Detailed Explanation of Grouping Technology in Assembly Language

Concept and Function of Grouping Grouping (Group) is a technique in assembly language that combines multiple logical segments into a single physical segment, addressing the issue of frequently switching segment registers in the 8086/8088 architecture. Through grouping, programmers can treat multiple logical segments as one large physical segment for access, thereby simplifying code writing and … Read more
