Character Codes. and studying related concepts in Introduction to 80x86 Assembly Language Much of the material in this book is based on my previous book, Fundamentals of. The Art of Assembly Language. Page i. The Art of Assembly Language. (Brief Contents). Forward Why Would Anyone Learn This Stuff?.
Customer Review: I would say that running DOS in a virtual machine environment is a great way to learn assembler and Linux provides this opportunity. The author comes up with some very creative ways to teach assembly and the concepts behind programming in general. One of the most powerful teaching aids in my opinion are metaphors. If I can take a complex subject and relate it somehow to something familiar to my students they can internalize the concept easier. The author takes the same approach throughout this book.
Introduction to 80x86 Assembly Language and Computer Architecture. Students using this book will acquire an understandingof how the functional components of computers are put together, and how a computerworks at the machine language level. Short-link Link Embed.

The status register consists of a series of single-bit flags which can affect how the works. There are special instructions which allow you to set or clear each of these flags. In addition, many instructions affect the state of the flags, depending on the outcome of the instruction. For example, one of the bits of the status register is called the Zero flag.
Any operation which ends up generating a bit pattern of all 0's automatically sets the Zero flag on. Setting the flags doesn't seem to do much, until you know that there a whole set of conditional branching instructions which changes the sequence of instruction execution if the particular flags pattern they look for is matched.
In assembly language, the only way to make a decision and branch accordingly is via this flag testing mechanism. The CPU inside your computer can manipulate the bit patterns which make up the computer's memory.
Some of the possible manipulations are copying patterns from one place to another, turning on or turning off certain bits, or interpreting the patterns as numbers and performing arithmetic operations on them.
To perform any of these actions, the CPU has to know what part of memory is to be worked on. A specific location in memory is identified by its address. An address is a pointer into memory. Each address points to the beginning of a byte long chunk of memory. The 80x86 CPU, in its inherent mode, has the capability to distinguish 1,, different bytes of memory.
It is quite clumsy to write 20 bits to get a total of 1,, different addresses, and thus a memory address may be written down as a series of Hexadecimal digits.
For example, the address in hexadecimal is equivalent to in binary. The 80x86 isn't very happy handling 20 bits at a time. The biggest chunk that's convenient for it to use is a 16 bit word.
The 80x86 actually generates 20 bit addresses as the combination of two address words, a segment word and an offset word. The combination process involves interpreting the two patterns as hexadecimal numbers and adding them.
The way that two 16 bit patterns can be combined to give one 20 bit pattern is that the two patterns are added, but out of alignment by one hex digit four bits , as in the example below : bit segment address bit offset address bit memory address Because of this mechanism for calculating addresses, they will often be written down in what may be called segment:offset form. The first is data, just raw patterns of bits for the CPU to work on.
The significance of the patterns is determined by what the computer is being used for at any given time.
