The following figure shows the configuration tab.
Figure 3-1 Configuration tab
In this tab, you can select the following:
- Number of interrupts
This indicates the number of interrupt sources the Cortex®‑M1 processor supports. There are four fixed values, 1, 8, 16, or 32.
- The IRQ port width remains constant at 32 bits. Unused higher order bits are tied LOW in synthesis. If less than 32 interrupts are configured, you must ensure that any active interrupts are in the active lower order bits.
- OS Extensions
- Enable OS extensions if the Cortex‑M1 processor is defined to include the Nested Vectored Interrupt Controller (NVIC) and Core OS extensions such as SVC and SysTick.
- Small Multiplier
- Enable Small Multiplier if the Cortex‑M1 processor is to use a small but slower multiplier for fabrics that do not have dedicated multiplier resources.
- Big Endian
- Enable Big Endian if the Cortex‑M1 processor is defined to have BE8 big-endian byte ordering.
