Histogram/Hough Transform Processor
Data Sheet
As of Production Ver. 01
INITIALIZATION MODE:
Initialization defines the operation of the IA64250. The mode and marker memories store
66 nine-bit words that define the operation of the part and contain marker information. The
REGADR input is used to select the proper register. Data is written over the CI bus and
read on the DO bus. The AT pin controls whether data is a mode word or a marker. When
AT is low, the data written is mode information, which is stored in the mode registers
contained in the controller block. When AT is high, the data is a marker, and is stored in the
marker memory. To prevent erroneous operation STARTIOn should be high, and IODV
and DV should be low during initialization.
