No. > as used in early milkymist soc, I did not remove it for no reason. On-chip SRAM is best used for caches and where high performance is needed, so it is a resource to be used carefully and not wasted to occasionally run small bits of code. A more clever option is to switch the L2 cache to "SRAM mode" (i.e. remove the SDRAM backing like some x86 processors do) but it does not support that atm. So the fastest way of running code from SRAM right now is to use the softusb memory and load it with GDB.
