Composable accelerator-rich microprocessor enhanced for adaptivity and longevity

Abstract

Accelerator-rich platforms demonstrate orders of magnitude improvement in performance and energy efficiency over software, yet they lack adaptivity to new algorithms and can see low accelerator utilization. To address these issues we propose CAMEL: Composable Accelerator-rich Microprocessor Enhanced for Longevity. CAMEL features programmable fabric (PF) to extend the use of ASIC composable accelerators in supporting algorithms that are beyond the scope of the baseline platform. Using a combination of hardware extensions and compiler support, we demonstrate on average 11.6X performance improvement and 13.9X energy savings across benchmarks that deviate from the original domain for our baseline platform.
