An accumulator is a register where arithmetic and logic operations are performed and their results stored (accumulated). Usually one operand was already stored in the accumulator while the other came from memory, the immediate value field of an instruction, or if the computer has them another register.
Many early computers had only one accumulator and a small number of index registers. On such machines the accumulator register itself is the ALU, it has all the special circuits inside itself to perform those operations and modify its own contents. The flipflops that store the data in an accumulator are usually JK-flipflops, which simplify the design of those special circuits.
Later when computers began to use multiple general purpose registers the concept of the accumulator fell out of favor. On such machines one separate ALU was shared with all the registers, which were reduced to just a small bank of very high speed RAM with no special circuits like accumulators usually have.

What did George Boole invent?
George Boole invented the digital computer logic also known as Boolean logic.
Where Pathos or logos Declaration of Independence?
Jefferson doesn't use the term but for him it would have meant logic. To think something through and in the Declaration you can see his logic in the first paragraph or two when he explains why government is important, what it should do for the people, and why the people have the right to change government.
What rhetorical devices does Benjamin Franklin use in his essay the whistle?
He used logos. Which is a form of using logic and facts to make a statment. He also used some rhetorical questions but not many. Its when you ask a question that is not meant to be answered.
What is the size of the accumulator register of 64 bit processor?
64 bit. the size of accumulator will always equal to the size of processor. e.g 32 bit processor has 32 bit accumulator.-------------------------------------------------------------------------------------------------------------------------------------------Actually on some computers the accumulator(s) are larger than the processor word size. Some examples are:IBM 704, IBM 709, IBM 7090, IBM 7094 - these are 36 bit processors with a 38 bit accumulatorIBM 7030 - this is a 64 bit processor with a 128 bit accumulatorSome computers do not have accumulator(s), these fall into three main groups:Variable word length machines that store all data in main memoryGeneral purpose register machinesStack machines that either have a fixed sized internal stack or a variable sized stack stored in main memory
What is formal and material logic?
Formal logic concerns itself primarily to the correctnes rather than than the truth of a logical process. Material logic on the other hand is the truth of a material content.
What is accumulator in digital logic?
It is a variable or a component of a variable.
What products use logic gates?
All digital electronic circuits are composed of logic gates. Without logic gates there would be no digital electronics.
Which logic is used by odd parity generators?
Digital Logic
What are the basic digital logic gates?
And,or,not
What is digital electronic?
Digital Electronics deals with logic 1 and logic 0, where logic 1 is represented by one voltage and logic is represented by another voltage.(ie. it is a discrete representaiton of analog signals). The main advantage of digital signals over analog signal is that it is less prone to noise.
What are registers that are designed to store the results of logic operations?
The register that stores the result of (an arithmetic) or logical result is the accumulator.
What is the difference between OR diagram and OR circuit?
OR diagram is a drawing or plan of the digital logic OR function, it is not able to actually do anything only tell a person something about this logic functionOR circuit is the actual electronics implementing the digital logic OR function, it is actually able to carry out this logic function in a digital device or system
What is an accumulator in microprocessor?
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 is a ribbon spool?
it is a signal of digital logic
What is the conclusion of logic gate during seminar?
A logic gate is used to implement any digital logic. It may be AND, OR, XOR, NOT, XNOR, NAND, NOR. These logic gates can be used to implement the output equations of digital circuits in order to design them.
What is meant by universal logic gate?
A logic gate is a digital circuit (made of transitors) that calculates a Boolean truth value. Example operations are AND, OR, NOT.A universal logic gate is one that can be put together in different configurations to perform all the Boolean operations.There are two universal logic gates: NAND (not-AND) and NOR (not-OR).See related link.
What has the author M Morris Mano written?
M. Morris Mano is known for writing several influential textbooks on computer science and digital design, including "Digital Design" and "Computer System Architecture." These books are widely used in engineering courses and have helped many students understand the fundamentals of digital logic and computer architecture.
