It used to be that you had to work for a big company to be able to
design high-performance processors and systems.
But today, with the average $1000 computer having considerably more
power than the CAD workstations of just a few years ago, we can do
these designs ourselves.
I wonder why we don't see more innovative processor/system solutions
coming from individuals now that the (financial) cost of entry for
making fast, capable systems is almost $0.
We can download free FPGA/CPLD design tools capable of dealing with
large devices, and the devices themselves are pretty cheap.
We can get free PC board design software.
We can get prototype PC boards made for around $33 each.
For instance, using the free ISE Webpack from Xilinx (Altera and
Lattice also have free software like this) you can program a device
like the Virtex XCV300E, which has:
32x48 CLB array
6912 logic cells
411944 system gates
131072 max. block RAM bits
98304 max. distributed RAM bits
and is available in non-BGA forms (i.e. ones that can be
hand-soldered). You can buy them in single quanties for less than
$250.
Take one of these, connect it to some fast DRAM and I/O, and off you
go...
I know Jecel is doing interesting work; why don't we see more
Smalltalk machines coming out of peoples' garages?
