3.2
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.
Figure 4
Based on these hardware provisions, most of the XC164GM’s instructions can be
executed in just one machine cycle which requires 25 ns at 40 MHz CPU clock. For
