The data objects in VHDL and Verilog form expression operands. Knowing the operand differences between the two HDLs helps you write more efficient chip-design code. Expressions consist of operators ...

In this paper, the authors propose a 32 bit linear feedback shift register which generates pseudo-random test patterns as the input bit is a linear function of its previous state.

This new 16-bit CPU is implemented in VHDL for an FPGA. The really cool thing about this CPU is that it eschews the typical program counter (PC) and replaces it with a linear-feedback shift ...
