摘要:
A substrate for an LED assembly can have a plurality of cups formed therein. At least one cup can be formed within another cup. The cups can be co-axial with respect to one another, for example. A machined surface of the substrate can enhance reflectivity of the LED assembly. A transparent and/or non-global solder mask can enhance reflectivity of the LED assembly. A transparent ring can enhance reflectivity of the LED assembly. By enhancing reflectivity of the LED assembly, the brightness of the LED assembly can be increased. Brighter LED assemblies can be used in applications such as flashlights, displays, and general illumination.

摘要:
An integrated circuit (“IC”) package having two or more dice stacked on a substrate and electrically coupled using two or more different connection technologies may improve high-speed input/output (“I/O”) bandwidth. In an embodiment, one die is a processor and at least one other die is a dynamic random access memory (“DRAM”). One or more of the dice may be thinned and placed between the substrate and a portion of one or more of the other dice, which may be horizontally offset. One or more of the dice may be embedded in the substrate. The dice may be coupled to each other and to the substrate using a combination of controlled-collapse chip connection (“C4”) and wirebonding connection technologies. Methods of fabrication, and application of the package to an electronic assembly and to an electronic system, are also described.

摘要:
A quantization method for OFDM is described. In an embodiment, the method uses an objective function which is defined as a function of the quantization error of the OFDM signal in frequency summed over data subcarriers. A search algorithm is used to optimize the objective function and the solution found is quantized by rounding. The quantized value of the solution may then be fed back into the objective function to compute a value of that function and if the value is less than the value computed in a previous iteration of the method, the method is repeated using the quantized value of the solution as the new starting point for the search algorithm. If the value of the function is, however, not less than the value computed in a previous iteration, the new solution is discarded and the quantized value of the solution from the previous iteration is output.
摘要:
In an example, a dynamic codec allocation method is provided. The method includes receiving a plurality of datastreams and determining a respective codec loading factor for each of the datastreams. The datastreams are assigned to codecs, in order by respective codec loading factor, starting with the highest respective codec loading factor. Initially, the datastreams are assigned to a hardware codec, until the hardware codec is loaded to substantially maximum capacity. If the hardware codec is loaded to substantially maximum capacity, the remaining datastreams are assigned to a software codec. As new datastreams are received, the method repeats, and previously-assigned datastreams can be reassigned from a hardware codec to a software codec, and vice versa, based on their relative codec loading factors.
