ARM CortexTM-M1

Figure 1 shows an ARM Cortex-M1 processor with debug block diagram.
The NVIC is closely coupled to the ARM Cortex-M1 core
to achieve low-latency interrupt processing. The versions
currently available for use in M1 devices support 1
interrupt with 4 levels of priority. Future versions will
support up to 32 interrupts. To simplify software
development, the processor state is automatically saved
on interrupt entry, and restored on interrupt exist, with
no instruction overhead.
The ARM Cortex-M1 Thumb instruction set’s 16-bit
instruction length allows it to approach twice the density
in memory of standard 32-bit ARM code while retaining
most of the ARM performance advantage over a
traditional 16-bit processor using 16-bit registers. This is
possible because Thumb code operates on the 32-bit
register set in the processor. Thumb code is able to
provide up to 65% of the code size of ARM, and 160% of
the performance of an equivalent ARM processor
connected to a 16-bit memory system.
