Microprocessor 8085 Ppt By Gaonkar -

The instructions are the "language" of the processor. Gaonkar classifies them into functional categories. Data Transfer Instructions

The ALU performs all numerical and logical operations. These include addition, subtraction, AND, OR, and XOR. It uses data from the Accumulator and temporary registers to generate results.

The architecture is divided into several functional units that work in sync to execute instructions. The Arithmetic Logic Unit (ALU) microprocessor 8085 ppt by gaonkar

Program Counter (PC): A 16-bit register that points to the next instruction address.

The power of the 8085 lies in its ability to interact with the outside world. Memory Interfacing The instructions are the "language" of the processor

ALE (Address Latch Enable): Used to demultiplex the AD0–AD7 bus.

The 8085 features five hardware interrupts, ranked by priority: TRAP (Highest priority, non-maskable) INTR (Lowest priority) Instruction Set and Addressing Modes These include addition, subtraction, AND, OR, and XOR

AD0–AD7: Multiplexed address/data lines. This saves pins by using the same lines for the lower 8 bits of the address and the 8-bit data. A8–A15: Higher-order address lines. Control and Status Signals

Should I generate for a lab report?

The 8085 is housed in a 40-pin DIP package. Understanding these pins is crucial for interfacing. Address and Data Bus
