In order to program SIMD (single instruction stream-multiple data stream) parallel machines used for tasks such as speech and image processing, a language with explicit parallel constructs is often desirable. The language Ada, developed by the Department of Defense, is used here as a basis for such a language. Extensions of Ada, which allow the user to specify such operations as interprocessor communications and activation of processors, are proposed. These features are demonstrated by showing their use in a common speech processing algorithm, the parallel FFT.
