Abstract

Introduction to the Special Issue on Application-Specific Processors Application-specific processors offer performance, energy, and cost benefits compared to their general-purpose counterparts for a wide variety of market segments, ranging from low-cost micro-controllers to high-end supercomputers. The design and usage of application-specific processors are strikingly different from general-purpose computers as the architecture is tuned to accelerate only a specific application or a class of applications. Application-specific architectures are often derived from a high-level specification of an application through a hardware/software co-design process, which can be highly automated; such a process would be inappropriate for general-purpose processor design. Moreover, code compilation targeting application-specific processors is often intertwined with the co-design process. Lastly, the system software may provide reduced and targeted functionality and interfaces at a much lower cost than a traditional embedded or real-time operating system such as iOS or Android. Historically, application-specific processors have been part of low-cost embedded devices; however, the landscape is rapidly changing. One important factor is the emergence of graphics processing units (GPUs) as general-purpose high-performance computing devices, which utilize graphics-specific hardware, but can also provide significant acceleration boosts for vectorizable applications.
