6d3bba6cff Tweaks to README.md 
Remove occurrences of ../scripts/ and instead state that it must be in
your PATH.  Also drop the content introducing the isit script as
tracegen+check.sh subsumes this.

ad93e0226d Changes to prepare for switch to TileLink interconnect 
We are planning on switching to a TileLink interconnect throughout and
convert to AXI only on the very edge. Therefore, we need to get rid of
all the existing AXI masters other than the TileLink to AXI converter.

* Get rid of DMA engine for now
* Connect RTC to TileLink interconnect instead of AXI interconnect

5ce3527b88 Merge pull request #32 from ucb-bar/pr-btb-masking 
separate btb response mask from the frontend mask
 2016-03-26 18:15:14 -07:00

f526d380fd separate btb response mask from the frontend mask 
It is now the job of the pipeline to monitor the frontend's valid mask (of
instructions) and the BTB's suggested valid mask (based on the prediction it
makes). Some processors may want to ignore or override the BTB's prediction and
thus can supply their own instruction mask.
