the major diff between 8085 and 8086 1s 8085 is a 8 bit
processor 16 address lines where 8086 is a 16 bit with 20
address lines.
the instructions are different
pipelining concept is not seen n 8085
8085 is based on Von-Neumann architecture in which the data
and instructions are in the same memory space without any
distinction between them.8085 is CISC (Complex Instruction
Set Computer.
8085 is a 8 bit processor ie 8 bit data bus. Has got 16
Address Lines. Maximum Operating speed is 3MHz. 8085-A
Operates upto a maximum of 5MHz.
8086 is a 16 bit processor. Has got 20 address lines.
Operates upto 5MHz
8085 is Vonneumann architecture in which data and code is
shared in the by the same memory .
8085 is 16 x 8 bit processor where 8086 is 20 x 16 bit
processor .
8085 is a von neumann architecture.
8086 has 4 segment registers which are not peresent in
8085. also it has preftech queue which stores instructions
ahead of time which is not present in 8085. The BIU and
execution unit in 8086 works parallely which improves its
performance.
8085 is 16*8 bit proc. while 8086 20*16 bit proc.
the major difference is the 8085 have 16 bit address bus
whereas 8086 have 32 bit address bus.there is no seperate
instruction set for multiplication and division for 8085.it
is not so in 8086.
Sir, I hav applied for the post of sec. engg in RRB in
telecom-sigal domain. Can u suggest hows the question
pattern. Do I hav 2 follow technical books or general
aptitude books ?
sir i am completed B.E in 2006 i wrote RRb Section Engineer
Exams two times .how to prepare and how is ask previous
question paper some previous question paper send through mail id
