Application specific integrated circuit solution for multi-input multi-output piecewise-affine functions. International Journal of Circuit Theory and Applications, 44 (1), 4-20. https://doi.org/10.1002/cta.2058.0098-98861097-007Xhttps://hdl.handle.net/11441/167873This paper presents a fully-digital architecture and its ASIC implementation for computing Multi- Input Multi-Output (MIMO) Piecewise-Affine (PWA) functions. The work considers both PWA functions defined over regular hyper-rectangular and simplicial partitions of the input domains and also lattice piecewise-affine representations. The proposed architecture is able to implement PWA functions following different realization strategies, using a common structure with a minimized number of blocks, thus reducing power consumption and hardware resources. Experimental results obtained with an ASIC integrated in a 90-nm CMOS standard technology are provided. The proposed architecture is compared with other digital architectures in the state-of-the-art habitually used to implement model predictive control applications. The proposal is superior in power consumption (saving up to 86%) and economy of hardware resources (saving up to 40% in comparison with a mere replication of the three representations) to other proposals described in literature, being ready to be used in applications where high-performance and minimum unitary cost are required.application/pdf23 p.engPiecewise-affine (PWA) functionsVLSI digital circuitsResource optimizationEmbedded model predictive controllersinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1002/cta.2058
