  1. ESE 566: Hardware/Software Co-Design of Embedded SystemsFall 2005 Instructor: Dr. Alex Doboli. Paper discussed in class: H. Singh, M.-H. Lee, G. Lu, F. J. Kurdahi, N. Bagherzadeh, E. M. Chaves Filho, “MorphoSys: An Integrated Reconfigurable System for Data-Parallel and Computation-Intensive Applications”, IEEE Transactions on Computers, Vol. 49, No. 5, May 2000, pp. 465-481.

  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/reconfigurability/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.
