A non-programmable 8-bit register used internally by the ALU.

: Contains five flip-flops (Sign, Zero, Auxiliary Carry, Parity, Carry) that reflect the status of the accumulator after an operation. 16-Bit Registers : microprocessor 8085 ppt by gaonkar

Operands are stored inside internal registers (e.g., MOV A, B ). A non-programmable 8-bit register used internally by the ALU

One subdivision of an operation corresponding to one internal clock period. Step-by-Step Execution: The Opcode Fetch Cycle One subdivision of an operation corresponding to one

The time required to complete one access operation to external memory or an I/O device (typically requires 3 to 6 T-states). T-State: One complete subdivision of a clock cycle.

The ALU is the "brain" that performs additions, subtractions, and logical operations (AND, OR, XOR). The results of these operations often affect the Flag Register , which indicates conditions like Zero, Carry, or Sign. EEE226 - School of Electrical and Electronic Engineering

Data is explicitly provided within the instruction (e.g., MVI B, 05H ).
