MC68000 microprocessor

Several experiments were done to evaluate SUGAR. Designs for the MCS6502 and MC68000 microprocessors generated using different... 

Three experiments were done with the MC68000 microprocessor one of which (S4) is described in this section. Descriptions of the other two experiments can be found in [Rajan88]. 

System overview, design representations, transformations, architectural partitioning, scheduling, data path synthesis, microprocessor synthesis, a fifth-order digital elliptic wave filter example, a Kalman filter example, the BTL310, the MCS6502, and the MC68000. 

SUGAR uses a style-specific synthesis method for the microprocessor design style. The method synthesizes even large microprocessors like the MC68000 rapidly in only 80 CPU minutes on a VAX 8800. Although definite conclusions in favor of the style-specific... 

SUGAR contains knowledge about microprocessor interconnections represented as a set of bus models that can be used to synthesize busses top-down. Two bus models, namely, the IBM Micro 370 and the Motorola MC68000 bus models were implemented. Experimental comparisons of top-down synthesis of busses using fixed bus models with bottom-up synthesis of busses suggest that top-down synthesis of busses with fixed bus models results in designs with better interconnections. 

The MC68000 is a general purpose microprocessor. Its 40 page ISPS is too big for the general synthesis path. Therefore, only SUGAR results are given here for this architecture.
