I finally read enough articles about high level synthesis (HLS) that give a sense of hype that just didn’t seem to be matched by what I’ve heard. Now hype is pretty subjective, but numbers are not. For example, the High Level Synthesis group on LinkedIn only has 66 members (including myself!); compare that to the FPGA – Field Programmable Gate Array group which has 22,931 members (also including myself). If we were to suppose that HLS tools target FPGA users – which most tools (such as Vivado HLS, NEC CyberWorkbench, ImpulseC, etc.) do, and assuming that both FPGA users and HLS users have a LinkedIn account, then we might conclude from these numbers that less than 0.3% of FPGA users are interested in HLS.
