Built SPADE, a SIMD Posit MAC that packs Posit(8,0), (16,1) and (32,2) into one regime-aware, lane-fused datapath so we reuse LODs, complementors, shifters and multipliers instead of replicating hardware; demos on FPGA/TSMC show big area and energy wins and competitive DNN accuracy, so you get multi-precision Posit efficiency without the usual silicon tax.
