What is the improvement in 8086 over 8085?

There are some advantages of 8086 over 8085 e.g. more memory, faster clock speeds, backward compatibility, sort of better math etc. some of them are as follows: 8086 is 16 bit microprocessor whereas 8085 is 8 bit microprocessor. 8086 has 20 bit address bus while 8085 has 16 bit address buss.

What is the improvement is in the architecture of 8086 over 8085 architecture?

Memory − 8085 can access up to 64Kb, whereas 8086 can access up to 1 Mb of memory. Instruction − 8085 doesn’t have an instruction queue, whereas 8086 has an instruction queue. Pipelining − 8085 doesn’t support a pipelined architecture while 8086 supports a pipelined architecture.

How do you push the 8086 microprocessor in maximum mode?

Maximum Mode 8086 System In the maximum mode, the 8086 is operated by strapping the MN/MX pin to ground. In this mode, the processor derives the status signal S2, S1, S0. Another chip called bus controller derives the control signal using this status information.

What are the features of 8086 microprocessors?

1) The 8086 is a 16-bit microprocessor. The term “16-bit” means that its arithmetic logic unit, internal registers and most of its instructions are designed to work with 16-bit binary words. 2) The 8086 has a 16-bit data bus, so it can read data from or write data to memory and ports either 16 bits or 8 bits at a time.

What basic features has been added in 8086 microprocessor which were absent in 8085 microprocessor?

Whereas pipelining is supported by the 8086 microprocessor. Instruction queue is absent in 8085 microprocessor. While as queuing is supported by 8086 it has instruction queue. Memory segmentation is not supported by 8085 while it is supported by the 8086 microprocessor.

How does the 8086 microprocessor support segmentation?

Segment Registers: ➢ The 8086 architecture uses the concept of segmented memory. 8086 able to address a memory capacity of 1 megabyte and it is byte organized. This 1-megabyte memory is divided into 16 logical segments. Each segment contains 64 Kbytes of memory.

How many pins are there in 8086 microprocessor?
