TL;DR: The StreamIt language provides novel high-level representations to improve programmer productivity and program robustness within the streaming domain and the StreamIt compiler aims to improve the performance of streaming applications via stream-specific analyses and optimizations.

TL;DR: The Raw microprocessor research prototype uses a scalable instruction set architecture to attack the emerging wire-delay problem by providing a parallel, software interface to the gate, wire and pin resources of the chip.

TL;DR: A systematic model of the tradeoff space fundamental to stencil pipelines is presented, a schedule representation which describes concrete points in this space for each stage in an image processing pipeline, and an optimizing compiler for the Halide image processing language that synthesizes high performance implementations from a Halide algorithm and a schedule are presented.

TL;DR: The most radical of the architectures that appear in this issue are Raw processors-highly parallel architectures with hundreds of very simple processors coupled to a small portion of the on-chip memory, allowing synthesis of complex operations directly in configured hardware.

TL;DR: This work introduces program shepherding, a method for monitoring control flow transfers during program execution to enforce a security policy, and implements these capabilities efficiently in a runtime system with minimal or no performance penalties.
