Central Processing Unit (CPU)
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.

CPU Block Diagram
Based on these hardware provisions, most of the XC164KM’s instructions can be
executed in just one machine cycle which requires 25 ns at 40 MHz CPU clock. For
