This isn’t especially groundbreaking; this is using the fact that logarithmic number representations don’t require much area to implement if you don’t need high-accuracy and are willing to trade latency for throughput (something that FPGA programmers have been taking advantage of since forever), and then going shopping for algorithms that can still run correctly in such an environment.
