Differences between 8085 and 8086 microprocessor

Parameter8085 microprocessor8086 microprocessor
DefinitionThe 8085 is an accumulator-based 8-bit microprocessor that can process 8-bit of data at a time.The 8086 is a register-based 16-bit microprocessor that can process 16-bit of data at a time.
TypeIt is accumulator-based.It is register-based.
Memory segmentationThe 8085 microprocessor does not support memory segmentation.The 8086 microprocessor supports memory segmentation, i.e. the memory of the 8086 microprocessor is segmented which means the 20-bit address bus can access 1 MB of memory but it uses only four 64 kB segments from it.
Arithmetic logic unit (ALU) size8085 contains an 8-bit ALU size.8086 contains a 16-bit ALU size.
Processor configurationIt is a single-processor configuration microprocessor.It is a multiprocessor configuration microprocessor.
Modes of operationThe 8085 microprocessor supports only a single mode of operation.The 8086 microprocessor supports two modes of operation viz. minimum mode and maximum mode.
Pipelining architectureThis microprocessor doesnโ€™t support pipelining architecture.The 8086 microprocessor supports pipelining architecture.
Processor configuration8085 is a single-processor configuration microprocessor.8086 is a multiprocessor configuration microprocessor.
Cost8085 is cheaper in comparison with the 8086 microprocessor.8086 is expensive in comparison with the 8085 microprocessor.
