摘要： A chain of processing element (10a, 10, 10b) with a logic circuit (14) and a storage element (12) is provided. The storage elements (12) of all except a final processing element (10b) in the chain have one or more outputs coupled to the logic (14) of a next processing element (10a, 10, 10b) in the chain. A timing circuit (16) controls respective loading time points at which the storage elements (12) load data from the logic circuits (14) in respective ones of the processing elements (10a, 10, 10b). The data is loaded progressively later in processing elements (10a, 10, 10b) that successively precede one another in the chain. The time interval between successive loading time points of the final processing element (10b) includes loading time points of loading all processing elements (10a, 10) other than the final processing element (10).

摘要： The present invention relates to a memory circuit and a method of controlling data retention in the memory circuit, wherein a supply signal is selectively switched to a respective one of at least two virtual supply lines (24) each shared by a respective one of a plurality of groups (30-1 to 30-n) of memory cells (C0,0 to Cy,z). The selective switching is controlled based on a global activity control signal (A), used for setting the memory circuit either into a standby state or into an active state, and a local data retention indication signal (DR1 to DRn) allocated to a dedicated group of memory cells. Thereby, the data retention part of the memory circuit can be adapted to the application and its state, and standby mode leakaged power is only dissipated in those memory cells for which data retentions actually required.

摘要： A location system including a base station (120, 200) and a responder tag (140, 250) that communicate using an acoustic signal to determine the location of the tag in a bounded 3D space (100). The base station transmits a request signal (310) encoded with the identifier of a particular tag. The particular tag responds after a fixed delay (t2−t1) with an acoustic response signal (330). The base station determines the location of the tag based on the received line of sight signal (330) and its reflections (340). The response signal may be encoded with data indicating a status of the tag, or data from associated sensors (270) or actuators (280). The request signal may also be encoded with data for controlling the tag or the associated sensors and actuators. A power management scheme may be carried out by the tag.

摘要： 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. The elements of this configuration word represent the weighting factors which are used to select or deselect a basic-code vector. The selected basic-code vectors are added together and the result of the weighted sum operation is then output as an intermediate-code vector. Subsequently, the intermediate-code vectors are added together by an add unit and output as a composite-code vector. The ability to make selections out of a plurality of incoming basic-code vectors and to add intermediate-code vectors into a composite-code vector, together with the ability to configure the operations of the functional units of the device by means of configuration words, increases the flexibility of the device significantly. This flexibility is needed to support a variety of transmission standards.

摘要： The present invention relates to a memory device comprising a memory (EM) having at least two predetermined register memory sections addressable by respective address ranges AS1-ASz) and at least one access port (P1-PZ) for providing access to said memory (EM). Furthermore, access control means (A) are provided for addressing said memory (EM) so as to operate said register memory sections as shift registers and to map shift register accesses of the at least one access port (P1 to PZ) to predetermined addresses in the global address space of the memory (EM). In this way, it is possible to combine a plurality of FIFO memories in a single addressable memory device. This implementation is favourable in view of power consumption and area. Furthermore, by introducing a buffer memory, a multi-port memory device can be replaced by a single-port memory device of the same capacity. This advanced implementation also provides a reduced cycle and access time.
