MODULE – 1 MICROPROCESSOR ARCHITECTURE The microprocessor is the central processing unit or cpu of a micro computer.it is the heart of the computer. INTEL 8085: It is an 8 bit Nmos microprocessor.it is an forty pin IC(integrated circuit) package fabricated on a single LSI (Large scale Integration) chip. It uses a single +5 volt d.c.(Direct Current) supply for its operation.It clock spee is 3 mhz.It consists of 3 main sections. 1-Arithmetic Logic Unit(ALU) 2-Timing and control unit 3-Several Registers Arithmetic Logic Unit: It performs various arithmetic an logical operations like aition,substraction,logical an ,xor,or,not,increment etc. Timing and control unit: It generates timing an control signals hich are necessary for the execution of the instructions.it controls the ata flo beteen cpu an peripherals. Several Registers: Registers:-it is a collection of flip flops use to store a binary word.they are used by the microprocessor for the temporary storage and manipulation of data and instructions. 8085 has the following registers: 1-8 bit accumulator i.e. register A 2-6 8 bits general purpose registers i.e. B,C,D,E,H,L 3-one 16 bit regiser i.e.stack pointer 4-16 bit Program counter,Status register,Temporary register,Instruction Register.
