IEEE Computer Architecture Letters is a rigorously peer-reviewed forum for publishing early, high-impact results in the areas of uni- and multiprocessor computer systems, computer architecture, microarchitecture, workload characterization, performance evaluation and simulation techniques, and power-aware computing. Submissions are welcomed on any topic in computer architecture, especially but not limited to: microprocessor and multiprocessor systems, microarchitecture and ILP processors,  workload characterization, performance evaluation and simulation techniques, compiler-hardware and operating system-hardware interactions, interconnect architectures, memory and cache systems, power and thermal issues at the architecture level, I/O architectures and techniques, independent validation of previously published results, analysis of unsuccessful techniques,  domain-specific processor architectures (e.g., embedded, graphics, network, etc.), real-time and high-availability architectures, reconfigurable systems.

LCA is a semi-annual forum for fast publication of new, high-quality ideas in the form of short, critically refereed, technical papers. Submissions are accepted on a continuing basis, and accepted letters will be published immediately in the IEEE Digital Library and in the next available print issue. Members of the Technical Committee on Computer Architecture will receive the print issue as a benefit of being a member. Authors should submit their manuscript through ScholarOne Manuscripts.
