Special purpose registers ( SPR ) hold program state; they usually include the Program_counter(aka instruction pointer), Call_stack, and Status_register(aka processor status word). In embedded microprocessors, they can also correspond to specialized hardware elements
A user visible register (UVR) are the registers visible to programmers. Basically this means that the programmer can only make use of these registers (UVA).These registers includes general purpose or special purpose registers.Example: Data Register, & Address Register.
Special Purpose Machinery
of
In a modern washing machine, the wash, rinse and spin cycles are controlled by special purpose (embedded) computers.
Special purpose memories are areas that offer storage capability for computer data that has a unique purpose. This is an embedded system within the computer that has its own unique language and design tools available to the user.
There are two types of registers such as: a) General purpose registers b) Special purpose registers
Microprocessor consists of different types of registers. They special purpose registers, general purpose registers, address registers, floating point registers and constant registers.
general purpose registers are basically used to hold temporarily data and intermediately result. example: ax,bx,cx,dx each of 16 bits. whereas special purpose register are primely used for memory access. it is of two types : 1. segment register and 2. index register/ pointer
register is small storage space in memory which is in use of processor There are two types of register 1. General purpose register 2. special purpose register

The purpose of providing various registers in a CPU is to enable quick data access and manipulation during processing tasks. Registers serve as small, fast storage locations that hold frequently accessed data, instructions, and addresses, reducing the need to access slower main memory. This increases the overall efficiency and speed of computations, as the CPU can perform operations directly on data stored in registers. Additionally, different types of registers (such as general-purpose, special-purpose, and status registers) facilitate specific functions and enhance the CPU's ability to execute complex instructions efficiently.
A user visible register (UVR) are the registers visible to programmers. Basically this means that the programmer can only make use of these registers (UVA).These registers includes general purpose or special purpose registers.Example: Data Register, & Address Register.
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
UNIVAC LARC had 26 general purpose registers, but could be expanded to 99 registers, if required.
In the Pentium 4 microprocessor, the 32-bit registers are selected based on the architecture's design, which includes a set of general-purpose registers, segment registers, and special-purpose registers. The general-purpose registers (EAX, EBX, ECX, EDX, ESI, EDI, EBP, ESP) can be utilized for various operations, while the segment registers (CS, DS, SS, ES, FS, GS) manage memory segmentation. The selection of registers is also influenced by the instruction set architecture (ISA) and the specific needs of the executing program, allowing for efficient data handling and processing. Additionally, register renaming techniques may be employed to optimize instruction execution and reduce hazards.
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.
i think special purpose computer are like does home appliances, a machine that can perform with one task only
