A strictly defined load/store architecture minimizes control complexity.
Use of a fixed, 16-bit instruction encoding significantly lowers the
memory bandwidth needed to sustain a high rate of instruction
execution, and careful selection of the instruction set allows the code
density and overall memory efficiency of the CPU architecture to
surpass those of complex instruction set computer (CISC) architectures.
These factors reduce system energy consumption significantly, and the
fully static CPU design uses other techniques to reduce power
consumption even more. The CPU uses dynamic clock management to
automatically power-down internal functions that are not in use on a
clock-by-clock basis. It also incorporates three power-conservation
operating modes, which are invoked via dedicated instructions as
detailed in
