the accumulator is an 8-bit register then is part of the arithmetic/logic unit(ALU). this register is used to store to store 8-bit data and to perform arithmetic & logical operation. the result of an operation is stored in the accumulator. the accumulator is also identified as register A.

What does A represent in 8085 A microprocessor?
'A' means ACCUMULATOR.
What is RAL in a microprocessor 8085?
RAL rotates the content of accumulator Left from Carry
What is lda in microprocessor?
LDA is an Intel 8085 opcode, 3AH, that loads that accumulator from a location specified in memory.
What is STA 3000H in microprocessor?
STA 3000H is an 8085 instruction that says to store the accumulator at memory location 3000H.
In a microprocessor command ADD B means?
ADD B in a microprocessor means to add the contents of the accumulator to the B register and store the result in the accumulator. Flags are set according to the result - Z if zero, C if an unsigned carry occurred, AC if a BCD carry occurred, N if the result is signed negative, O if the parity is odd, OV if a signed overflow occurred. Note that not every microprocessor has every flag listed.
What is 12 bit microprocessor?
The DEC PDP-8 is a 12 bit computer. A 12 bit computer is one where the accumulator and/or bus size is 12 bits.
What is an 12 bit microprocessor?
The DEC PDP-8 is a 12 bit computer. A 12 bit computer is one where the accumulator and/or bus size is 12 bits.
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.
Ora a is executed in intel 8085 microprocessor?
The ORA A instruction does not change the contents of the accumulator. It does, however, set flags to indicate something about the value of the accumulator. In particular, Z means the result is zero, N means it is negative, and P means it has an odd number of ones.
What is the flowchart of 8085 microprocessor for sawtooth on oscilloscope?
(start) load control bit in control register load 00h in accumulator loop:out it to port a increment a repeat loop
How many bits in 8085 microprocessor?
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
How does the microprocessor work?
Suppose we give a 8-bit instruction ADD B to the microprocessor then this instruction is not at all understood by microprocessor as it only accepts binary inputs so first of all it stores the instruction in the INSTRUCTION REGISTOR then it decodes this instruction ADD B to its suitable binary code 80H in the INSTRUCTION DECODER.. after converting to 80H then the microprocessor understands that .. yes i have to add the content of the resistor B with that of A(accumulator) and store the result in the accumulator A this is a small example how microprocessor operates facing the instructions
