Design Trade-offs

Functionality: Full SPI controller with APB interface
Performance: Configurable SPI clock rates
Flexibility: Multi-slave support and FIFO buffering
Power: Optimized for low-power operation

Technology Considerations

Standard Cell Mapping

SPI Controller maps to standard cell library: - Combinational gates (AND, OR, XOR, MUX) - Sequential elements (DFF, DFFE) - Compatible with most CMOS processes

Power Considerations

Static Power: Minimal (mostly combinational logic)
Dynamic Power: Proportional to SPI clock frequency
Clock Power: APB clock + SPI clock domains
I/O Power: SPI interface switching activity
