20090055602 | METHOD AND APPARATUS FOR EMBEDDED MEMORY SECURITY - A method and apparatus for embedded memory security is disclosed. One embodiment protects data in a memory block from unauthorized reading. When writing or reading data to or from the memory block an error correction code is used to calculate an ECC value, wherein the calculation of the ECC value is based on a combination of the data and a access identifier provided to the memory block prior to reading. The access identifier identifies the requesting program. A read error is signalled in case the calculated ECC value does not match a stored value thus indicating an access violation. | 02-26-2009 |
20090172282 | DIGITAL CIRCUITS AND METHODS FOR TESTING A DIGITAL CIRCUIT - Digital circuits and methods for testing a digital circuit are disclosed. One embodiment provides a digital circuit having a first plurality of storage elements, and a second plurality of storage elements. The digital circuit is operable in a first operation mode and in a second operation mode. In the first operation mode, the storage elements of the first plurality of storage elements operate according to their intended use within the digital circuit and the storage elements of the second plurality of storage elements are connected in series. In the second operation mode, the first plurality of storage elements is connected to the second plurality of storage elements to allow data exchange between the first plurality of storage elements and the second plurality of storage elements. | 07-02-2009 |
20100042871 | System with Configurable Functional Units and Method - A method and a system is provided for the processing of data or signals with a number of functional units which are each adapted to apply one or several functions to the data or signals, and which are connected with each other via a connection matrix for the exchange of data or signals between the functional units. At least one functional unit of the system is programmable and/or configurable such that it performs a particular function out of a number of different functions. The connection matrix is programmed and/or configured such that the functional units are connected with each other in a particular configuration out of a number of different configurations. | 02-18-2010 |
20120278520 | SYSTEM AND METHOD OF TRANSMITTING DATA BETWEEN DEVICES CONNECTED VIA A BUS DEFINING A TIME SLOT DURING TRANSMISSION FOR RESPONSIVE OUTPUT INFORMATION FROM BUS DEVICES - A device and method are provided in which the data to be transmitted is transmitted in units together with information concerning the transmission and/or the use of the data. At least some of the units include at least one region which defines a time slot within which freely selectable devices can output onto the bus data representing freely selectable information at freely selectable points in time. | 11-01-2012 |
20130097347 | SYSTEM AND METHOD OF TRANSMITTING DATA BETWEEN DEVICES CONNECTED VIA A BUS DEFINING A TIME SLOT DURING TRANSMISSION FOR RESPONSIVE OUTPUT INFORMATION FROM BUS DEVICES - Techniques and devices for transmitting data and information via a bus are provided. According to these techniques, data is transmitted in units or frames together with information that is required or useful for one or more of the transmission and the use of the data. If desired, at least some of the units or frames include a time slot within which freely selectable devices can output onto the bus data representing freely selectable information at freely selectable points in time. | 04-18-2013 |
