Written 4.0 years ago by Juilee. 5.2k: Parameter 8086 80386 Pentium; Year of Introduction: 1978: 1985 `1993: Data Bus: 16 bit: 32 bit: 128 bit `Address Bus: 20 bit: 32 bit: 64 bit: Physical memory: 1 MB: 4 GB: 4 GB: Register size: 16 bit. Differences between 8086 and 8088 microprocessors Though the architecture and instruction set of both 8086 and 8088 processors are same, still there are differences between them. Following is the table listing the differences between the 2 microprocessors: This article is attributed to GeeksforGeeks.org. The BIU of 8086 is not as same as in the 8088 but the EU is similar. Features of the 8088: It requires a 1 byte data width which is generated after the de multiplexing of AD0 to AD7 pins. The instruction queue is 4-bytes. Program fetching is performed as soon as there is a byte empty in queue. Comparison between 8086 and 8088. All the changes in 8088 above 8086 are indirectly or directly related to the 8-bit, 8085 compatible data and control bus interface. 1) The predecoded code queue length is reduced to 4 bytes in 8088, whereas the 8086 queue have 6 bytes.
8085 Vs 8086

It has BHE (bar) signal on pin no. 34 & there is no SSO (bar) signal. | It does not have BHE (bar) signal on pin no. 34 & has only SSO (bar) signal. It has no S7 pin. |
| |
It needs one machine cycle to R/W signal if it is at even location otherwise it needs two. | It needs one machine cycle to R/W signal if it is at even location otherwise it needs two. |
In 8086, all address & data Buses are multiplexed. | In 8088, address bus; AD7- AD0buses are multiplexed. |
It needs two IC 74343 for de-multiplexing AD0-AD19. | It needs one IC 74343 for de-multiplexing AD0-AD7. |
Maximum supply current 340mA. | |
