Document Summary
Using msi functions can reduce design time for complicated combinational circuits, but this approach involves a more open-ended design process. Optimized design: digital circuit design methods that minimize number of gates or chips. Structured design: digital circuit design methods that take advantage of off-the-shelf functions such as decoders, multiplexers, etc. In practice, minimizing engineering time and timeto-market is often given priority over minimizing number of gates vs. Outputs: 4-bit integer and 3-bit integer such that: e. Msi design approach: describe steps to solve problem, looking for operations that can be implemented using msi functions. Find most significant 1 in: = most significant 1 followed by next three less significant bits in, = bit position in corresponding to lsb of m. Do we need an 11-input priority encoder? is a binary integer equal to the bit position of the most significant 1 in d.
