8086 registers tutorialspoint

What is source index register?
The register SI and DI are called index registers.
These registers are usually used to process arrays or strings.
SI is called source index and DI is destination index.
As the name follows, SI is always pointed to the source array and DI is always pointed to the destination.
What is general purpose register in microprocessor?
General-purpose registers are used to store temporary data within the microprocessor.
There are 8 general-purpose registers in the 8086 microprocessor. 1.
AX: This is the accumulator.
It is of 16 bits and is divided into two 8-bit registers AH and AL to also perform 8-bit instructions.

There are 8 general purpose registers, i.e., AH, AL, BH, BL, CH, CL, DH, and DL. These registers can be used individually to store 8-bit data and can be used in pairs to store 16bit data. The valid register pairs are AH and AL, BH and BL, CH and CL, and DH and DL. It is referred to the AX, BX, CX, and DX respectively.
