Resource summary
Assembly Language
uses mnemonics to represent the operation codes and addresses.
assembler then translates the assembly language program into machine code for execution
assembler translates assembly language into binary
BRP
branch if positive ->if the answer = a positive number then it'll branch / go to a different part of the code
BRZ
branch if zero -> if the answer = 0 -> jump to a specified line in the code
BRA
will branch whatever the value held in the acc
ADDRSSING MODES
IMMEDIATE
The operand is the actual value
DIRECT
operand holds memory address of the value to be operated on. -> only addressing mode used in the LMC
INDIRECT
operand is the location (typically a register) which holds the address of the data we want. -> enable a larger range of addressable locations.
INDEXED
address of operand is obtained by adding to the contents of an index register -> a constant value.
The number of the index register and the constant value are included in the instruction code,
used to access an array whose elements are in successive memory locations.
OPCODE
OPERAND CODE
specifies the data or memory location of the data on which the operation will be performed
specifies the operation to be performed by the instruction
