The reset vector for 6502 processor family is a 16-bit address stored at 0xFFFC and 0xFFFD. The reset vector for 6800 and 6809 processor families is a 16-bit address stored at 0xFFFE and 0xFFFF. No Reset Vector. For 8051 / 8080 / 8085 / Z80, reset starts code execution at address 0x0000.
MinGW ("Minimalist GNU for Windows"), formerly mingw32, is a free and open source software development environment to create Microsoft Windows applications.. MinGW includes a port of the GNU Compiler Collection (GCC), GNU Binutils for Windows (assembler, linker, archive manager), a set of freely distributable Windows specific header files and static import libraries which enable the use of the ...
Watcom C/C++ (currently Open Watcom C/C++) is an integrated development environment (IDE) product from Watcom International Corporation for the C, C++, and Fortran programming languages. Watcom C/C++ was a commercial product until it was discontinued, then released under the Sybase Open Watcom Public License as Open Watcom C/C++.
The cdecl (which stands for C declaration) is a calling convention for the programming language C and is used by many C compilers for the x86 architecture. [1] In cdecl, subroutine arguments are passed on the stack.
Here is a simple example of index register use in assembly language pseudo-code that sums a 100 entry array of 4-byte words: Clear_accumulator Load_index 400,index2 //load 4*array size into index register 2 (index2) loop_start : Add_word_to_accumulator array_start,index2 //Add to AC the word at the address (array_start + index2) Branch_and_decrement_if_index_not_zero loop_start,4,index2 //loop ...
LCC ("Local C Compiler" or "Little C Compiler") is a small, retargetable compiler for the ANSI C programming language. Although its source code is available at no charge for personal use, [2] it is not open-source or free software according to the usual definitions because products derived from LCC may not be sold, although components not derived from LCC may be sold. [1]
The compiler's words use specially named versions of fetch and store that can be redirected to a buffer area in memory. The buffer area simulates or accesses a memory area beginning at a different address than the code buffer. Such compilers define words to access both the target computer's memory, and the host (compiling) computer's memory. [31]
Given the fact there is no standard on which to base the implementation, the functions declared by process.h differ, depending on the compiler in use. Below is a list of compilers which provide process.h. DJGPP [3] [4] OpenWatcom, [5] [6] Digital Mars [7] [8] MinGW [9] Microsoft Visual C++ [10] Borland Turbo C, 2.0 and later [11] [12] Lcc32 [13]
