Episode notes
RISC and Efficiency
- RISC architecture's success is tied to the increasing demand for efficiency in computing.
- This is driven by battery-powered devices and the ubiquity of low-cost processors.
Moore's Law and Heterogeneity
- Moore's Law is slowing, pushing for a rethink of computation and efficiency.
- Heterogeneous computing, with specialized processors, is becoming more important.
Software's Role in Heterogeneous Computing
- Heterogeneous computing requires programmers to understand hardware better for efficiency.
- This shifts the responsibility of optimization from hardware to software.
