3.1
The main core of the CPU consists of a 4-stage instruction pipeline, a 16-bit arithmetic
and logic unit (ALU) and dedicated SFRs. Additional hardware is provided for a separate
multiply and divide unit, a bit-mask generator and a barrel shifter.
Figure 6
To meet the demand for greater performance and flexibility, a number of areas has been
optimized in the processor core. Functional blocks in the CPU core are controlled by
signals from the instruction decode logic. These are summarized below, and described
in detail in the following sections:
1. High Instruction Bandwidth / Fast Execution
2. High Function 8-bit and 16-bit Arithmetic and Logic Unit
3. Extended bit Processing and Peripheral Control
4. High Performance Branch-, Call-, and Loop Processing
5. Consistent and Optimized Instruction Formats
6. Programmable Multiple Priority Interrupt Structure
