Register Operands Fetch
This section describes the general access timing concepts for instruction execution and
internal memory access.
The AVR CPU is driven by the System Clock Ø, directly generated from the external
clock crystal for the chip. No internal clock division is used.
Figure 14 shows the parallel instruction fetches and instruction executions enabled by
the Harvard architecture and the fast-access register file concept. This is the basic pipe-
lining concept to obtain up to 1 MIPS per MHz with the corresponding unique results for
functions per cost, functions per clocks, and functions per power-unit.
Figure 14. The Parallel Instruction Fetches and Instruction Executions
Figure shows the internal timing concept for the register file. In a single clock cycle, an
ALU operation using two register operands is executed and the result is stored back to
the destination register.
