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?
Refer to link below - (cpu-world.com/Arch/8085.html)
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 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
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 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.
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.
What is the address space of 8086 CPU?
The 8086 CPU has a 20-bit address space, allowing it to address a total of 1 MB (2^20 bytes) of memory. This is achieved through a segmented memory model, where memory addresses are specified using a combination of segment and offset values. The segments can start from addresses 0x0000 to 0xFFFF, enabling the CPU to access different memory segments within the overall 1 MB range.
Does data bus and address bus determine the address space of a CPU?
Yes, the data bus and address bus play crucial roles in determining the address space of a CPU. The address bus defines the range of memory addresses that the CPU can access, with its width (number of lines) directly influencing the maximum addressable memory. The data bus, on the other hand, determines how much data can be transferred simultaneously between the CPU and memory. Together, they define the overall capability of the CPU to communicate with memory and peripherals.
