  • Reading and Writing Nibbles in Bytes

    Reading and Writing Nibbles in Bytes

    So, we start again with another project and that is about Reading Nibbles from bytes. So, lets first talk about nibbles arrangement in bytes. As you must be knowing, there are 2 nibbles present in bytes.

  • QBasic Libraries

    First, write a program which contains all the subroutines that you want in your lib. The program can also contain other code but that won’t matter.

  • Interrupts


    Interrupt, as the name suggests, causes an interruption in the program temporarily and causes the processor to execute the statements according to the Interrupt generated. If you didn’t understand it, read on…

  • Cubic Bezier Curves

    Cubic Bezier Curves

    They are also drawn in almost the same method as lines are drawn. Like lines, they require 2 points for start and end of the curve plus 2 more which are known as control points.

  • CPU identification and Analysis using CPUID

    To work with this technology, you have to know Assembly. You need to know about instructions and also binary notation for numbers. You should also know about bits and working with them in Assembly to use this technique.

  • Reading and Writing Bits in Bytes

    Reading and Writing Bits in Bytes

    There are many types of data types. But, here we will be dealing only the sizes of those data types. The basic data type is byte which is 8 bits long, then word or Integer which is 16 bits long, then comes dword(double-word) or Long Integer which is 32 bits long.

  • Processor Data Transfers

    Processor Data Transfers

    The processor and the memory are two important part of the computers that you need to know about when programming. The I/O is also an important part but it is sometimes merged with memory as it can be memory mapped and access to I/O is little different than memory.

  • Hello world and Happy Programmer’s Day!

    Hello world and Happy Programmer’s Day!

    Additionally, I would say that today is also the programmer’s day. I know the programmer’s day is 13th of September of a regular year (and 12th Sep of a leap year) as it is the 256th day of the year.

    I beg to differ (slightly).
