Tasks done previous week • Changes in data formating unit -> ringbuffer -> memory completed and tested – Saves significant resources • Rewrote neighbor module to fix timing problems and change to other clock scheme – Halfway done • Got access to ALTRO code and reviewed changes from ALTRO to S-ALTRO – Resulted in discovering problems of adder rollover which has been implemented – Naming confusions and errors in documentations cleared up • Improved variable pedestal filter (IIR in BC 1) so it will be more useful as a filter – Doubled possible length – Autoreset if it stays outside thresholds for too long – Choice between thresholds being relative or absolute in reference to baseline • • • Zero suppression module-testbench up to 97% coverage Zero suppression added to full chip testbench and verified to work Various bux fixes found during full chip simulations

Tasks in progress • Some recovery cases in the event of errors needs to be handled • Testing functionality implementations – Memory self-test – Test data output ala MPW 1 Register module for collecting errors Implementation of filters in full chip testbench Gatelevel simulations Tail cancelation analysis and verification for better future usability not only for tail cancelation • Finish neighbor rewrite • •
