A presentation at the Linux Plumbers Conference on September 7, 2011, covered the x32 ABI. [2] The x32 ABI was merged into the Linux kernel for the 3.4 release with support being added to the GNU C Library in version 2.16. [14] In December 2018 there was discussion as to whether to deprecate the x32 ABI, which has not happened as of April 2023 ...
In PMBus, blocks may include up to 255 bytes (vs. the 32-byte limit of SMbus). As in SMBus 2.0, only seven-bit addressing is used. Some commands use the SMBus 2.0 block process calls. Either the SMBALERT# mechanism or the SMBus 2.0 host notify protocol may be used to notify the host about faults.
An eight-bit processor like the Intel 8008 addresses eight bits, but as this is the full width of the accumulator and other registers, this could be considered either byte-addressable or word-addressable. 32-bit x86 processors, which address memory in 8-bit units but have 32-bit general-purpose registers and can operate on 32-bit items with a ...
The SIB byte is an optional post-opcode byte in x86 assembly on the i386 and later, used for complex addressing. If present, it appears immediately after the ModR/M byte, before any displacements. If present, it appears immediately after the ModR/M byte, before any displacements.
On z/Architecture, [3] prefixing operates on 8196-byte blocks. IBM classifies addresses on these systems as: [4] Virtual addresses: addresses subject to dynamic address translation; Real addresses: addresses generated from dynamic address translation, and addresses used by code running in real mode; Absolute addresses: physical addresses
VAX (an acronym for Virtual Address eXtension) is a series of computers featuring a 32-bit instruction set architecture (ISA) and virtual memory that was developed and sold by Digital Equipment Corporation (DEC) in the late 20th century.

A 32-bit register can store 2 32 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 32 − 1) for representation as an binary number, and −2,147,483,648 (−2 31) through 2,147,483,647 (2 31 − 1) for representation as two's complement.
