What is the difference between 8085 microprocessor and 8086 microprocessor?
The 8086 is enhanced version of 8085 microprocessor. It is 16-bit processor….Differences between 8085 and 8086 microprocessor.
| Property | 8085 Microprocessor | 8086 Microprocessor |
|---|---|---|
| Data Bus Size | 8-Bit | 16-Bit |
| Address Bus Size | 16-bit | 20-bit |
| Clock Speed | 3MHz | Varies in range 5.8 – 10 MHz |
What are the improvements in the architecture of 8086 over 8085 architecture?
Instruction − 8085 doesn’t have an instruction queue, whereas 8086 has an instruction queue. Pipelining − 8085 doesn’t support a pipelined architecture while 8086 supports a pipelined architecture. I/O − 8085 can address 2^8 = 256 I/O’s, whereas 8086 can access 2^16 = 65,536 I/O’s.
What are the features of 8086 microprocessors?
SALIENT FEATURES OF 8086 MICROPROCESSOR

- It is 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing.
What is the advantage of microprocessor?
The microprocessor is very versatile. The microprocessor is its speed, which is measured in basically Hertz. For instance, a microprocessor with a measured speed 3 GHz, shortly GHz is capable of performing 3 billion tasks per second. The microprocessor is that it can quickly move data between the various memory …
What is the disadvantages of microprocessor?
The microprocessor has a limitation on the size of data. Most of the microprocessor does not support floating point operations. The main disadvantage is it’s over heating physically. The microprocessor is does not have any internal peripheral like ROM, RAM and other I/O devices.
What are the three main functions of a microprocessor?
The three functions of a microprocessor are controlling the operations of a computer’s central processing unit, transferring data from one location to another and doing mathematical calculations using logarithms.
What is the major function of microprocessor?
The microprocessor is the central unit of a computer system that performs arithmetic and logic operations, which generally include adding, subtracting, transferring numbers from one area to another, and comparing two numbers. It’s often known simply as a processor, a central processing unit, or as a logic chip.
What is the main function of a RAM?
Computer random access memory (RAM) is one of the most important components in determining your system’s performance. RAM gives applications a place to store and access data on a short-term basis. It stores the information your computer is actively using so that it can be accessed quickly.
What is the function of processor?
A processor (CPU) is the logic circuitry that responds to and processes the basic instructions that drive a computer. The CPU is seen as the main and most crucial integrated circuitry (IC) chip in a computer, as it is responsible for interpreting most of computers commands.
What is difference between RAM & ROM?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
