Four kinds of general purporse registers are AX, BX, CX, and DX registersn. AX is the accumulator register that stores the operands performed by ALU. BX is the base register that stores internal addressing,in short it stores memory addresses, CX does the counting, the looping while DX is the data register.
General purpose registers store 8 bits, 16bits and 32 bits data.
Microprocessor consists of different types of registers. They special purpose registers, general purpose registers, address registers, floating point registers and constant registers.
There are two types of registers such as: a) General purpose registers b) Special purpose registers
UNIVAC LARC had 26 general purpose registers, but could be expanded to 99 registers, if required.
The registers in a CPU are organized according to their purpose. There are data registers and address registers. The address registers are in charge of pointing out where certain data stores are.
There exists 4 general purpose registers in 8086 namely Ax(Accumulator),Bx(Base), Cx(Count), Dx(Data).Further these 4 registers are divided into 8 based on higher and lower bits i.e.,. AX- AH &AL, BX-BH & BL, CX- CH & CL, DX- DH& DL. In 8086, there are 4 segment registers: 1. Stack segment 2. Code segment 3. Data segment 4. Extra segment
4
It is one of 4 registers called general purpose registers Ax has a another name witch is (accumulator) it used in arithmetic and logic operation and store data from I/o port in microprocessors like 8086/8088
There are 6 general purpose Registers and Two special purpose registers: General purpose registers(8 bit basically) are B,C,D,E,H,L and SPECIAL Purpose resisters are STACK PONITER,PROGRAM COUNTER these two are 16 bit registers. If u want make general purpose registers as 16 bit registers, the combination is BC,DE,HL these are 16 bit pair registers
Stacks, pointers and registers
General purpose registers are called as scratch pad memories
3 general purposes for writing are: to be informative to be persuasive and to be entertaining
Basically the function of execution unit in 8086 is to perform all arithmetic and logic operations.It tells the Bus Interface unit(BIU) where to fetch instructions and data from.It has 4 components:Control circuitry,ALU,Flag registers and general purpose registers. 1.control circuits-it directs all the internal operations. 2.ALU-performs all logic operations. 3.general purpose registers-used to store data during execution. 4.flag registers-it has a 16bit flag register containing 9 flags that are set for certain conditions during any operation.Ex.carry flag(whenever there is a carry). It also has a decoder to decode the fetched instructions.
