摘要: A resistive element is connected in series to a cathode terminal of an LED light source at a last stage (or an anode terminal of an LED light source at a first stage) of an LED chain, and a resistance value of the resistive element is configured to be variable in resistance value in accordance with a variation of voltage drops of the LEDs connected in series so that a resistance value of a resistive element connected to an LED chain having a large voltage drop has a smaller resistance value then a resistance value of a resistive element connected to an LED chain having a small voltage drop. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements.

摘要: When an error is detected in an error detecting unit in a processor system, the error detecting unit outputs an error signal to an interrupt control unit, and the interrupt control unit outputs a value of an error address register and a control signal to a program counter control unit and rewrites a value of a program counter to a value of an error address register. By this means, the branching process by an error interrupt is realized. In this case, when the error is detected, the process of saving the value of the program counter at the time of error occurrence is not performed, and a specific save register and a control circuit for the recovery to the address at the time of the error occurrence after the end of the error processing are not provided.

摘要: Security threats are reduced by providing a TLB in a bus interface unit of a media processor whose contents can be updated only from inside the media processor. The TLB checks whether an address specified by an external access request falls within access-permitted areas registered in it. If it does, an access request from outside is passed on to an inside of the media processor; otherwise, it is rejected.

摘要: The present invention provides a technique for changing the number of taps in filter processing without the need for execution of branch processing. A filter processing device comprises: an arithmetic circuit that performs arithmetic processing for filtering operation; an internal register that retains data to be subjected to arithmetic processing in the arithmetic circuit and that receives the result of arithmetic processing from the arithmetic circuit as data to be written back thereto; and a data generator that generates data to be fed to the arithmetic circuit through use of the data retained in the internal register. Further, in the filter processing device, there is disposed a tap number control circuit that is capable of controlling the number of taps in filter processing according to a tap control signal applied thereto. In this configuration, no branch processing is required for controlling the number of taps by the use of the tap number control circuit.
