+but I will highlight the most important challenges and tradeoffs.

+In general, the most important tradeoff seems to be between flexibility and
+everything else (code size, performance, complexity). This flexibility is
+expressed in which instructions are possible, which connections are present, how
+big register files are, etc.
+
+An important reason to be flexible is for programmability. If the hardware is

 spend a few words on the observed merits of hardware/software codesign.
