+Code Improvements
+David_Harris@hmc.edu 15 Nov 2021
+
+Remove depricated N-Mode stuff, including sd in privileged.sv
+Look at version 13? of privileged spec.  What should we add?
+Reduce size of repo
+
+Timing optimization (Kip, Shreya)
+    Use ForwardSrcA instead of SrcA for mdu / fpu
+    Look at TLB -> PMP -> Access Fault -> Trap
+        may be able to precompute
+    Try flattening, see speedup
+    Take out Mul synthesis modes
+
+RISCV-Arch-tests 
+    Port MMU tests
+
+FPU
+    spec difference on signaling/quiet NAN propagation
+    SRT Div/Sqrt (Katherine, maybe Udeema)
+    Get riscv-arch-tests running (James, Katherine)
+    Get testfloat all passing
+    Katherine's FPU optimization
+
+Linux Boot
+    Ben, Skyler
+
+FPGA Boot Linux (Ross)
+
+IFU/LSU
+    Block diagrams, code cleanup
+    Burst mode transfers to speed up IPC
+    Implications of no byte enables on subword write - do stores take extra cycle, should this be avoided?
+
+28 nm Implementation
+    Install processor  
+    Memory macros
+    Synthesis & PNR
+    Timing review
+
+Benchmarking
+
+Flow
+    Kevin Kim has a makefile to check out and build all the pieces.  Make sure this is running; change Repo README to use his makefile
+
+Code cleanup    
+    .* fixes by thanksgiving
+    Rename top-level modules to abbreviations
+    Rename muldiv to mdu
+    Get rid of DESIGN_COMPILER flag and redundant multiplier
