Understanding 8085 8086 Microprocessors And Peripheral Ics Link

Unlike the flat memory model of the 8085, the 8086 uses . The 1 MB memory is divided into 64 KB segments. Four segment registers hold the base addresses:

Introduced in 1978, the Intel 8086 was a paradigm shift. It was a with a 16-bit data bus and a 20-bit address bus, allowing it to access 1 MB of memory (220 = 1,048,576 bytes). More importantly, its instruction set architecture (ISA) is the direct ancestor of today’s x86 processors. Every time you run an app on a modern PC, the processor is still executing a variant of the 8086’s original instruction set in real mode. Understanding 8085 8086 Microprocessors And Peripheral Ics
