Cycle-approximate Retargetable Performance Estimation at the Transaction Level
This paper presents a novel cycle-approximate performance estimation technique for automatically generated transaction level models (TLMs) for heterogeneous multicore designs. The inputs are application C processes and their mapping to processing units in the platform. The processing unit model consists of pipelined datapath, memory hierarchy and branch delay model. Using the processing unit model, the basic blocks in the C processes are analyzed and annotated with estimated delays. This is followed by a code generation phase where delay-annotated C code is generated and linked with a SystemC wrapper consisting of inter-process communication channels. The generated TLM is compiled and executed natively on the host machine. Our key contribution is that the estimation technique is close to cycle-accurate, it can be applied to any multi-core platform and it produces high-speed native compiled TLMs. For experiments, timed TLMs for industrial scale designs such as MP3 decoder were automatically generated for 4 heterogeneous multi-processor platforms with up to 5 PEs under 1 minute. Each TLM simulated under 1 second, compared to 3-4 hrs of instruction set simulation (ISS) and 15-18 hrs of RTL simulation. Comparison to on-board measurement showed only 8% error on average in estimated number of cycles.
