How 8085 microprocessor got its name?
the previous CPU of Intel is 8080A. 8085 is the first CPU to work in 5volts. hence the name 8085 (8080+5)
Where can you find information about the Intel 8085 microprocessor architecture?

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.
How many bits are contained in the A register of a 8085 CPU?
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
What are incrementer and decrementer latch in 8085?
In the 8085 microprocessor, incrementer and decrementer latches are used to manipulate the address bus. The incrementer latch increases the address in the program counter (PC) by one, allowing the CPU to fetch the next instruction. Conversely, the decrementer latch decreases the address, which can be useful for looping or managing stack operations. These latches facilitate efficient control over program execution flow during instruction fetching.
What are the applications of hardware interrupts in 8085?
The hardware initiates an interrupt when it feels that the situation requires the CPU's action.
Will a motherbord start or die if turned on without cpu plugged?
It probably won't do either; it would fail during the POST.
When is the CPU used?
Every Time The Computer Is Turned On
What do you mean polling of 8085?
Polling in the context of the 8085 microprocessor refers to the method of checking the status of an external device or peripheral by the CPU at regular intervals. Instead of waiting for an interrupt signal from the device, the CPU actively queries the device to determine if it requires attention or has data to send. This method can lead to inefficient CPU usage, as it consumes processor cycles while checking devices that may not need servicing. Polling is often contrasted with interrupt-driven I/O, where the device signals the CPU when it needs to communicate.
What kind of memory address does a CPU generate?
- An MMU (memory management unit) generates physical address. - A CPU (central processing unit) generates a logical address.
How does the CPU communicate with a device?
There is no such thing as a CPU Drive. If you meant "What does a CPU communicate with", then the answer is everything inside your computer.
What is hardware interrupt of 8085 microprocessor with vector interrupt?
In the 8085 microprocessor, a hardware interrupt is a signal from an external device that temporarily halts the CPU's current operations to allow the device to communicate with the processor. A vector interrupt specifically refers to an interrupt that has a predefined memory address (vector) associated with it, which the processor jumps to when servicing the interrupt. For instance, the 8085 has several hardware interrupts, such as INTR, RST 7.5, RST 6.5, and RST 5.5, each with its own unique vector address, allowing for efficient and organized handling of multiple interrupt sources. This mechanism enables real-time processing and responsiveness to external events in embedded systems.
