DASS: Combining Dynamic & Static Scheduling in High-Level Synthesis

Paolo Ienne, Lana Josipovic

A central task in high-level synthesis is scheduling: the allocation of operations to clock cycles. The classic approach to scheduling is static, in which each operation is mapped to a clock cycle at compile-time, but recent years have seen the emergence o ...

When and why performance goals predict exploitation behaviors: An achievement goal complex analysis of the selection function of assessment

Fabrizio Butera, Hamza Sehaqui, Kevin Fahrni, David Nguyen, Martin Jobin, Nicolas Sommet

We adopted an achievement goal complex framework (studying achievement goals and reasons connected to goals) to determine when and why performance goals predict exploitation of others' knowledge. We hypothesized that: (i) when selective assessment is used ...
