Abstract: An RGB digital video signal destined to be displayed on a display such as a liquid crystal display (LCD) is converted from the RGB colour space to the YUV colour space. The signal converted into the YUV colour space is subjected to at least a processing operation selected among a sub-sampling operation (24) and a data compression operation (26). The signal is then stored in a memory and the signal read from said memory (12) is then subjected to at least a return operation (28, 30) complementary to the aforesaid processing operation (24, 26). The signal subjected to the aforesaid return operation is lastly reconverted from the YUV colour space to the RGB colour space, thus being susceptible to be displayed on the display.

Abstract: The invention relates to a circuit architecture and a relevant method for performing a trimming operation directly on an application board, or after the operation of packaging integrated electronic devices. The circuit architecture of this invention comprises at least one non-volatile memory unit (3) having non-volatile memory elements (5) and a means (17,19) for modifying the state of the memory elements (5), a first multifunctional input pin (8) whereon a sequence (25) of trimming data is received, a second multifunctional input pin (9) whereon a timing signal of the trimming operations is received, and an additional access pin (7) for switching the circuit architecture operation from the normal mode over to the trimming mode. This circuit architecture further comprises a volatile memory unit (2) associated with the non-volatile memory unit (3) for storing up the non-volatile memory (3) state at power-on or at the simulating phase, and storing up the sequence (25) of trimming data at the programming phase; an interface (6) is provided between said pins (7,8,9) and the memory unit (2,3) for initially storing the data sequence (25) into the volatile memory unit and subsequently timing the trimming operation.
