Product Information

IA64250 Histogram/Hough Transform Processor FEATURES • • • • • Data Sheet As of Production Ver. 01 Histogram and Hough Transform Calculation Four 512 X 9 Look-up Tables Provided to Perform User-defined Point-wise Transformations Real-time Histogram Equalization High Data Rates 512 X 24 Accumulation RAM Pixel Location Function • The IA64250 is a "plug-and-play" drop-in replacement for the original LSI® L64250. This replacement IC has been developed using innovASIC’s MILESTM , or Managed IC Lifetime Extension System, cloning technology. This technology produces replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC. MILESTM captures the design of a clone so it can be produced even as silicon technology advances. MILESTM also verifies the clone against the original IC so that even the "undocumented features" are duplicated. This data sheet documents all necessary engineering information about the IA64250 including functional and I/O descriptions, electrical characteristics, and applicable timing.

There are three modes of operation for the IA64250: computation, I/O, and initialization. The controller block in the block diagram decodes the instructions and contains the mode registers. After decoding the mode, the controller generates all of the control signals to the rest of the part. These control signals include the addresses and input data for the LUT and ACC RAMs, the select lines for both the output mux and the shifter, and the reset for the FP counter. This block also controls the clearing of the ACC RAM. The ACC RAM stores the video data that is to be output during the I/O mode. This data can be modified, depending on mode, by several methods prior to being output. These methods are described in the computation mode section. The LUT RAM can store up to four different data modifying ...
