What is a literal pool and why do we have them ?

Latest Updated:03/18/2009

Question:

What is a literal pool and why do we have them ?

Answer:

SH instructions are 16 bits in length which means 8-bit immediate data can be encoded directly in the instruction but instead must be stored in memory tables otherwise known as literal pools. The literal pool data is accessed by an immediate data transfer instruction (MOV) using the PC relative addressing mode with displacement.
