Short Desc. : DCR Interrupt Controller
Overview :
A DCR Interrupt Controller is composed of a bus-centric wrapper containing the IntC core and a DCR bus interface. The IntC core is a simple, parameterized interrupt controller that, along with the appropriate bus interface, attaches to either the OPB (On-chip Peripheral Bus) or the DCR (Device Control Register) bus.
Features : - Priority between interrupt requests is determined by vector position. The least significant bit (LSB, in this case bit 0) has the highest priority.
- Modular design provides core interrupt controller functionality instantiated within a bus interface design currently OPB and DCR buses supported).
- DCR v2.0 bus interface.
- Supports address bus width of 10-bits and data bus width of 32-bits for DCR interface.
- Number of interrupt inputs is configurable up to the width of the data bus.
