Processor/memory co-exploration at multiple abstraction levels
View Patent ↗Processor/memory co-exploration at multiple abstraction levels. An architecture description language (ADL) description of a processor/memory system is accessed. The ADL description models on one of a plurality of abstraction levels. The abstraction levels may include a functional (or bit-accurate) level and a cycle-accurate level. Further, a communication protocol for the processor/memory system is accessed. The communication protocol is formed from primitives, wherein a memory interface formed from the primitives is useable in simulation at the abstraction levels. A processor/memory simulation model is automatically generated from the description and description of the communication protocol. The processor/memory simulation model comprises a processor/memory interface comprising the primitives and based on the communication protocol. The memory interface allows simulation of the processor/memory on the appropriate abstraction level for the simulation. For example, the processor/memory interface may be a functional interface or a cycle-accurate interface.
