Central Processing Unit (CPU)
The main core of the CPU consists of a 4-stage instruction pipeline, a 16-bit arithmetic
and logic unit (ALU) and dedicated SFRs. Additional hardware has been spent for a
separate multiply and divide unit, a bit-mask generator and a barrel shifter.
Based on these hardware provisions, most of the C161K/O’s instructions can be
executed in just one machine cycle which requires 80 ns at 25 MHz CPU clock. For
example, shift and rotate instructions are always processed during one machine cycle
independent of the number of bits to be shifted. All multiple-cycle instructions have been
optimized so that they can be executed very fast as well: branches in 2 cycles, a 16
× 16
bit multiplication in 5 cycles and a 32-/16 bit division in 10 cycles. Another pipeline
optimization, the so-called ‘Jump Cache’, allows reducing the execution time of
repeatedly performed jumps in a loop from 2 cycles to 1 cycle.
