Experimental verification of 8085


Experiment No-1

Aim

To write an assembly language for adding two 8-bit numbers by using microprocessor kit.

Apparatus required

8085 micro processor kit, ( 0-5V ) DC battery.

Theory

In order to perform addition in 8085, one of the data should be in the accumulator and another data can be in any one of the general purpose register or in the memory. After addition, the sum is stored in .
The sum of two 8-bit data can be either 8-bit ( sum only) or 9-bit ( sum and carry ).
The accumulator can accumulated only the sum and if there is a carry, the 8085 will indicate by setting the carry flag. Here one of the register is used to account for carry.

Practical-Introduction to Microprocessor


Microprocessor

Practical-Introduction to Microprocessor

Aim

To study the microprocessor 8085

Architecture of 8085 Microprocessor

  a.     General purpose register
     The register B,C,D,E,H,L is known as general purpose register. Each register have 8-bit space to store 8-bit data (i.e. each register make by combination of  8-flip-flop circuit , one flip-flop store 1-bit data).
     The combination of 8 bit register is known as register pair, which can hold 16 bit data.
  b.    Accumulator
    
Accumulator is a 8-bit register, which hold one of the data to be processed by ALU and stored the result of the operation.
  c.     Program counter (PC)
     
Program counter is a 16-bit register, which have the address of next instruction.(i.e. in 8085 the execution of program is start from PC.)
  d.    Stack pointer
     Stack pointer is a 16 bit special purpose register which is used to hold line memory address for line next instruction to be executed.
  e.     Arithmetic and Logic unit
     
Arithmetic and Logic unit carries out arithmetic and logical operation by 8 bit address it uses the accumulator content as input the ALU result is stored back into accumulator.
  f.      Temporary register
     It is an 8 bit register associated with ALU hold data, entering an operation, used by the microprocessor and not accessible to programs.
  g.     Flags
     Flag register is a group of fire, individual flip flops line content of line flag register will change after execution of arithmetic and logic operation. The line states flags are.
i) Carry flag (C)
ii) Parity flag (P)
iii) Zero flag (Z)
iv) Auxiliary carry flag (AC)
v) Sign flag (S)
  h.    Timing and control unit
    
Synchronous all microprocessor, operation with the clock and generator and control signal from it necessary to communicate between controller and peripherals.
  i.       Instruction register and decoder
   
Instruction is fetched from line memory and stored in line instruction register decoder the stored information.
j j.       Register array
  
These are used to store 8 bit data during execution of some instruction. If we want to store 16-bit data then we use pair of register i.e. B-C, D-E, H-L.

Pin Description

Address Bus
1. The pins Ao – A15 denote the address bus.
2. They are used for most significant bit

Address / Data Bus
1. AD0 – AD7 constitutes the address / Data bus
2. These pins are used for least significant bit

ALE : (Address Latch Enable)
1. The signal goes high during the first clock cycle and enables the lower order address bits.

IO / M
1. This distinguishes whether the address is for memory or input.
2. When this pins go high, the address is for an I/O device.

S0 – S1
S0 and S1 are status signal which provides different status and functions.
RD
1. This is an active low signal
2. This signal is used to control READ operation of the microprocessor.

WR
1. WR is also an active low signal
2. Controls the write operation of the microprocessor.

HOLD
1. This indicates if any other device is requesting the use of address and data bus.

HLDA
1. HLDA is the acknowledgement signal for HOLD
2. It indicates whether the hold signal is received or not.

INTR
1. INTE is an interrupt request signal
2. IT can be enabled or disabled by using software

INTA
1. Whenever the microprocessor receives interrupt signal
2. It has to be acknowledged.

RST 5.5, 6.5, 7.5
1. These are nothing but the restart interrupts
2. They insert an internal restart junction automatically.
TRAP
1.  Trap is the only non-maskable interrupt
2.  It cannot be enabled (or) disabled using program
RESET IN
1.  This pin resets the program counter to 0 to 1 and results interrupt enable and HLDA flip flops.
X1, X2
1.  These are the terminals which are connected to external oscillator to produce the necessary and suitable clock operation.
SOD
1.  This pin provides serial input data
SOD
1.     This pin provides serial output data
VCC and VSS
1. VCC is +5V supply pin
2. VSS is ground pin
