WebbIn this paper we show a real-world example where we created a common network function, RSS, using both traditional RTL/Verilog tools and then using high-level synthesis (HLS) on the same hardware. What we found was surprising: the HLS approach actually used fewer FPGA gates and memory. There is a reason. Read on for details. WebbThe Secure Hash Algorithm (SHA), which functions as a cryptographic hash function, is a key technology in digital authentication. Irreducible polynomials can serve as characteristic functions of the Linear Feedback Shift Register (LFSR) to rapidly generate pseudo-random sequences, which in turn form the foundation of the hash algorithm. honbay furniture reviews
