8051 LEARN YOURSELF - TUTORIAL part 2 - SFR DESCRIPTION - 8051 INSTRUCTION SET SUMMARY

            This part briefs briefs about the different SFRs & its description and Instruction Set summary.

 Special Function Registers
          The 8051 operations that do not use the internal 128-byte RAM addresses from 00h to 7Fh are done by a group of specific internal registers, each called a special-function register (SFR), which may be addressed much like internal RAM, using addresses from 80h to FFh. This feature allows the programmer to change only what needs to be altered, leaving the remaining bits in that SFR unchanged. Not all of the addresses from 80h to FFh are used for SFRs, and attempting to use an address that is not defined, or "empty," results in unpredictable results. In Figure 2.1b, the SFR addresses are shown in the upper right corner of each block. 

8051 LEARN YOURSELF - TUTORIAL part 1




            This part briefs gives the introduction of 8051, architecture, Stack and its memory organization. The next part will contain the SFR description and Instruction Set summary.


Microprocessors and Microcontrollers:
          Microprocessors and microcontrollers stem from the same basic idea, are made by the same people, and are sold to the same types of system designers and programmers. What is the difference between the two.

HOW TO CREATE BOOTABLE USB DISK? BOOTABLE PENDRIVE


CREATING BOOTABLE  USB DISK

         To create a bootable USB disk, we need to format the disk into NTFS file system and then add booting files into the partition.

      Open the command prompt and follow the step show in the figure.

Creating USB Boot disk

      Then finally extract the boot image (using winrar or power iso) into the formatted USB disk partition.
       Now your USB boot disk is ready!!!


USES:

          To make os (operating system) formatting Disk , just extract the .iso file in that bootable pendrive, then in system while booting choose usb bootable disk .. now u can use that pendrive as formating CD!!!

               This feature can be used  to avoid the unwanted usage of CDs and DVDs ,and avoids the electronic wastage also !!

MATLAB CODE FOR CIRCULAR CONVOLUTION

MATLAB CODE FOR CIRCULAR CONVOLUTION



The circular convolution, also known as cyclic convolution, of two aperiodic functions occurs when one of them is convolved in the normal way with a periodic summation of the other function.  That situation arises in the context of the Circular convolution theorem.  The identical operation can also be expressed in terms of the periodic summations of both functions, if the infinite integration interval is reduced to just one period.  That situation arises in the context of the discrete-time Fourier transform (DTFT) and is also called periodic convolution.  In particular, the transform (DTFT) of the product of two discrete sequences is the periodic convolution of the transforms of the individual sequences.
