3.3
The main core of the CPU consists of a 5-stage execution pipeline with a 2-stage
instruction-fetch pipeline, a 16-bit arithmetic and logic unit (ALU), a 32-bit/40-bit multiply
and accumulate unit (MAC), a register-file providing three register banks, and dedicated
SFRs. The ALU features a multiply and divide unit, a bit-mask generator, and a barrel
shifter.

Based on these hardware provisions, most of the XC161’s instructions can be executed
in just one machine cycle which requires 25 ns at 40 MHz CPU clock. For example, shift
