Python Configurability
- Resource Configuration - How can we specify what resources are instantiated via the Python config files?
- ResourceType - Type of resource (Enum type)
- ResourceParams - Parameters for this type of resource
- Request - List of requests for this type of resource (Enum type)
- Latency - operation latency and issue latency (intra/inter thread)
- Count - Number of such resource type
- ResourceType - Type of resource (Enum type)
- Pipeline Description
- InstSchedule - Instruction schedule specified as a vector of InstClassSchedule
- InstClassSchedule - Vector of schedules per instruction class - load/store, Int execute, FP execute, specialized inst, etc. (do we still want a distinction between front end and back end schedules?)
- ResourceRequestList - Vector of ResourceRequest (per stage?)
- ResourceRequest - Vector of requests for resources
- ResourceType/Request options
- InstSchedule - Instruction schedule specified as a vector of InstClassSchedule
- Multithreading Models?
- None (single threaded)
- Fine-grained (switch context every cycle or every few cycles, like Ultrasparc T2)
- Coarse-grained (switch context on thread stalls, like 'SwitchOnCacheMiss' currently)
- SMT (all contexts active, like 'SMT' currently)
Simulation Speed
- Instruction Schedule Work
- Use Vector of Vectors instead of Priority Queue
- Identify Instruction Schedule Types (via Tuple)
- Cache Instruction Schedule, Generate On-Demand
- Instructions walk through schedule by incrementing pointer instead of popping from queue
- If dynamic schedule is needed, then copy the remaining part of schedule and let the instruction add/remove as it pleases
- Can we cache dynamic schedules? Is there a better solution here?
- Event-Sleeping Work
- Sleep instructions waiting for an long-delay event
- Sleep CPU w/no activity (partially implemented)
ISA Support
- ALPHA - completed
- MIPS - completed
- X86 - not completed
- SPARC - not completed
Full System Support
- TBD
Checkpointing
- TBD
*Move some of these to Flyspray?*
