Also referred to as Current PSR (CPSR), to emphasize the distinction between it and
the Saved PSR (SPSR). The SPSR holds the value the PSR had when the current
function was called, and which will be restored when control is returned.
See Program Status Register.
A type of microprocessor that recognizes a lower number of instructions in comparison
with a Complex Instruction Set Computer. The advantages of RISC architectures are:
•
•

The Saved Program Status Register which is associated with the current processor mode
and is undefined if there is no such Saved Program Status Register, as in User mode or
System mode.
See also Program Status Register.
See Should Be One fields.
See Should Be Zero fields.
Should be written as one (or all ones for bit fields) by software. Values other than one
produces unpredictable results.
See also Should Be Zero fields.
Should be written as zero (or all 0s for bit fields) by software. Values other than zero
produce unpredictable results.
See also Should Be One fields.
This instruction enters Supervisor mode to request a particular operating system
function.
See Saved Program Status Register.
A register or variable pointing to the top of a stack. If the stack is full stack the SP points
to the most recently pushed item, else if the stack is empty, the SP points to the first
empty location, where the next item will be pushed.
they can execute their instructions very fast because the instructions are so simple
they require fewer transistors, this makes them cheaper to produce and more
power efficient.
