CPU32+
aligned on their natural boundaries. All instruction words and extension words must reside
on word boundaries. Attempting to prefetch an instruction word at an odd address causes
an address error exception.
The CPU32+ has four bits (SZ1, SZ0 and SZC1, SCZ0) in the software status word (SSW)
that are new or have changed definitions.
The CPU32+ offers low power consumption. The CPU32+ is implemented in high-speed
complementary metal-oxide semiconductor (HCMOS) technology, providing low power use
during normal operation. During periods of inactivity, the low-power stop (LPSTOP) instruc-
tion can be executed, shutting down the CPU32+ and other IMB modules, greatly reducing
power consumption.
Ease of programming is an important consideration when using an integrated processor.
The CPU32+ instruction format reflects a predominant register-memory interaction philoso-
phy. All data resources are available to operations that require them. The programming
model includes eight multifunction data registers and seven general-purpose addressing
registers. The data registers support 8-bit (byte), 16-bit (word), and 32-bit (long-word) oper-
and lengths for all operations. Address manipulation is supported by word and long-word
operations. Although the program counter (PC) and stack pointers (SP) are special-purpose
registers, they are also available for most data addressing activities. Ease of program check-
ing and diagnosis is enhanced by trace and trap capabilities at the instruction level.
As processor applications become more complex and programs become larger, high-level
languages (HLLs) become the system designer's choice in programming languages. HLLs
aid in the rapid development of complex algorithms with less error and are readily portable.
The CPU32+ instruction set efficiently support HLLs.
