Taxonomy for Reconfigurable Systems • What paradigm is Morpho. Sys proposing? How is this similar/different from the ideas in Pleiades? • What criteria are used to analyze a reconfigurable system? Discuss these criteria (granularity/depth of programmability/reconfigurability/interface/computation models).

Taxonomy for Reconfigurable Systems • Discuss Table I and Table II. • Explain the

Taxonomy for Reconfigurable Systems • Discuss Table I and Table II. • Explain the differences between SIMD array processors and SIMDbased reconfigurable systems.

Morpho. Sys Architecture • Discuss the Reconfigurable Cell Array (Figure 3). Structure. Reconfiguration modes.

Morpho. Sys Architecture • Discuss the Reconfigurable Cell Array (Figure 3). Structure. Reconfiguration modes. What is the correlation between application domain and this structure? • What activities does the programmable processor perform?
