7.8 Instruction Set Overview
Advance Information
172
The M•CORE processor accesses all memory operands through load
and store instructions, transferring data between the general-purpose
registers and memory. Register-plus-four-bit scaled displacement
addressing mode is used for load and store instructions addressing byte,
half-word, and word data.
Load and store multiple instructions allow a subset of the 16
general-purpose registers to be transferred to or from a base address
pointed to by register R0 (the default stack pointer by convention).
Load and store register quadrant instructions use register indirect
addressing to transfer a register quadrant to or from memory.
The instruction set is tailored to support high-level languages and is
optimized for those instructions most commonly executed. A standard
set of arithmetic and logical instructions is provided, as well as
instruction support for bit operations, byte extraction, data movement,
control flow modification, and a small set of conditionally executed
instructions which can be useful in eliminating short conditional
branches.
