Reconfigurable architectures have gained popularity in recent years as they allow the design of energy-efficient accelerators. Fine-grain fabrics (e.g. FPGAs) have traditionally suffered from performance and power inefficiencies due to bit-level reconfigurable abstractions. Both fine-grain and coarse-grain architectures (e.g. CGRAs) traditionally require low level programming and suffer from long...
Acceleration in the form of customized datapaths offer large performance and energy improvements over general purpose processors. Reconfigurable fabrics such as FPGAs are gaining popularity for use in implementing application-specific accelerators, thereby increasing the importance of having good high-level FPGA design tools. However, current tools for targeting FPGAs offer inadequate support for...
Vectorization has been commonly employed in modern processors. In this work we identify the opportunities to explore customized vector instructions and build an automatic compilation flow to efficiently identify those instructions. A composable vector unit (CVU) is proposed to support a large number of customized vector instructions with small area overhead. The results show that our approach achieves...
