OS is compulsary to work properly for any processor including 8085 since OS consist of all the instructions that guides the processor,how to react in certain situations........!
The operating frequency of 8085 is 3 mhz to 5 mhz
with neat diagram explain the system bus structure of 8085
The data bus of 8085 is 8 bit.Its operating frequency is 3.03 Mhz.Address bus is 16 bit. The data bus of 8086 is 16 bit.Its operating sfrequency is 5 MHZ.Address bus is 20 bit.
There is no 8085 that operates at 101 MHz. The fastest 8085 operates at 12 MHz, requiring a 24 MHz crystal.
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.
Because that's how Intel designed it. The 8085 is an 8-bit computer operating on a 16-bit address space.
XP is a complete operating system, not simply an operating environment.
There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
The crystal frquency in an 8085 system is twice the desired clock frequency, so a crystal of 2.2 MHz is required to operate at 1.1 MHz.Note: Clock frequency is not the same as instructions per second, because the instructions in an 8085 take a variable number of clock cycles, between 4 and 18, to execute.
The 8085 has a single +5V power supplyThe 8085 has a multiplexed low order address busThe 8085 has extra single pin interrupts, TRAP, RST7.5, RST6.5, and RST5.5The 8085 has serial I/O pins SID and SODThe 8085 has maskable interrupts and the RIM/SIM instructionThe 8085 includes the functionality of the 8224 clock genereator and 8228 system controllerThe 8085 added several 16 bit operations
