| Abstract: | A simple X-ray TV picture freezer, with just 5 chips of LSIC, is discussed in this paper. Its VRAM block is made up of cheap and relatively lower speed large scale SRAM. The memory block works in alternate mode and can meet the sample speed up to 10-12 Msps and the pixel matrix of 512 x 512. |
