What does the number 8085 mean?

What does the number 8085 mean?

The Intel 8085 (“eighty-eighty-five”) is an 8-bit microprocessor produced by Intel and introduced in March 1976. It is a software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.

Why is it called 8085?

The Intel 8085 microprocessor has got his name as 8085 microprocessor as it is a 8 bit microprocessor and in olden days when they created the first processor of 4 bit named it as 4004 and they don’t that it is a processor which controls whole machine when the invented that its a processor they reversed the last two …

What is the meaning of the instruction in 8085?

Instruction Set of 8085.  An instruction is a binary pattern designed inside a microprocessor to perform a specific function.  The entire group of instructions that a microprocessor supports is called Instruction Set.  8085 has 246 instructions.  Each instruction is represented by an 8-bit binary value.

How many is 8085?

The 8085 (from Intel) is an 8-bit microprocessor. – The 8085 uses a total of 246 bit patterns to form its instruction set. – These 246 patterns represent only 74 instructions.

What is the word length of 8085 microprocessor?

8-bit
A word size of an 8085 microprocessor is 8-bit.

What is the clock speed of 8085?

8085 operates on a clock frequency of 3MHz–6MHz depending upon the version selected. Clock is provided by a crystal oscillator of 2 times the frequency, so as to produce a 50\% duty cycle clock. The minimum operating frequency of 8085 is 500kHz.

What is instruction format in microprocessor?

An instruction is a command to the microprocessor to perform a given task on a specified data. Each instruction has two parts: one is task to be performed, called the operation code (opcode), and the second is the data to be operated on, called the operand.

What is the word length of 8085 microprocessor Mcq?

What is the clock frequency of 8085 microprocessor Mcq?

The clock frequency of an 8085 microprocessor is 5 MHz.

What is clock signal microprocessor?

In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) oscillates between a high and a low state and is used like a metronome to coordinate actions of digital circuits. A clock signal is produced by a clock generator.

What are different instruction format in 8085?

In 8085, the length is measured in terms of “byte” rather then “word” because 8085 microprocessor has 8-bit data bus. Three types of instruction are: 1-byte instruction, 2-byte instruction, and 3-byte instruction. In 1-byte instruction, the opcode and the operand of an instruction are represented in one byte.

What do you mean by instruction format?

An instruction format defines layout of bits of an instruction, in terms of its constituent parts. An instruction format must include an opcode and implicitly or explicitly, zero or more operands. Each explicit operand is referenced using one of addressing modes.

What are the instruction sets of microprocessor 8085?

Microprocessor – 8085 Instruction Sets S.No. Instruction & Description 1 Control Instructions Following is the ta 2 Logical Instructions Following is the ta 3 Branching Instructions Following is the 4 Arithmetic Instructions Following is the

Is 8085 8-bit or 16-bit?

In spite of the fact that 8085 is an 8-bit microprocessor, but there are some instructions are there available in the 8085 instruction set which can do 16-bit additions also. As the 8085 internal architecture is only 8-bits, this instruction easily takes double the time needed to add two 8-bit numbers.

Where is the AC flag in 8085 microprocessor?

But 8085 microprocessor still stores this AC information in bit position 4 of the flags register. The result of execution of DAA instruction, is affected by the status of this flag. However, in our 8085 instruction set does not provide any instruction, which explicitly uses the AC flag.

What is the configuration of 808085?

8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It has the following configuration −. 8-bit data bus; 16-bit address bus, which can address upto 64KB; A 16-bit program counter; A 16-bit stack pointer; Six 8-bit registers arranged in pairs: BC, DE, HL
