Matt,

In our effort to distill the gemac core and related logic, we have 
pulled out the following module under u2_core
SERDES, Dsp core, UART, external RAM interface and the buffer pool

> The mac is all contained in simple_gemac, and above that in

(a) Is any buffering for the gemac done using buffers in the buffer pool 
 or is it ok to eliminate that module all together ?

(b) The synthesis report currently shows that 24 BRAM's are being used 
by the design. Does this sound about right ? Are there modules unrelated 
to gemac or aeMB that we can pull out, to reduce BRAM usage ?

Thanks and Regards,
Vikram.
