[VHDL-FPGA-Verilog] FPGA例子 Description: FPGA examples, including 8-bit dynamic display, 8-bit priority encoder, 44 matrix keyboard, 8-bit dynamic display, multiplier, multiplexer, BCD code conversion, traffic lights, digital clock, etc., are all engineering files packed, suitable for novices to
9/10/2017 · Gray codes are non-weighted codes, where two successive values differ only on one bit. Through this post, I want to share two simple gate level VHDL codes for converting binary number to Gray and vice versa.
8:3 Binary Priority Encoder : The operation of the priority encoder is if two or more single bit inputs are at logic 1, then the input with the highest priority will be take importance. The coded value will be output. Table shows the truthtable of 8:3 priority. 1) Using if statements :
Verilog / VHDL Projects for $10 - $30. The conventional (single-match) priority encoder finds only one match, i.e. the highest priority input. An n-bit MPZ unit finds r (1 ≤ r ≤ n) matches in exactly r cycles. Design an 8-bitMPZ using HDL...

A selector without priority (generally implemented as a case statement if in a process, or a with-select) may or may not have extra logic over a priority encoder. I think that the last selection in a priority encoder might have a lot of logic indeed. Depends on the design.
