Question
What is the function of accumulator?
 Question Submitted By :: 86-Family
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
An accumulator is an 8-bit register that is a part of ALU
(Arithmatic-Logic Unit) of a processor.It is used for
temporary storage of 8-bit data and to perform arithmatic
operations like addition,subtraction,multiplication,division
or logical operations like AND,OR,XOR etc.The result of
operation is stored in accumulator.

A hydraulic accumulator is an energy storage device. It is a
pressure storage reservoir in which a non-compressible
hydraulic fluid is held under pressure by an external
source. That external source can be a spring, a raised
weight, or a compressed gas. The main reasons that an
accumulator is used in a hydraulic system are so that the
pump doesn't need to be so large to cope with extremes of
demand, so that the supply circuit can respond more quickly
to any temporary demand and to smooth pulsations.

# 3
The accumulator is an 8-bit register. It can send or
receive data via internal data bus.
It holds one of the quantities to be operated on by the ALU
and receives the result of an operation done by the ALU.
The accumulator is also identified as register A.

accumulator is a device which is prohibited the liquid
particals entering in compressor, it's use for safty of
compressor , because compressor is damage by liguid paticals.
in accumulator have many resister who
prohibited the liquid particals and only vapour refrigerent
pass into the compressor.

The accumulator is an 8 bit ragister associated withthe ALU.
Theragister'A'in the 8085is an accumulator.It is used to
hold one of the operands of an airthmatic and logic
operation.It serves as one input to the ALU.The final
result of airthmatic and logic operation is placed in the
accumulator. There is one typical instruction DADrp,for16
bit addition for which one of the 16-bit operandsis kept in
H-L pairand the other in B-C and D-E pair
