How many total instructions are there in 8085 MP?
there are 74 instruction sets in the 8085 up which consist of 246 bit pattern.
Purpose of program counter in a microprocessor is?
In 8085 program counter stores the address of the next instruction which is to be fecthed.same function is performed by instruction pointer in 8086.
On what voltage do the 8085 and 8086 operate?
The 8085 and 8086/8088 operate on 5 volts.
Explain difference 8085 and 8086 in detail?
a number (1) because 8085+1=8086
Can a program written in 8085 microprocessor run in 8086 microprocessor?
No. They have a different instruction set. However, the processors are sufficiently similar that an 8086 assembler could assemble an 8085 program, given appropriate constants and macros. Some things, however, such as RIM, SIM, RST, etc. do not have equivalents in the 8086.
Can 8085 CPU replace 8086 CPU?
No. The 8086 has instructions not present in the 8085. The 8086 was marketed as "source compatible" with the 8085, meaning that there was a translator program which could convert assembly language code for the 8085 into assembly language code for the 8086. However, this does not mean that the compiled 8086 assembly code would then run on an 8085; among other things, the 8086 was a true 16-bit processor, as opposed to the 8085 which was an 8-bit processor that supported a few 16-bit operations.
What is cache in 8086?
8086 is a small 4 or 6 byte instruction cache or queue that perfetched a few instructions before they were executed. In addition, the 8086 addressed 1M byte of memory, which is 16 times more than 8085. N.K.Jha narayankumarjha2010@gmail.com
What the Difference between accumulator and instruction register?
Examples: /360: no accumulator 8080: A 6800: A and B 8086: AX ...
Why the 16 bit 8085 microprocessor is not possible?
The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
Is rst7.5 is a maskable interrupt in 8086?
No. RST7.5 is a maskable interrupt on the 8085, not the 8086/8088.
Main difference between 8085 and 8086?
The most significant difference between the Intel 8085 and 8086 microprocessors is that the 8085 is an 8-bit system and the 8086 is a 16-bit system. This difference allows the 8086 system to have a much larger set of operational instructions and can make calculations to more significant places. Note: the 8085 processor does have two 16-bit registers. The pointer and the program counter.
What it the size bit address for 8085 and 8086?
128Kb
