Interfaces

AXI Interface

The AXI interface is described in a separate chapter.

Applicability to configurations:

Configuration	Implementation
CV32A60AX	AXI implemented
CV32A60X	AXI implemented
CV64A6_MMU	AXI implemented

Debug Interface

The team is looking for a contributor for this section. We can likely reuse an E4 DVplan. Remember: the debug module (DTM) is not in the scope, so we focus on the debug interrupt. How to use the interface (HW/SW). We can refer to RISC-V specifications. If the section is too heavy, promote it to a separate chapter.

Applicability to configurations:

Configuration	Implementation
CV32A60AX	Debug interface implemented
CV32A60X	No debug interface
CV64A6_MMU	Debug interface implemented

Interrupt Interface

The team is looking for a contributor for this section. We can likely reuse an E4 DVplan. How to use the interface (HW/SW). We can refer to RISC-V specifications. If the section is too heavy, promote it to a separate chapter.

The interrupt interface is applicable to all configurations.

TRI Interface

The TRI interface is exclusive of the AXI interface.

For more information, refer to OpenPiton documents.

Applicability to configurations:

Configuration	Implementation
CV32A60AX	No TRI interface
CV32A60X	No TRI interface
CV64A6_MMU	No TRI interface
