Various CPU architecture overview

Hello all,

Is there a website or paper that decribes various CPU architectures
(i.e. 80x86, 8051, MIPS, ARM...)?

I'm looking for pros & cons of various different architectures.

I'm planning on coding up my own CPU in VHDL and I want to do a little
research before I pick and architecture.

Thanks,

Eric

In Phil Koopmans book "Stack Computers, The New Wave" there is coverage of 
the various processor architectures with references. The book is on-line 
somewhere. Try http://www.ece.cmu.edu/~koopman/stack_computers/ for it.

  Shouldn't you focus on the Soft CPU's that are optimised for FPGA 
usage, then ? [ unless you are not bothered by the final speed or 
resource usage.... ? ]

  Things to look at are Opcode size, opcode reach, Opcode decode
and register counts.
  Then there is system resource needs like DataSize, CodeSize and
finally code access itself - something of an achilles heel of
FPGA cpu design.

   Lattice have open sourced their Mico8 offering, so that's a good 
starting point.

Try to get the first edition of Hennessy  / Patterson:

http://www.amazon.com/exec/obidos/tg/detail/-/1558605967/qid=1129059745/sr=8-2/ref=pd_bbs_2/102-7660191-7136155?v=glance&s=books&n=507846

This is a basic reading which covers all aspects about computer
architecture.

Can I recommend this for posting long URLs?
