8085 Microprocessor

What is a Microprocessor? A Microprocessor is a multi-purpose programmable Digital VLSI chip that read instruction from memory and processes data as specified in the instruction. So, • It can understand a fixed set of basic commands known as instruction set. • It has a limited set of on-chip memory locations, known as registers, to hold information (Data to be processed and intermediate results). • The set of instruction (program) and data sets are stored in external memory. • It can generate signals to synchronize & control external devices. Basic Functional Block of Micro-processor The basic functional block diagram, of a microprocessor is shown in the figure. It consists of following Blocks 1. Arithmetic Logic Unit (ALU): This Block performs the arithmetic and logical operations on binary data. It also stores the status of result as binary bits. These bits are known as flag bits. (The width of binary data the ALU can process varies from processor to processor) 2. Register Array: It consists of a few Register to holds the results and the data to

be processed. (The width of register generally depends upon the width of data the ALU can process.) 3. Control Unit: It generates the control signal to synchronize and control the internal operations and to control external devices connected to it. The chip has several pins to send or receive information over it. Sometimes we refer to the connections between the pins, or the pins themselves as lines. Each pin transmits or receives a Boolean signal which is either at logical 0 or at logical 1. Some pins may be in neither of these two states but remain in high impedance state at certain points in time. Such pins, or lines, are said to be tri-state output pins or lines. N-bit Processor: A processor in which most of the instructions process N-bit wide data at a time is said to be N-bit. So, the width of ALU is N-bit. An N-bit processor may have N-bit-wide registers, an N-bit-wide internal bus. In an N-nit processor, most of the instructions operates on N-bit data. • Motorola 68000 is classified as a 16-bit processor. The ALU is 16-bit wide, but the registers in the processor are 32-bit wide. • Common processor sizes are 4-bit, 8-bit, 16-bit, 32-bit, 64 bit.

8085 Features

1. 8085 Microprocessor is an 8-bit Microprocessor.So, it can process 8-bit data simultaneously. 2. 8085 microprocessor requires a single +5V DC power supply. 3. An 8-bit Accumulator and Six 8-bit general purpose register that can also be used as 3 register pair to work as a 16-bit register. 4. With a 16-bit address bus and 8-bit data bus, it can address 64k memory location of 8-bit width. 5. To reduce the no of pins the lower byte of address bus is time multiplexed with 8-bit data bus. So, requires an 8-bit latch to de-multiplex data bus from address bus externally. 6. It supports 256 input and 256 output devices with an 8-bit I/O address placed both in lower and higher byte of address bus. 7. Support asynchronous serial communication. 8. One 16-bit stack pointer to manage the stack. 9. A 16-bit program counter, that points to the location of next instruction to be executed. 10. 5 flags in an 8-bit flag register. 11. Support 5 Hardware interrupts, TRAP, RST 5.5, RST 6.5, RST 7.5, INTR. 12. It contains an on-chip clock generator. external clock generator is not required, but requires a crystal, LC tank or RC circuit to be connected externally. 13. It operates on clock frequency from 500 kHz to 3 MHz with 50% duty cycle. However, 8085A- 2 can operate with a maximum clock frequency of 5MHz. 14. It can perform addition, subtraction, and logical operation (AND, OR, XOR, Complement). It does not support Multiplication and Division. 15. Support BUS sharing for DMA operation. Arithmetic Logic Unit (ALU):

It consists of arithmetic and logical circuits to perform desired operation on the

two operands stored in accumulator and Temporary register. The result is stored in Accumulator. This is governed by control signals generated by control and timing signal. It can perform the following operation.  Binary addition, subtraction, increment and decrement,  Logical AND, OR and EX-OR,  Complement,  Rotate left of right. The ALU contains additional logic for BCD arithmetic. The circuit adjust the addition result to correct BCD. Accumulator: Accumulator (A) is a special function register used to store 1. One of the operands in arithmetic and logical instruction 2. Store the result after arithmetic and logical operation Temp register:  Not accessible to a programmer i.e. it can not be read or write directly or indirectly by any instruction.  Temp register holds the 2nd operand and fed to the ALU during the execution of arithmetic and logical operations

Flag Register/Flip-Flops  5 flags are used to store the status of results after execution of arithmetic and logical operations.  It reflects the data condition after execution of Arithmetic and Logical operation.  The value of a flag is used in taking certain decision. Based on the status of a flag different set of instructions are executed.

S – Sign Flag • S=1, when the result is Negative ( in Accumulator in 1). • S=0. Indicates the result is +ve. • Useful in signed arithmetic to determine the sign of the result. Z – Zero Flag • Z=1, when the result is 0 (all bits in the accumulator are 0) after any arithmetic or logical operations. • Z=0, if all bits in the accumulator after a logical or arithmetic operations are not zero. AC – Auxiliary Carry Flag • AC=1, when a carry generated from bit to bit or a borrow from bit to bit. (i.e. A carry from lower nibble to higher nibble or borrow from higher nibble to lower nibble.)AC=0, if no carry or borrow. • Used by DAA instruction to convert the result to BCD form. P – Parity Flag • P=1, when result in accumulator has even number of 1. • P=0, if the number of bits in the accumulator is odd. CY – Carry Flag • CY=1, when a carry from (MSB) bit during addition or borrow to (MSB) bit in subtraction. • CY=0, otherwise
