Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing processor architectures are used without address remapper, then device complexity is reduced, but operational flexibility and address translation capability deteriorate
Solution Approach 1:
The address remapper acts as an intermediary component between the processor core and memory system, translating addresses dynamically without requiring changes to the core processor architecture. This mediator approach enables operational flexibility through configurable translation regions while maintaining relative simplicity by isolating the complexity to a dedicated address translation layer rather than redesigning the entire processor.
2Ease of operation
If existing processor architectures are used without event recognition, then device complexity is reduced, but debugging capabilities deteriorate
Solution Approach 1:
The event recognition mechanism provides feedback signals that notify when address translation events occur, such as when a particular address range is accessed or translated. This feedback capability enables debugging by allowing external monitoring of address translation behavior without adding complex intrusive instrumentation to the processor core, thus improving ease of operation while controlling device complexity.
3Difficulty of detecting and measuring
If invasive event detection mechanisms are implemented, then event detection capability is improved, but processor performance deteriorates
Solution Approach 1:
The event detection functionality is extracted from the main processor execution path and implemented as separate monitoring capabilities within the address remapper. This allows event detection to occur in parallel without blocking or slowing down the primary instruction execution flow, thereby maintaining processor performance while improving event detection capability for debugging purposes.
Data Source
AI summary
Systems and methods are disclosed for a configurable interconnect address remapper with event detection. For example, an integrated circuit can include a processor core configured to execute instructions. The processor core includes region registers defined by a From Address range and a To Address, a register storing a number of regions defined in the integrated circuit, interrupt enable registers associated with each pair of region registers, and event flags associated with each pair of region registers; an interconnection system handling transactions from the processor core; an interconnect address remapper translating an address associated with a transaction using the one or more pair of region registers; and an interrupt controller receiving an interrupt signal from the interconnect address remapper when the interrupt enable registers are enabled and at least one raised event flags when at least one of the one or more pair of region registers matches the transaction address.
