In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32- bit units. [1] [2] Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle.
Bit manipulation instructions sets ( BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non- SIMD and operate only on general-purpose registers .
The 32-bit variants of Windows 10 will remain available via non-OEM channels, and Microsoft will continue to "[provide] feature and security updates on these devices". This was later followed by Windows 11 dropping support for 32-bit hardware altogether, thus making Windows 10 the final version of Windows to have a 32-bit version available.
Microsoft Macro Assembler. The Microsoft Macro Assembler ( MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows. Beginning with MASM 8.0, there are two versions of the assembler: One for 16-bit & 32-bit assembly sources, and another ( ML64) for 64-bit sources only. MASM is maintained by Microsoft, but since ...
32-bit Disk Access (also known as FastDisk) refers to a special disk access and caching mode available in older, MS-DOS -based Microsoft Windows operating systems. It was a set of protected mode device drivers that worked together to take advantage of advanced disk I/O features in the system BIOS. It filtered interrupt 13h BIOS calls to the ...
In the ARM processor architecture, 26-bit refers to the design used in the original ARM processors where the Program Counter ( PC) and Processor Status Register ( PSR) were combined into one 32-bit register (R15), the status flags filling the high 6 bits and the Program Counter taking up the lower 26 bits. In fact, because the program counter ...
CDC display code. Display code is the six-bit character code used by many computer systems manufactured by Control Data Corporation, notably the CDC 6000 series in 1964, the 7600 in 1967 and the following Cyber series in 1971. The CDC 6000 series and their successors had 60 bit words. As such, typical usage packed 10 characters per word.
Although both technologies are similar, 32-bit disk access (also known as FastDisk) pre-dates Windows for Workgroups 3.11. 32-bit file access provided a 32-bit code path for Windows to directly access the disk bus by intercepting the MS-DOS Int 21H services while remaining in 386 protected mode, rather than handling the Int 21H services in real ...
