6 - CENTRAL PROCESSING UNIT (CPU)
The CPU includes a 4-stage instruction pipeline, a
16-bit arithmetic and logic unit (ALU) and dedi-
cated SFRs. Additional hardware has been added
for a separate multiply and divide unit, a bit-mask
generator and a barrel shifter.
Most of the ST10F269 instructions can be exe-
cuted in one instruction cycle which requires 50ns
at 40MHz CPU clock (PQFP144 devices) and
62.5ns at 32MHz CPU clock (TQFP144 devices).
For example, shift and rotate instructions are pro-
cessed in one instruction cycle independent of the
number of bits to be shifted.
Multiple-cycle instructions have been optimized:
branches are carried out in 2 cycles, 16 x 16-bit
multiplication in 5 cycles and a 32/16-bit division
in 10 cycles.
The jump cache reduces the execution time of
repeatedly performed jumps in a loop, from
2 cycles to 1 cycle.

CP
The CPU uses a bank of 16 word registers to run
the current context. This bank of General Purpose
Registers (GPR) is physically stored within the
on-chip Internal RAM (IRAM) area. A Context
Pointer (CP) register determines the base
address of the active register bank to be accessed
by the CPU.
The number of register banks is only restricted by
the available Internal RAM space. For easy
parameter passing, a register bank may overlap
others.
A system stack of up to 1024 bytes is provided as
a storage for temporary data. The system stack is
allocated in the on-chip RAM area, and it is
accessed by the CPU via the stack pointer (SP)
register.
Two separate SFRs, STKOV and STKUN, are
implicitly compared against the stack pointer
value upon each stack access for the detection of
a stack overflow or underflow.
