摘要： An apparatus and method are described to increase the control resolution of an electronic device. In one embodiment, the invention includes a spread pulse modulation module to generate a first set of bits based on a second set of bits that is larger than the first set of bits. The spread pulse modulation module modulates the least significant bit (LSB) of the first set of bits based on information including the LSB modulation period and the LSB modulation duty cycle. The spread pulse modulation module also modulates the least significant bit of the first set of bits so that the least significant bit transitions at least twice from a high value to a low value during the modulation period. This embodiment of the invention also includes a digital-to-analog conversion module to generate an analog input signal to the electronic device based on the first set of bits.

摘要： A versatile analog front end and timing generator (AFE/TG) integrated circuit is capable of supplying horizontal and vertical timing signals to a large number of disparate image sensors. In a first novel aspect, the AFE/TG includes an output mode wherein multiple identical AFE/TGs output digitized sensor data to a single digital image processor (DIP) without intervening multiplexing circuitry. In a second novel aspect, the AFE/TG includes a processor that executes a program. Execution of the program controls the detailed timing of horizontal and vertical timing signals output from the AFE/TG. At boot time, the program is loaded into the AFE/TG via a serial bus. In a third novel aspect, the processor is clocked by a clock signal with a relatively long clock period. A DLL and associated set/reset circuitry allows the processor to generate and control timing signals with a resolution substantially greater than clock period of the processor.
