Intel 8086 and 8088

The Intel 8086/8088 family of microprocessors is a 16 bit architecture on a 16 bit (8086) or an 8 bit (8088) bus. The 8088 was the processor in the original IBM PC, and has evolved into the most popular processor used today in PC's and servers.

Which data structure best support using indirect addressing mode?

The data structure that best supports indirect addressing mode is the linked list. In a linked list, each element (or node) contains a reference (or pointer) to the next element, allowing for dynamic memory allocation and easy traversal. This structure is particularly effective for indirect addressing because it enables the ability to access elements without needing to know their physical memory addresses directly. Additionally, it allows for efficient insertions and deletions, which are beneficial in scenarios where the data size can change frequently.

Which addressing modes does an Intel 386 processor support?

* Direct * Register Indirect * Based Mode * Indexed Mode * Scaled Indexed Mode * Based Indexed mode * Based scaled indexed mode * Based Indexed mode with displacement * Based scaled indexed mode with displacement

How many data buses does a CPU have?

it has 8 data buses and 16 adress buses....that is why it an 8 bit microprocessor

Where is the location for address memory map in the Z80 simulator?

It depends on the particular simulator. You need to be more specific in your question.

Based on what criteria a processor is said to be some x-bit processor?

Generally, the bit size of a processor is indicated by the size of the accumulator, which is, most times but not always, the same as the internal data bus size. The 8086/8088 processor, for instance, is a 16 bit processor. The 8085 is an 8 bit processor. The 80386 is a 32 bit processor. The Q6600 Core2 Quad is a 64 bit processor. (These are just examples.)

What are the advantages of using logical address?

One might be able to get more appropriate traffic to their website or email address if the words that make it up describe it in some way, or are logical.

Why segment is 64k in microprocessor?

Because the processor is a 16 bit processor, and 64k is what you can address with a 16 bit processor.

Why memory to memory acess is not possible in 8086 micro processor?

Memory to memory access is certainly possible in the 8086/8088 microprocessor. Look at the repeated string copy instructions.
