Computer Architecture Just like an architect designs buildings, a computer architect designs computers. So computer architecture is the study of – how computers are designed, – why they are designed that way, and – what are the effect of different designs on their performance. It isn't just computer architects who need this knowledge: it is anybody who really needs a computer to do work for them, or needs to write software for that computer.

Computer Architecture Of course, any of us can use a computer or computer related devices but …. efficientlyhigh performance to use them very efficiently, or for high performance computation we need to really understand what is happening inside.

To design your own “computer”: Up to 1900 You needed to be wealthy Also have a lot of space to work in, and time to do it! Working for the military? Employed by large computer company in UK/USA todayIn the electronics industry, using off-the-shelf CPU device todayStart with a single chip micro (PIC, LPC, MSP series, etc.) 1990 futureYou can design your own CPU and implement it on a programmable logic device such as an FPGA For the first time in computing history, individuals can now easily and quickly design new computers, implement and test them with free tools, and inexpensive hardware, and use them in their own designs. The Future of Computing

You may not build the world’s fastest supercomputer but hopefully you will be designing or programming some amazing embedded systems in near future… The Future of Computing
