Hi,
We are pleased to announce the first public release of the StreamIt compilation infrastructure. StreamIt is a programming language and a compilation infrastructure, engineered for modern streaming systems.
To download StreamIt, or for more information, please visit:
The features of StreamIt 2.0 include:
- Language constructs that improve programmer productivity for streaming, including hierarchical structured streams, graph parameterization, and circular buffer management.
- An optimizing compiler infrastructure for the Raw microprocessor, with fully automatic load balancing, graph layout, communication scheduling, and routing.
- A robust compilation infrastructure that compiles to an ANSI C runtime library for execution on a general-purpose uniprocessor.
- A set of domain-specific optimizations for linear filters, in which each output is a weighted sum of the inputs (e.g., FIR, FFT, DCT). The analysis automatically detects linear filters and performs large-scale algebraic simplification of adjacent components, as well as automated translation into the frequency domain.
- A dynamic programming partitioner that is used for load balancing (in the Raw backend) and optimization selection (for linear optimizations). The partitioner efficiently searches a large space of hierarchical stream configurations to optimize a given metric.
- A minimal latency scheduler that leverages phased scheduling to produce a deadlock-free schedule for hierarchical stream graphs. Phased scheduling also offers a flexible tradeoff between code size and buffer size.
- A high-level stream IR (in Java) with a host of graph transformations, including graph canonicalization, synchronization removal, refactoring of parallel components, fusion of adjacent filters (running in parallel or in sequence), and fission of individual filters (into data-parallel or task-parallel components.)
- A set of benchmarks for the evaluation of streaming optimizations and architectures.
We are releasing StreamIt for both the user community and the developer community. We look forward to interacting with you as you might start to use or build upon the infrastructure.
