VLIW: Dynamically Scheduled Processors

This lecture covers Very Long Instruction Word (VLIW) processors, focusing on dynamically scheduled superscalar processors and the challenges they present, such as scheduling complexity, design verification, and code bloating. It explains the difference between statically and dynamically scheduled processors, the limitations of VLIW in terms of Instruction-Level Parallelism (ILP), and techniques like loop unrolling to enhance ILP. The lecture also discusses the impact of VLIW code bloating, binary incompatibility, and the trade-offs between software and hardware optimizations. It concludes by comparing VLIW processors with standard pipelining and superscalar processors, highlighting their strengths and weaknesses.
