS-51 processor family. Today, hundreds of cheap derivatives are available from tens of manufacturers. This makes the architecture very interesting for professionals and hobbyists. It is surprising that this 8-bit architecture is still in use today, and is still so popular. Of all 8051 compilers, several widely used C compilers exist, but only a few Pascal compilers. Turbo51 is available as freeware and was created with the goal to make a Pascal compiler for MCS-51 processors that will be as fast as Turbo Pascal, will use the same syntax and will generate high quality optimized code.

Object Pascal
Object Pascal is an extension to the programming language Pascal (programming language), Pascal that provides object-oriented programming (OOP) features such as Class (computer programming), classes and Method (computer programming), methods. The language was originally developed by Apple Inc., Apple Computer as ''Clascal'' for the Apple Lisa, Lisa Workshop development system. As Lisa gave way to Mac (computer), Macintosh, Apple collaborated with Niklaus Wirth, the author of Pascal, to develop an officially standardized version of Clascal. This was renamed Object Pascal. Through the mid-1980s, Object Pascal was the main programming language for early versions of the MacApp application framework. The language lost its place as the main development language on the Mac in 1991 with the release of the C++-based MacApp 3.0. Official support ended in 1996. Gen Digital, Symantec also developed a compiler for Object Pascal for their Think Pascal product, which could compile programs muc ...

Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named after French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversions ...

Command Line Interface
A command-line interface (CLI) is a means of interacting with software via commands each formatted as a line of text. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. For a long time, a CLI was the most common interface for software, but today a graphical user interface (GUI) is more common. Nonetheless, many programs such as operating system and software development utilities still provide CLI. A CLI enables automating programs since commands can be stored in a script file that can be used repeatedly. A script allows its contained commands to be executed as group; as a program; as a command. A CLI is made possible by command-line interpreters or command-line processors, which are programs that execute input commands. Alternatives to a CLI include a GUI (including the desktop metaphor such as Windows), text-based menuing (including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comparison Of Pascal And C
The computer programming languages C and Pascal have similar times of origin, influences, and purposes. Both were used to design (and compile) their own compilers early in their lifetimes. The original Pascal definition appeared in 1969 and a first compiler in 1970. The first version of C appeared in 1972. Both are descendants of the ALGOL language series. ALGOL introduced programming language support for structured programming, where programs are constructed of single entry and single exit constructs such as if, while, for and case. Pascal stems directly from ALGOL W, while it shared some new ideas with ALGOL 68. The C language is more indirectly related to ALGOL, originally through B, BCPL, and CPL, and later through ALGOL 68 (for example in case of struct and union) and also Pascal (for example in case of enumerations, const, typedef and Booleans). Some Pascal dialects also incorporated traits from C. The languages documented here are the Pascal designed by Niklaus Wirth, ...

Intel 8051
The Intel MCS-51 (commonly termed 8051) is a single-chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton.. Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary compatible derivatives remain popular today. It is a complex instruction set computer with separate memory spaces for program instructions and data. Intel's original MCS-51 family was developed using N-type metal–oxide–semiconductor ( NMOS) technology, like its predecessor Intel MCS-48, but later versions, identified by a letter C in their name (e.g., 80C51) use complementary metal–oxide–semiconductor ( CMOS) technology and consume less power than their NMOS predecessors. This made them more suitable for battery-powered devices. The family was continued in 1996 with the enhanced 8-bit MCS-151 and the 8/ 16/32-bit MCS-251 family of binary compatible microcontrollers. ...

Relocatable Object Module Format
The Object Module Format (OMF) is an object file format used primarily for software intended to run on Intel 80x86 microprocessors. It was originally developed by Intel around 1975–1977 for ISIS-II, targeting the 8-bit 8080/ 8085 processors. This variant later became known as ''OMF-80''. As ''OMF-86'' it was adapted to the 16-bit 8086 processor in 1978. Version 4.0 of OMF for the 8086 family was released in 1981 under the name Relocatable Object Module Format, and is perhaps best known to DOS users as an ''.OBJ file''. Versions for the 80286 (''OMF-286'') and the 32-bit 80386 processors (''OMF-386'') were introduced in 1981 and 1985, respectively. It has since been standardized by the Tool Interface Standards Committee and was also extended by Microsoft and IBM (''IBM-OMF''). Intel also adapted the format to the 8051 microcontroller (''OMF-51'' and ''AOMF''). File format Many object file formats consist of a set of tables, such as the relocation table, which are either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compiler Optimization
An optimizing compiler is a compiler designed to generate code that is optimized in aspects such as minimizing program execution time, memory usage, storage size, and power consumption. Optimization is generally implemented as a sequence of optimizing transformations, a.k.a. compiler optimizations algorithms that transform code to produce semantically equivalent code optimized for some aspect. Optimization is limited by a number of factors. Theoretical analysis indicates that some optimization problems are NP-complete, or even undecidable. Also, producing perfectly ''optimal'' code is not possible since optimizing for one aspect often degrades performance for another. Optimization is a collection of heuristic methods for improving resource usage in typical programs. Categorization Local vs. global scope Scope describes how much of the input code is considered to apply optimizations. Local scope optimizations use information local to a basic block. Since basic blocks cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freeware
Freeware is software, often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via the same process as ''shareware''. As s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...
