System which cooperatively uses a systolic array processor and auxiliary processor for pixel signal enhancement

摘要: A Lofargram Enhancement System having a processor 1 to i rows and j columns of processing elements or data cells. Each cell has location corresponding an index, computational capability memory means for storing pixel intensity value. The cells all are addressed concurrently. FIFO receives stores scan line comprising sequence signal values. program provides calculating row column total values the stored in predetrmined relationally related each respective element systolic processor. An auxiliary reads totals jth loads first with corrected Column selection timing control circuit shifts contents bottom into Output delivery recorder as data, sequentially right array one actuates calculate enter element, until elements, rightmost being loaded output value is entered. down shifted preparation then receiving next data.
