When 8085 processor was invented?
The 8085 was introduced by Intel in 1977.
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.
Examples of privileged instructions used by 8085 processor?
There is no protected mode in the 8085 microprocessor, therefore, there are no instructions that are considered privileged.
Why 8085 micro processor is named as 8085?
The 8085 was given its number as the next version of the 8080. The 5 means that it operates on a single 5 volt power source.
What does the 5 in 8085 processor stand for?
5 stands for 5 volt
According to word size how many instruction in 8085?
The 8085 is an 8 bit processor, so its word length is 8 bits.
What is operating frequency of microprocessor?
The operating frequency of 8085 is 3 mhz to 5 mhz
What are the application of 8085 microprocesser?
The Intel 8085 was the successor of the 8080, an early 8 bit processor, used most famously in the Altair. (Microsoft wrote Microsoft BASIC for the 8085 Altair). The boom of home computers took off with the Zilog Z80, a compatible processor but had more features. Today the 8085 isn't used much commercially, the 8051 is a more common 8 bit processor for embedded systems. However the 8085 is extremely popular in engineering schools in the middle east, especially India, as an introductory course to microcomputers.
How many bits in 8085 microprocessor?
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
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.
Why is the data bus in 8085 bidirectional?
So that the processor can both read and write data.
Which register in the 8085 processor is special purpose?
stack register is a special purpose register.
