Transmuter: Bridging the Efficiency Gap using Memory and Dataflow Reconfiguration

We propose a reconfigurable accelerator for parallel workloads called Transmuter with a software stack called TransPy.

Sparse-TPU: Adapting Systolic Arrays for Sparse Matrices

We develop a hardware-software co-designed solution to accelerate sparse matrix-vector multiplication on a TPU-like systolic array architecture.

A 7.3 M Output Non-Zeros/J Sparse Matrix-Matrix Multiplication Accelerator using Memory Reconfiguration in 40 nm

We prototype a Sparse Matrix-Matrix Multiplication accelerator with 48 heterogeneous cores and a reconfigurable memory hierarchy in 40 nm CMOS that offers significant energy- and bandwidth-efficiency improvements over state-of-the-art CPUs and GPUs.

OuterSPACE: An Outer Product based Sparse Matrix Multiplication Accelerator

We architect a novel hardware-software codesigned accelerator for high-performance, energy efficient sparse matrix multiplication targeting graph analytics and scientific computation.
