Re: [lpc2000] Re: Is it possible to port uCLinux in LPC2106

It all depends on your point of reference, if you are comparing against
a Pentium-II or Pentium-3 processor, yes, it would be comparatively "dog
slow".  However, if you are an embedded engineer and have been around
microprocessors for many years, the ARM7TDMI-S @ 60MHz running uClinux
would be sheer joy! <<

Fair enough. I've done some work on a Freescale MCF5272 with uCLinux and 
thought that was painfully slow. As it's a fair bit more powerful than 
an ARM7 I guessed the LPC would be awful.

To be fair, the port for the Coldfire might not have been great and as 
you quite rightly point out, it depends what your expectations are. :) 
 From what I understand, how you compile the Kernel can impact quite 
heavily on the performance.
