I n 1979 a contract was awarded to construct a massively parallel processor (MPP). I t w i l l be d e l i v e r e d i n the f i r s t q u a r t e r of 1983. After a brief d e s c r i p t i o n o f t h e MPP s y s t e m we w i l l d i s c u s s t h e d e s i g n o f two o f i t s u n i t s : the array unit and the staging memory. B o t h d e s i g n s w e r e h e a v i l y i n f l u e n c e d by the a l g o r i t h m s employed to p r o c e s s s a t e l l i t e images. II. SYSTEM DESCRIPTION B a s i c a l l y , t h e MPP i s a single-instruction multiple-data stream system where the s i n g l e i n s t r u c t i o n stream i s p r o c e s s e d by the array c o n t r o l u n i t and t h e m u l t i p l e d a t a s t r e a m s a r e p r o c e s s e d by the a r r a y u n i t ( A R U ) .

In order to ensure sufficient flexibility to cover a broad range of applications and algorithms, we chose an initial set of target applications for the PSC to support, including: • Signal and image processing: it is well understood that this application area has demands and opportunities well matched with the systolic paradigm [4]. • Error correcting codes: certain operations such as the GCD computation on polynomials over finite fields, Reed-Solomon coding in particular, are well suited to systolic implementation [3].
