The PIC is a very primitive microcontroller, the architecture is not
conducive to multithreading, and only supports a highly restricted
version of C with difficulty. The PIC17C752 only has 16k of program
memory and 678 bytes of RAM.
eCos is designed mainly for 32 bit processors -- take a look at the
list of supported targets. It also needs a GCC port of C and C++.
You will not find many Operating Systems for the PIC, any application
for which a PIC is suitable would not need one.
