Abstract :
Kestrel is a programmable linear systolic array processor designed for sequence analysis. Among other features, Kestrel includes an 8-bit word, a single-cycle add-and-minimize instruction, and efficient communication using systolic shared registers. This paper describes Kestrel´s functional units in detail, and examines each of their effects on system performance. With prototypes currently in progress, we expect to complete a full Kestrel array, with between 512 and 1024 processing elements, by 1997
