Title: Memory element for a wafer scale integrated circuit
Inventor: CHAMBERLAIN JOHN TERENCE
IPC: G11C5/06
Filed: 1983-05-03
Abstract: A rapid retrieval associative memory is provided allowing named data in a chain of data registers 52x, 52y to be withdrawn on presentation of a maskable naming word to an access register chain 54x, 54y. Masking is controlled by bits fed to a control register chain 56x, 56y. Flip- flops 152x, 152y are reset by a signal G1 and each is set by a bit pattern "10" on the output and input of the respective control registers 56x, 56y. The flip-flops 152x, 152y are reset by mismatch detected by respective gates 150x, 150y. A control bit pattern "11" causes a cross-over switch 50x, 50y associated with a set flip-flop 152x, 152y to operate to supply the required data from data register chain 52x, 52y to access register chain 54x, 54y for supply to the memory output. <IMAGE>

Title: Image processing system
Inventor: KELLAR PAUL RODERICK NOEL
IPC: H04N5/14
Filed: 1984-04-09
Abstract: A system for processing images typically still images from a slow scan source such as associated with an electron microscope, which images are to be displayed at a higher scan rate. The analogue source converts analogue input signals into digital form via an ADC 20 and passes them via an adder 31 to a framestore 32. An output of the framestore is also received by the adder. The capacity of the framestore is sufficiently large to accommodate several hundred summed frames. The image is built up by using all the stored information and all the incoming information. A divider 33 under the control of a frame counter 34 automatically corrects for intensity as the summation of frames progresses, the result being available for monitoring via a digital to analogue converter 25. Additional mechanisms are disclosed for dealing with other aspects associated with differing frame rates. <IMAGE>
