The search for a specific "new" PPT paper by Ramesh Gaonkar for the 8085 microprocessor does not yield a single standalone research paper. Instead, Gaonkar’s work is primarily encapsulated in his definitive textbook,
: Uses five distinct modes—Immediate, Register, Direct, Indirect, and Implied.
during addition. Used for Binary Coded Decimal (BCD) operations.
Ramesh Gaonkar’s textbook, Microprocessor Architecture, Programming, and Applications with the 8085 , is the definitive gold standard for students worldwide. Core Features of the 8085 Microprocessor microprocessor 8085 ppt by gaonkar new
: Connected to a crystal oscillator to set the internal operating frequency.
: Second highest. Maskable, edge-triggered. Vectored to 003CH . RST 6.5 : Maskable, level-triggered. Vectored to 0034H . RST 5.5 : Maskable, level-triggered. Vectored to 002CH .
Timing Analysis—showing step-by-step T-states for an Opcode Fetch and Memory Read. The search for a specific "new" PPT paper
: Defining the programmable VLSI chip that includes an ALU, registers, and control circuits.
Because multiple chips share the system bus, address decoding circuitry (using NAND gates or 3-to-8 decoders like the 74LS138) ensures that only one device is active at any given address range. Key Peripheral ICs Covered by Gaonkar
One complete subdivision/cycle of the master clock signal. Example: Opcode Fetch Machine Cycle (Typically 4 T-States) T1cap T sub 1 Used for Binary Coded Decimal (BCD) operations
The 8085 is an 8-bit general-purpose microprocessor introduced by Intel in 1976. Gaonkar’s approach emphasizes that the 8085 is a programmable device that processes binary numbers according to instructions stored in memory. Slideshare Word Size: Clock Speed: Standard frequency of 3 MHz. Power Supply: Operates on a single +5V supply. 40-pin Dual In-line Package (DIP). Slideshare 2. Architecture and Hardware Details
Executes boolean logic operations like AND, OR, XOR, compare, or bit rotations (e.g., ANA , ORA , XRA , CMP , RLC ).
: Includes an 8-bit Accumulator , six general-purpose 8-bit registers (B, C, D, E, H, L) which can be used in pairs (BC, DE, HL), a 16-bit Program Counter (PC) , and a 16-bit Stack Pointer (SP) .
