The M•CORE M210 central processor unit (CPU) architecture is one of
the most compact, full 32-bit core implementations available. The
pipelined reduced instruction set computer (RISC) execution unit uses
16-bit instructions to achieve maximum speed and code efficiency, while
conserving on-chip memory resources. The instruction set is designed
to support high-level language implementation. A non-intrusive resident
debugging system supports product development and in-situ testing.
Total system power consumption is determined by all the system
components, rather than the CPU alone. In particular, memory power
consumption (both on-chip and external) is a dominant factor in total
power consumption of the CPU plus memory subsystem. With this in
mind, the CPU instruction set architecture trades absolute performance
capability for reduced total energy consumption. This is accomplished
while maintaining a high level of performance at a given clock frequency.
