Dear Assaff,

We are still continuing with the testing and verification. So far we are synthesizing the soft core on a spartan 3-400 in 
which the block rams are used to implement the 4K ROM. This is done on fly by generating the memory content in VHDL from an HEX file. 
Without optimization the max speed is 112 MHz. Our intention is to have different flavours of the SX 52 Soft core (with ROM of 4K, 8K, 16K, 64K, and why not 256K for Virtex chips ) that can be generated on fly. We have also in mind to extend the soft core for parallel flasm/Ram and serial EEprom interfacing.

Regards,

Aime[/quote]Interesting way to 'extend' the power of the SX Processor. Of course, you won't have access to onboard
comparator, and won't have the oscillator driver for the crystals and resonators, and probably won't have

the ability to directly support 5 volt cmos and ttl logic, but interesting none the less. 

 

Maybe this could be a stepping stone to build a larger more powerful version of the SX. Maybe something that 

supports larger math functions, etc...   ...of course, once the IP core is built, then silicon is only a mask away...
