Abstract: A dual-phase approach to red eye correction may prevent overly aggressive or overly conservative red eye reduction. The dual-phase approach may include detecting an eye portion in a digital image. Once the eye portion is detected, the dual-phase approach may include the performance of a strong red eye correction for the eye portion when the eye portion includes a strong red eye. Otherwise, the dual-phase approach may include the performance of a weak red eye correction for the eye portion when the eye portion includes a weak red eye. The weak red eye may be distinguished from the strong red eye based a redness threshold that shows the weak red eye as having less redness hue than the strong red eye.

Abstract: Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. Thermal noise in a sideband may be measured and used as an estimate of thermal noise in a signal band. In one design, samples containing a desired signal centered at DC or a frequency higher than DC may be partitioned into blocks of K samples. Each block of K samples may be transformed with an FFT to obtain a corresponding block of K transform coefficients for K frequency bins. The power of transform coefficients for frequency bins in the sideband may be computed. Thermal noise may be estimated based on power values for the frequency bins in the sideband. Power values for frequency bins in the signal band may also be obtained and used to estimate total received power. RoT may then be estimated based on the estimated thermal noise and the estimated total received power.

Abstract: Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. In an aspect, thermal noise in a sideband may be measured and used to estimate thermal noise in a signal band. In one design, received power in the sideband may be measured, e.g., by computing total power of FFT transform coefficients within the sideband. Thermal noise may be estimated based on (e.g., by filtering) the measured received power in the sideband. Received power in the signal band may also be measured. Total received power may be estimated based on (e.g., by filtering) the measured received power in the signal band. RoT may then be estimated based on the estimated thermal noise and the estimated total received power. The estimated RoT may be used to estimate an available load for a cell, which may be used to admit and/or schedule users in the cell.

Abstract: There are various methods of securing programs and data on a processor. The external address enable pin of the processor is sampled upon a power-on or reset to the processor, to determine whether or not accesses to external memory are allowed. Other changes to the external address enable pin are thereafter ignored. In addition, if it is determined that an internal memory access is occurring, the contents of such an access can be masked to prevent unauthorized viewing of the memory contents via an external memory bus. In addition, a programmable security bit may be set to disable the dumping of flash memory contents, allowing only the erasing of the flash memory.

One disclosed embodiment provides a method of performing an iterative non-blind deconvolution of a blurred image to form an updated image. The method comprises downsampling the blurred image to form a blurred image pyramid comprising images of two or more different resolution scales, downsampling a blur kernel to form a blur kernel pyramid comprising kernels of two or more different sizes, and deconvoluting a selected image in the blurred image pyramid according to a Richardson-Lucy deconvolution process in which a bilateral range/spatial filter is employed.

Abstract: Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

Abstract: A method and apparatus is provided for that includes an improved special function register (SFR) access scheme by using a clock tree distribution process. In accordance with an exemplary embodiment, a conditional SFR write strobe signal may be used to trigger the SFR registers. A clock tree distribution process may be used to achieve significantly higher system speed. When balancing the clock network of the system, the clock leaf of the flip-flop or other circuit element that generates the SFR write strobe signal may be “advanced” by connecting the circuit element directly to the clock root. In addition, the SFR write strobe signal distribution may be balanced as a separate clock tree with minimum insertion delay.

In particular, the configuration bit allows the microprocessor user to establish the computer port as a memory port, input/output port or the like. The configuration bit is provided to the computer port at system power up or reset. Moreover, the configuration bit may be stored in flash memory and provided to the microprocessor computer port or, in the alternative, the configuration bit may be provided to the computer port directly via the microprocessor bus interface.

Abstract: An improved high performance scheme is provided with a serial peripheral interface (SPI) to enable microcontroller-based products and other components and devices to achieve a higher serial transmit and receive data rate. An exemplary technique utilizes a CPU and an SPI having a circular FIFO structure. To prevent the memory traffic associated with any SPI accesses from conflicting with other CPU memory accesses, the technique utilizes cycle stealing direct memory access techniques for SPI data transfers with the memory. During a CPU read/write sequence, data is read/written from/to the memory through a virtual special function register (SFR). Once the virtual SFR access is detected, all accesses are redirected to the circular FIFO buffer memory, with no additional pipelining necessary. The CPU pointers can suitably increment as appropriately controlled by hardware.
