It includes the ALU, register arrays and control circuits on a single chip. The microprocessor has a set of instructions, designed internally, to manipulate data and communicate with peripherals. This process of data manipulation and communication is determined by the logic design of the microprocessor called the architecture.
The 74LS is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. OE controls the outputs so that the buses are effectively isolated.
All inputs have a Schmitt-trigger action. These octal bus transceivers are designed for asynchronous two-way communication between data buses. Pin diagram of 74LS Logic diagram Positive Logic Memory Devices And Interfacing The memory interfacing circuit is used to access memory quit frequently to read instruction codes and data stored in the memory.
Semiconductor memories are of two types. Where N is number of register and M is the word length, in number of bits. The internal decoder is used to decoder the address lines. It has 12 address lines Ao — A11, one chip select CSone read control signal.
Microprocessor can access 1 Mbytes memory since address bus is bit. But it is not always necessary to use full 1 Mbytes address space. The total memory space depends upon the application.
The individual capacities of program memory and data memory depends on the application. To provide facility to set addresses in the interrupt vector table we must provide RAM at page 0 of memory.
However, it is advised to do that. While interfacing memory to we have to provide odd and even banks of memory.
