16-bit register that holds the memory address of the next instruction. Stack Pointer (SP): 16-bit register used for stack memory management.
Alters the sequential execution of code either unconditionally or conditionally based on flag settings. JMP 2500H (Unconditionally jump to memory address 2500H)
Utilizing logic gates or decoders (such as the 74LS138) to ensure that only one specific memory chip or I/O device is active for a unique address range. Peripheral-Mapped I/O vs. Memory-Mapped I/O: microprocessor 8085 ppt by gaonkar
If yes, you have found the holy grail. Bookmark it, study it, and pass your exam.
A 16-bit register that sequences program execution. It always holds the memory address of the next instruction to be fetched. 16-bit register that holds the memory address of
Contains assembly language examples (e.g., addition of two 8-bit numbers, finding the largest number in an array) with flowcharts and opcode summaries — helpful for lab preparation.
Performs addition, subtraction, incrementing, or decrementing on data registers or memory pointers. JMP 2500H (Unconditionally jump to memory address 2500H)
A nightmare for students, but essential for engineering interviews. The slides should visually represent:
The heart of the presentation. An animated, color-coded block diagram of the 8085 appears, breaking down the Accumulator, the Temporary Register, the Instruction Register, the Stack Pointer (SP), and the Program Counter (PC). A good PPT will use sequential reveals: first the register array, then the ALU, then the timing and control unit. This mirrors Gaonkar’s methodical deconstruction.
B, C, D, E, H, and L (8-bit each). They can be paired (BC, DE, HL) to act as 16-bit registers.
Use animations to show how data moves from memory to the Instruction Decoder.
