Yeah, the only solution I could think of was an FPGA... It would have to be a nice one, since one would need to configure the FPGA to also do the display. Although a fast micrcontroller/processor (>75-100MIPs?) could do the display, if it was dual port SRAM (one side writes, the other reads). Then this begs the issue of synchronization (Is the bufer the processor is displaying, being overwritten as it displays?) Then you get into all different choices of burst reading, double (ping-pong) buffering the data, multi-sampling points...etc. *sigh*
Although alexanders is planning on a TV display, which opens a whole different can of worms, in terms of speed issues. A PIC18 maybe fast enough for a black/white semi-low resolution, but would have to be spoon-fed data read to be displayed. Although this doesn't answer the question of who's taking the measurements? Also have you given any thought as to signal conditioning? (i.e. range detection...etc.)
