2 Register Set

Chapter 1 Overview

The register set includes data registers for arithmetic and general use, address registers for use as pointers,

and the stack pointer. This set greatly contributes to increasing the internal architecture's performance by

reducing code size and boosting parallel use of pipeline stages.

This register set incorporates features enabling the use of C and other high-level languages.

LAR

The Loop Instruction Register (LIR) and Loop Address Register (LAR) are for speeding up the branch to

and execution of the first instruction in a loop. The SETLB (Set Loop Beginning) instruction loads them

with the next four instruction bytes and the address of the fifth, respectively. The Lcc (Loop) instruction then

uses these stored values to jump-start execution of the first instruction in the loop while fetching additional

instruction bytes.
