STRUCTURE REGISTER MEMORY

Register structure

REGISTER
Register is a small computer memory used for data shelters.

Memory is the storage place various forms of information as binary numbers. The information will not be resolved binary form (encoded) by the number of instructions that turns it into a sequence of numbers or figures. For example: The letter F is stored as a decimal number 70 (or binary) using one method of solving. More complex instructions that can be used to store pictures, sound, video, and various kinds of information. The information can be stored in a single sell is called a byte.


The data contained in the register can be processed in a variety of operations with the ability to see how big these registers (8 or 16 bit).
classification Register
General Purpose Register
segment Register
pointer Register
index Register
flag Register
General Purpose Register
Accumulator register AX (16 BIT)
AX = AH (8 BIT) + AL (8 BIT)
BX Base Register (16 BIT)
BX = BH (8 BIT) + N (8 BIT)
CX Counter Register (16 BIT)
CX = CH (8 BIT) + CL (8 BIT)
DX Data Register (16 BIT)
DX = DH (8bit) + DL (8 BIT)
Segment Register?
CS Code Segment Register (16 bits)
DS Data Segment Register (16 bits)
SS Stack Segment Register (16 bits)
ES Extra Segment Register (16 bits)
pointer Register

Instructions IP Pointer Register (16 bits)
Stack Pointer SP (16 bit)
BP Base Pointer (16 bits)
index Register
SI Source Index Register (16 bits)
DI Destination Index Register (16 bits)
flag Register
16-bit register with the following composition:
Architecture Processor 8086/8088
= 1 MB of memory capacity.
There is 1 MB (220) = 1024 8-bit memory cell, the address of 0 s / d 220-1 or 00 000 H s / H d FFFFF
