How many bits are there in 8085?
Although the 8085 is an 8-bit processor, it has some 16-bit operations. Any of the three 16-bit register pairs (BC, DE, HL or SP) can be loaded with an immediate 16-bit value (using LXI), incremented or decremented (using INX and DCX), or added to HL (using DAD).
How many bytes are there 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.
How many bits are in a microprocessor?
Microprocessor sends out the address of a memory location or I/O location on address bus. In 8085 microprocessor, Address bus is of 16 bits (A0-A15) and can transfer maximum 16 bit address and hence can address 65,536 different memory locations. This bus is multiplexed with 8 bit data bus.
What is 16bit microprocessor?
The 16 bit Microprocessor means that it has 16 address lines. A 16 bit microprocessor is having 16bit register set. It have 16 address and data lines to transfer address and data both. Hence it is 16 address lines. The maximum addresses are 2^16 means 65536.
What is a microprocessor 8085?
Definition: 8085 is an 8-bit microprocessor as it operates on 8 bits at a time and is created with N-MOS technology. The size of the data bus of 8085 is 8 bits while that of the address bus is 16. Therefore, can address 64 KB (i.e., 216) memory.
Is a 16 bit register for 8085 microprocessor Mcq?
The stack pointer in the 8085 microprocessor is a 16-bit register that stores the address of the top of stack memory.
What is bit in microprocessor?
A bit (short for “binary digit”) is the smallest unit of measurement used to quantify computer data. It contains a single binary value of 0 or 1. Additionally, bits are also used to describe processor architecture, such as a 32-bit or 64-bit processor.
Is 8-bit a microprocessor?
In computer architecture, 8-bit integers, memory addresses, or other data units are those that are 8 bits (1 octet or 1 Byte) wide. World’s first 8-bit general-purpose microprocessor 8008 as developed Intel in the year 1972. The Intel 8008 was used in the famous Mark-8 computer kit.
Which is a 16-bit register in 8085 microprocessor?
Stack Pointer
Stack Pointer: The stack pointer in the 8085 microprocessor is a 16-bit register that stores the address of the top of stack memory. The value of the stack pointer is decremented by 2 in PUSH operation. It will increment by 2 in POP operation.
What is the architecture of microprocessor 8085?
Microprocessor – 8085 Architecture 1 8-bit data bus 2 16-bit address bus, which can address upto 64KB 3 A 16-bit program counter 4 A 16-bit stack pointer 5 Six 8-bit registers arranged in pairs: BC, DE, HL 6 Requires +5V supply to operate at 3.2 MHZ single phase clock
Why the program counter in 8085 microprocessor is a 16-bit register?
The program counter in 8085 microprocessor is a 16-bit register, because It counts 16 bits at a time There are 16 address times It facilitates the users storing 16-bit data temporarily
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
What is mnemonic in 8085 microprocessor?
Following is a 16-bit register for 8085 microprocessor 19. The register which holds the information about the nature of results of arithmetic of logic operations is called as 20. When referring to instruction words, a mnemonic is a short abbreviation for the operand address.
