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.

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

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).

Taxonomy for Reconfigurable Systems

  • Discuss Table I and Table II.

  • Explain the differences between SIMD array processors and SIMD-based reconfigurable systems.

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?

MorphoSys Architecture

  • Frame Buffer

  • What specific instructions were introduced for the programmable processor?

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?

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.

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.
