What is ldi?

LDI, or Load Immediate, is a computer instruction that is commonly used in assembly languages. It is used to load an immediate value into a register.

The syntax for the LDI instruction varies depending on the architecture and instruction set of the processor in use. However, in general, the instruction takes the form:

LDI Rd,imm

The "Rd" is a register destination, and "imm" is an immediate value that will be loaded into the register. The immediate value is typically a small integer or bit pattern that is directly encoded into the instruction.

LDI is a very useful instruction that allows programs to perform operations on constants without the need for memory reads or arithmetic operations. It is also commonly used in control flow instructions, such as branching or looping, where immediate values are used to set flags or counter variables.
