On platforms with specialized registers, the A register is usually an accumulator, whose primary function is to store the results (and possibly provide a parameter of) an arithmetic function. In Intel code, for example, add ax,bx adds the contents of ax and bx together, and stores the sum in ax. RISC processors generally do not have specialized registers in this sense, and instead name most their registers generically (e.g. r0, r1, r2...). This allows any general register to perform any general function, including arithmetic. For specific chip dialects, please refer to that chipset's programming manual.

What are the primary fore function performed by microproceser?
A: The processes contains three basic functions, arithmetic's, controller, input/output
What is the advantage of using a CPU register for temporary data storage over using a memory location?
Simple answer - speed. By using the CPU register, the information is kept "local" to the CPU. By storing a value in a memory location, a lookup has to be performed to retrieve it.
Explain Arithmetic micro operation?
The basic arithmetic micro operations are addition, subtraction, increment, decrement, and shift. The arithmetic micro operation defined by the statement:- R3
What is the purpose of using modulo 2 arithmetic rather than binary arithmetic in computing an FCS?
Any arithmetic process would work provided it is applied the same way in the forward and reverse process. Modulo 2 is easy to implement in hardware.
Where can you register a tagline?
Where do I register a tag line in the state of Virginia?
Can arithmetic be performed in the instruction register?
yes
There are four primary operations that are mormally performed on a register?
The four primary operations typically performed on a register are loading, storing, shifting, and manipulating. Loading involves transferring data from memory to the register, while storing sends data from the register back to memory. Shifting refers to moving the bits within the register left or right, often for arithmetic operations or data alignment. Manipulating encompasses various arithmetic and logical operations, such as addition, subtraction, and bitwise operations, on the data contained in the register.
What is the error that occurs when a number becomes too large for the computer to register it?
Arithmetic overflow.
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.
How many types of micro operations performed by CPU?
The CPU typically performs three main types of micro-operations: register transfer operations, arithmetic operations, and logical operations. Register transfer operations involve moving data between registers, while arithmetic operations perform calculations like addition and subtraction. Logical operations deal with bitwise operations, such as AND, OR, and NOT. These micro-operations are fundamental to executing instructions and processing data within the CPU.
Describe the operations performed by the following arithmetic circuits?
The arithmetic circuits on the list that you posted with the question are incapable of performing any operations
Is accumulator a general purpose register?
Yes and no. You can use it as a general purpose register, but if you do that, you will lose the ability to perform arithmetic and logical computations and comparisons that would normally use the accumulator.
Is age quantitative?
Yes, because it has a numerical value and arithmetic can be performed.
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 specify the elementary operations that can be performed on data stored in the registers?
Elementary operations that can be performed on data stored in registers typically include arithmetic operations (such as addition, subtraction, multiplication, and division), logical operations (such as AND, OR, NOT, and XOR), data movement operations (like loading data into a register or storing data from a register), and bit manipulation operations (such as shifting and rotating bits). These operations serve as the fundamental building blocks for more complex computations within a processor.
Difference between a counter and a register?
A register can hold data, and it can be used for temporary storage or, in the case of an accumulator, it can participate in arithmetic or logical operations. A counter is a special case of a register. Usually, it can only be loaded, stored, or incremented, or used for the stack or as the program counter.
What is the function of accumulator 8085?
It is an 8 bit register which is accessable to programmer and is main fuction is to perfom all arithmetic and logical function.
