For an initial estimate of the module partitioning, use the open-queue model setting r» .5. This is subject to large errors, so it is useful as an initial partitioning estimate only. |

In general, use the d-binomial model for pipelined processor-memory configurations. |

Consider a 50 MIPS processor (Dt = 20 ns), requiring 75 MAPS, using m = 16 and n = ls Tc = 75 ´ 106´ 0.1 ´ 10-6 = 7.5. Assume IF/cycle = 0.8, DF/cycle= 0.5, DS/cycle= 0.2. |

This is a simple pipelined processor. We use the d-binomial approximation for performance estimates. Compute d: |
