From Claude Shannon developing the notion of Information theory in 1949 to BCH code being independently invented by three scientists in 1959, the era did see some really significant inputs in that era. ref Fun tangent, quick sort […]

## Verilog: Dataflow Modeling

Expressions They combine operators and operands. This is pretty similar to a normal expression in any language. Let’s talk about some interesting one Case Equality/inequality : Equates using x and z Reduction : Reduces it down to one bit by doing interbit operation Concatenation : Literally concatenates the binary numbers Replication : Concatenates and then […]
