Re: [Embedlets-dev] Re: HDL

[Holger B. <ho...@bi...>]

Differences between Hardware and Software are simply not existent. Show 
me the if they exist.

Mostly the hardware today _is_ in fact Software. Not only the 
micrcodes, but in the process of development and construction. I am not 
able to construct any thing more complicated than a binkenlight without 
Software in it.

Software/Hardware is a marketing topic, no more no less.

One is able to move _any_ functionality from HW into SW and vice versa.

PS: Have a look at Finite State Machines, regarding the parallel thread 
- already solved in FSM - Software _and_ Hardware. ... and fundamental 
part of VHDL :)
