Study Notes
Assembler and Assembly Language
- The primary function of an assembler is to translate Assembly language code into machine code.
- A valid Assembly directive is a command that tells the assembler to perform a specific action, such as defining a data segment or reserving space for a variable.
MOV Instruction
- The 'MOV' instruction in Assembly language copies data from one location to another, such as moving a value into a register or memory location.
INT Instruction
- The 'INT' instruction in Assembly Language generates a software interrupt, which allows the operating system to handle specific tasks, such as input/output operations or system calls.
Register Functions
- In x86 Assembly, the EAX register typically serves as an accumulator, holding the results of arithmetic and logical operations.
CMP Instruction
- The purpose of the 'CMP' instruction in Assembly is to compare the values of two operands, setting flags in the flags register based on the result of the comparison.
Loop Instructions
- The 'LOOP' instruction in Assembly is a loop instruction that decrements a counter register and jumps to a specified label if the counter is not zero.
STACK Function
- In Assembly, the 'STACK' segment is a region of memory that stores data and program state temporarily, used to pass arguments to procedures, store local variables, and implement recursive functions.
PUSH Instruction
- The 'PUSH' instruction in Assembly Language pushes a value onto the stack, saving it for later use or passing it as an argument to a procedure.
