Abstract: An array of data values, such as an image of pixel values, is stored in a main memory (12). A processing operation is performed using the pixel values. The processing operation defines time points of movement of a multidimensional region (20, 22) of locations in the image. Pixel values from inside and around the region are cached for processing. At least when a cache miss occurs for a pixel value from outside the region, cache replacement of data in cache locations (142) is performed. Locations that store pixel data for locations in the image outside the region (20, 22) are selected for replacement, selectively exempting from replacement cache locations (142) that store pixel data locations in the image inside the region. In embodiments, different types of cache structure are used for caching data values inside and outside the region. In an embodiment the cache locations for pixel data inside the regions support a higher level of output parallelism than the cache locations for pixel data around the region.

Abstract: An analog electronic circuit is proposed that e.g. computes the symbol likelihoods for PAM or QAM signal constellations. The circuit has at least one set of M transistors connected to a common current source. A multiplier/adder generates the voltages to be applied to the transistors from a value y and a set of M expected values in such a way that the currents through the transistors correspond to the likelihood that the value y corresponds to the expected values. The circuit can be used for signal demodulation and various other applications.

Abstract: A processor includes a memory port for accessing a physical memory under control of an address. A processing unit executing instructions stored in the memory and/or operates on data stored in the memory. An address generation unit (“AGU”) generates address for controlling access to the memory; the AGU being associated with a plurality of N registers enabling the AGU to generate the address under control of an address generation mechanism. A memory unit is operative to save/load k of the N registers, where 2<=k<=N, triggered by one operation. To this end, the memory unit includes a concatenator for concatenating the k registers to one memory word to be written to the memory through the memory port and a splitter for separating a word read from the memory through the memory port into the k registers.

Abstract: Configurable vector processors can be equipped with code generators, so that they are capable of handling different standards and codes. Furthermore, they can be arranged to provide support for related functions such as cyclic redundancy check (CRC). A configurable vector processor would then be equipped with a plurality of generators which generate basic codes in vector format. However, a disadvantage of such a configurable vector processor is that it cannot provide a composite code which is dependent on such basic codes. This is necessary if the configurable vector processors should be flexible enough to support a variety of CDMA-like standards. The device according to the invention is provided with at least two weighted sum units, which are able to make a selection out of a plurality of incoming basic-code vectors by means of a weighted sum operation, under the control of a configuration word.

Abstract: A voltage controlled oscillator (600) includes a voltage to current portion (400) that is inversely proportional to the semiconductor processing in order to compensate for variations both in the low-frequency and high-frequency portions of the VCO gain response. To compensate for low-frequency variations, a portion of the control current (ICTL), non-compensated control current ICTLNC (436), is subtracted from a reference current IREF (408) and the result, a low-frequency compensating control current, ICTLLF (438), is added to the non-compensated control current ICTLNC (436). To compensate for high frequency variations, a number of differential transistor pairs (410-416) are provided that have tail currents that are inversely proportional to the processing. One input (426) to all the differential pairs is connected to the VCO's control voltage while the other inputs (418-424) are connected to successively increasing voltages in the control voltage range.
