CMC − Used to put complement at the state of carry flag CF. A fejlesztése 1976 tavaszán kezdődött, és 1978 nyarán jelent meg. CLC − Used to clear/reset carry flag CF to 0. Derived from the May 2019 version of the Intel® 64 and IA-32 Architectures Software Developer’s Manual.Last updated 2019-05-30.

An instruction set architecture (ISA) is an abstract model of a computer.It is also referred to as architecture or computer architecture.A realization of an ISA, such as a central processing unit (CPU), is called an implementation..

Historically, the first two philosophies to instruction sets were: reduced (RISC) and complex (CISC).

Which was not a result of the baby boom that followed world war ii answers APEX Intel 8086 (亦稱之為iAPX 86) 是由英特爾公司於1976年初開始設計,1978年年中發表的Intel第一款16位元 微處理器。 随後於1979年,又推出了Intel 8088,它在晶片的外部連接椎使用8位資料匯流排(允許使用更廉價和更少積體電路 )的支援,成為8086的一个低成本的簡化产品,并用在IBM PC的原始設計 … The merits and argued performance gains by each philosophy are and have been thoroughly debated. Der Intel 8085 ist ein 1976 eingeführter 8-Bit-Mikroprozessor von Intel.Als Nachfolger des Intel 8080 war er zu diesem binär-kompatibel, integrierte jedoch Taktgenerator und Buscontroller und besaß eine leistungsfähigere Interrupt-Behandlung.Die 5 im Namen bezog sich auf den Fakt, dass der Prozessor nur eine 5-Volt-Betriebsspannung benötigte. The 8086, however, runs on a 16 bit bus, while the 8088 runs on an 8 bit bus. Interrupt Instructions• INT• INTO• IRET 42. An assembly language is almost exactly like the machine code that a computer can understand, except that it uses words in place of numbers. Some of the major drivers of these changes have been... 1. Instruction set of 8086 microprocessor can be divided into data copy/transfer instructions, arithmetic and logical instructions, branch/loop instructions, machine control instructions, flag manipulation instructions, string manipulation instructions. Modern microprocessors can be traced back to their basic version - the 8085, 8086 … [1] x86 integer instructions. The 8086 and 8088 are the same processor, a 16 bit processor, with the same instruction set, registers, and architecture. Microcode is a computer hardware technique that interposes a layer of organisation between the CPU hardware and the programmer-visible instruction set architecture of the computer. Thus it is possible to prefetch even the longest instruction in the instruction set.

This is the full 8086/8088 instruction set of Intel.
