2
Brief description of the paper content

• Briefly, what is the paper discussing?
• What is the motivation for this work?
• Describe the structure of the MorphoSys
  architecture

3
Taxonomy for Reconfigurable Systems

• What paradigm is MorphoSys 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/reconfigurab
  ility/interface/computation models).

4
Taxonomy for Reconfigurable Systems

• Discuss Table I and Table II.
• Explain the differences between SIMD array
  processors and SIMD-based reconfigurable systems.

5
MorphoSys 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?

6
MorphoSys Architecture

• Frame Buffer
• What specific instructions were introduced for
  the programmable processor?

7
MorphoSys Architecture

• Discuss the instructions in Table 3. What is
  overlap of computation and data transfers? What
  are its merits? Limitations?
• What is the operation mode? What parallel
  operation do take place during operation?

8
Design of Components

• What is the structure of an Reconfigurable Cell
  (Figure 5)?
• Context Register. Discuss Figure 6.
• Context Memory Organization. Context Broadcast.
  Dynamic Reconfiguration. Selective Context
  Enabling.

9
Design of Components

• Interconnect network. What hierarchical levels
  are there in the network?
• Summarize the architectural features of
  MorphoSys. Compare with Pleiades. Discuss
  advantages and limitations.
