... This means that during one single clock cycle, one Arithmetic Logic Unit (ALU) operation is executed. Two operands are output from the register file, the operation is executed, and the result is stored back in the register file - in one clock cycle. Figure 3. The AT90S4434/8535 AVR Enhanced RISC Architecture 2K/ Program Memory Instruction ...

... The ALU supports arithmetic and logic functions between registers or between a constant and a register. Single reg- ister operations are also executed in the ALU. Figure 3 shows the AT90S4434/8535 AVR Enhanced RISC micro- controller architecture. In addition to the register operation, the conventional mem- ory addressing modes can be used on the register file as well ...
