What do you mean by HDL?

What do you mean by HDL?
I think he may be referring to a tablet computer sold in the UK by Tesco as a Hudl, but I can't be certain, as my crystal ball has clouded over.
hardware description language is (HDL)
Ok, HDL is more for programming FPGAs & ASICs tho.
microController (uC) codee examples are all in assembler & C.
You'd need an HDL compiler for the AVR family.
Google "hdl to c compiler avr", find pages like this one
