Introduction to Microprocessors

Notes analysed in detail (in the spirit of investigating techniques to improve life span). The analyser
is controlled by a user friendly application on a network connected PC. Multiple analysers
can be driven simultaneously be a single PC.
Embedded Device (Flash Analyser) PC/Server (Analyser Interface)
Single board computer (embedded ARM9) Microsoft Windows XP & Vista
Custom daughter board for Flash devices Graphical User Interface
Device driver development Virtual Displays appear on Extended Desktop
Device Driver Adaptation Remote management of devices via TCP/IP
Data acquisition and reporting Memory read/write test case automation
Remote management via TCP/IP Microsoft C, C++, .NET
Questions:
1. Explain the working of Flash Memory Analyzer.

2. Differentiate between embedded device and PC/server analyze interface.

7.5 Summary

• Memory is an essential component in microprocessor system which will allow the user to
store the program and data. Memory consists of thousand of memory cells is capable of storing
1-bit.
• To write into the addressed register, should be asserted low to enable the input buffer, and
then data bits from the data lines are stored into the register.
• The primary function of memory interfacing is to allow the microprocessor to read from and
write into a given register of memory chip.
• The 8085 has a 8 bit input (actually called the input lines of the data bus), meaning that we
8
could have only a maximum of 2 =256 different combination of 1s and 0s as inputs to the
processor.
• A single-board microcontroller differs from a single-board computer in that it lacks the general
purpose user interface and mass storage interfaces that a more general-purpose computer
would have.

7.6 Keywords
• Address decoding: address decoding is used the result in identifying a register with a given
address.
• MPU: The Microprocessor is a programmable logic device; designed with registers, flip flops,
and timing elements.
• OTP: The on-board ROM would be either mask programmed at the chip factory or one-time
programmed (OTP) by the developer as a PROM.
• R/WM: Read/Write Memory is a group of registers to store binary information.

1. Explain the memory structure in the single board microprocessor.
2. Give the circuit analysis of the 8085 microprocessor IC.
