1. Energy PRofiler and Optimizer for Multi-Processor- Design of a system development tool, ePRO-MP
- Profiles both performance and energy consumption of multi-threaded applications
- Presents the analysis results in the program, thread, and function levels
- Performance profiling using performance monitoring counters
- Energy profiling using an energy model without requiring a power measurement equipment
- Performance data and a regression-based energy model
- A limited support for automatic optimization functions based on the profiling results2. Power model for ARM11 MPCore
- A~F : Coefficient
- Instr : the number of instructions
- DL1Access : the number of L1 data accesses
- L2 access : the number of L2 cache accesses
- DataDep : the number of stall cycles
- cohTrans : the number of coherence transactions
- time : program execution time
3. Automatic optimizer for a producer-consumer application
- Analyze the synchronization time between the producer and consumer threads
- Find the near-optimal number of threads for each producer and consumer
