Similarly, it is asked, what does STR do in lc3?
This function stores a value (source label) into a destination register. STR stores the value in a source register into a destination register. An immediate offset may also be used.
Additionally, how many bits are used to identify the program counter offset in an lc3 instruction? The LC-3 ISA has 15 instructions, each identified by its unique opcode. The opcode is specified by bits [15:12] of the instruction. Since four bits are used to specify the opcode, 16 distinct opcodes are possible. However, the LC-3 ISA specifies only 15 opcodes.
In this way, what does .fill do in lc3?
fill: tells assembler, put these bits into a word. . string: convert text to . FILL w/ one ascii code per word, NUL terminated.
What is the operation of the ST instruction?
Operation The ST instruction takes the 32-bit integer value contained in the source register specified by the first argument and stores that value in the memory address specified by the second argument (the target address).
