4 Central Processor Unit
Based on the powerful MC68020, the CPU32 processing module provides enhanced system perfor-
mance and also uses the extensive software base for the Motorola M68000 family.
4.1 Overview
The CPU32 is fully object code compatible with the M68000 Family, which excels at processing calcu-
lation-intensive algorithms and supporting high-level languages. The CPU32 supports all of the
MC68010 and most of the MC68020 enhancements, such as virtual memory support, loop mode oper-
ation, instruction pipeline, and 32-bit mathematical operations. Powerful addressing modes provide
compatibility with existing software programs and increase the efficiency of high-level language compil-
ers. Special instructions, such as table lookup and interpolate and low-power stop, support the specific
requirements of controller applications. Also included is the background debugging mode, an alternate
operating mode that suspends normal operation and allows the CPU to accept debugging commands
from the development system.
Ease of programming is an important consideration in using a microcontroller. The CPU32 instruction
set is optimized for high performance. The eight 32-bit general-purpose data registers readily support
8-bit (byte), 16-bit (word), and 32-bit (long word) operations. Ease of program checking and diagnosis
is further enhanced by trace and trap capabilities at the instruction level.
Use of high-level languages is increasing as controller applications become more complex and control
programs become larger. High-level languages aid rapid development of software, with less error, and
are readily portable. The CPU32 instruction set supports high-level languages.
4.2 Programming Model
The CPU32 has sixteen 32-bit general registers, a 32-bit program counter, one 32-bit supervisor stack
pointer, a 16-bit status register, two alternate function code registers, and a 32-bit vector base register.
The programming model of the CPU32 consists of a user model and supervisor model, corresponding
to the user and supervisor privilege levels. Some instructions available at the supervisor level are not
available at the user level, allowing the supervisor to protect system resources from uncontrolled ac-
cess. Bit S in the status register determines the privilege level.
The user programming model remains unchanged from previous M68000 Family microprocessors. Ap-
plication software written to run at the non-privileged user level migrates without modification to the
CPU32 from any M68000 platform. The move from SR instruction, however, is privileged in the CPU32.
It is not privileged in the M68000.
