Abstract: A system on a chip comprises a plurality of circuit blocks, a programmable processor and a communication circuit. Design information includes connection data including an identification of the direct mutual connection and first and second circuit blocks coupled by the direct mutual connection. An additional register is added to the system on a chip coupled to the direct mutual connection. Verification programs are used includescomprising instructions for the processor to access registers in the second one of the circuit blocks, to use the connection data, or information derived therefrom to select the first one of the circuit blocks, and to issue the standardized call to the interface program of the selected further one of the circuit blocks.

Abstract: A system on a chip comprises a plurality of circuit blocks (18), a programmable processor (12) and a communication circuit (16) coupled between the processor (12) and the plurality of circuit blocks (18), the communication circuit (16) being configured to support program controlled access to registers in the circuit blocks (18) from the processor (12), a first and second one of the circuit blocks (18) of the plurality having direct mutual connection (19) for directly passing a signal between the first and second one of the circuit blocks (18) without communication through the communication circuit (12). Design information is used that comprises connection data including an identification of the direct mutual connection (19) and the first and second circuit blocks (18) coupled by the direct mutual connection (19). An additional register is added to the system on a chip coupled to the direct mutual connection (19) to capture and/or control signals at the direct mutual connection (19).

Abstract: A receiver which includes a control circuit (7) for delivering encoded messages, derived from a radio signal, to at least one storage device (12, 28), for receiving control data, derived from the encoded messages, from at least one storage device (12, 28), and for forming a speech text for an audio circuit (69) and a display text for a display device (13) from the control data. In order to achieve an acceptable speech text quality, a speech segment memory (14) for storing predetermined speech segments of at least one language is coupled to the control circuit (7). The control circuit (7) forms a speech text with at least a part of the message for which speech segments are stored in the speech segment memory (14). The control circuit (7) is also arranged to form a display text with at least all parts of the message which are not contained in the speech text and for which no speech segments are present in the speech segment memory (14).

Abstract: A storage medium (202) carries data structures (220-222) with attribute values (224-232) for a plurality of geographical locations. On the basis of a given code the storage medium is accessed by a system in order to read the attribute values of the data structure (222) corresponding to the given code. The storage medium in accordance with the invention stores a structure description (236) which specifies the layout of the data structure (222) in attribute values. The system consults this structure description and, as a result, knows the layout of the relevant data structure. By storing the structure description on the storage medium different data structures with an individual more suitable layout can be stored. Moreover, a subsequent version of the storage medium can store an adaptation of the data structure layout while it can still be read by the original system.
