The FLAGS register is the status register that contains the current state of an x86 CPU. The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time. Some of those restrictions may include ...
The Portal was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz. [1] [11]It was equipped with 64 kB of main RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (in separate blocks), a LED 32-character one-line screen, a floppy disk (capacity - 140 000 characters), a thermal printer (speed - 28 characters/second), an asynchronous channel, a synchronous channel, and a 220-volt ...
The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.
Program status word. The program status word[a] (PSW) is a register that performs the function of a status register and program counter, and sometimes more. The term is also applied to a copy of the PSW in storage. This article only discusses the PSW in the IBM System/360 [1] and its successors, [2][3][4][5][6] and follows the IBM convention of ...

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of three separate but related issues: data alignment, data structure padding, and packing. The CPU in modern computer hardware performs reads and writes to memory most efficiently when the data is naturally aligned, which generally means that the ...
The DEI council features members from 18 UNC system universities, including NC State University, UNC Charlotte, NC A&T State University, and North Carolina Central University.
A half-carry flag (also known as an auxiliary flag) is a condition flag bit in the status register of many CPU families, such as the Intel 8080, Zilog Z80, the x86, [1] and the Atmel AVR series, among others. It indicates when a carry or borrow has been generated out of the least significant four bits of the accumulator register following the ...
