摘要:
A memory access technique is provided that may be used in WLAN (Wireless Local Area Network) communication devices. An on-chip memory has multiple memory circuits forming individually addressable memory segments. An arbitration unit arbitrates between multiple requesters, each requesting access to the on-chip memory. The requesters are on-chip circuits and/or external devices. The arbitration unit determines a memory circuit to be accessed for each request that is received from a requester. The determination may be based on a software configurable arbitration scheme. The memory segments may form a bank of single-port SRAM (Static Random Access Memory) devices.

A method of payment using a client device is disclosed. The payment can be made through a payment method service that can control the payment flow and options available to the user of a client device. Using the payment method service, new payment options with new data schemas and/or new process flows can be used by the client device, but without any need to update software stored on the client device. The payment method service can utilize the look and feel of the client device, such that the user views payment options in the native UI of the client device.
摘要:
A digital compensation of an input stage of a comparator may be achieved by providing switched load elements, which may be appropriately connected to the differential input pair of the comparator in order to match transistor characteristics of the input pair and also match the load value of the input stage. Thus, enhanced offset behavior may be accomplished without providing an external signal and/or without requiring complex reference voltages/currents.
摘要:
In a memory area having portions of predictable access frequency, such as in a memory area of a real time clock unit, a synchronous design may be implemented by associating storage cells of identical access frequency with a clock gating mechanism, thereby reducing power consumption. Hence, the synchronous design of the real time clock unit may provide reduced implementation effort and enhanced verification capability.
摘要:
A communication device for performing cryptographically secured communication in a WLAN (Wireless Local Area Network) network is provided that comprises a security enhancement unit and a MAC (Medium Access Control) unit. The security enhancement unit is for encrypting plaintext data frames into encrypted data frames and/or decrypting encrypted data frames into plaintext data frames. The MAC unit is for managing communication between communication devices within the WLAN network by coordinating access to a shared wireless communication medium through which communication signals are transmitted. The security enhancement unit and the MAC unit are adapted to perform an on-the-fly encryption process and/or on-the-fly decryption process thereby exchanging the encrypted data frames without buffering the encrypted data frames after encryption or prior to decryption, respectively. The embodiments may provide an improved encryption/decryption architecture including an on-chip memory for performing on-the-fly encryption and/or on-the-fly decryption in the framework of 802.11i security enhancement.
摘要:
A method of performing encrypted WLAN communication is provided that comprises the steps of performing a connection set-up for the encrypted WLAN communication and performing data frame encapsulation and/or decapsulation during the encrypted WLAN communication. The connection set-up is performed by executing software-implemented instructions, and the data frame encapsulation and/or decapsulation is performed by operating single-purpose hardware. In embodiments, corresponding single-purpose hardware devices, integrated circuit chips, computer program products and computer systems are provided. The embodiments may provide an improved hardware/software architecture for 802.11i security enhancement.
摘要:
Card applets associated with an electronic wallet are activated and deactivated based on user-defined rules. Based on the rules and a device state, a card emulation state and card applet states are modified to enable or disable completion of transactions. The transactions are between a computing device and a reader such as a point-of-sale terminal. In some embodiments, a user designates a plurality of the card applets as fast cards capable of completing a transaction via near-field communication (NFC) interaction without user input at a time of the transaction.
摘要:
An integrated circuit including a first power rail, a second power rail, a power clamp connected between the first and second power rails; and a trigger circuit connected to the power clamp and the first second power rails. The trigger circuit includes an RC element formed on the basis of field effect transistors, first inverter stage connected to the RC element, a second inverter stage, and a third inverter stage. The first, second and third inverter stages are connected in series to a control input of the power clamp. The trigger circuit also included a feed back connection from an output of the second inverter stage to the first inverter stage.
摘要:
A simplified notification scheme that looks at past behavior of accepting or rejecting messages and modifies whether and/or how future similar notifications are displayed. For example, if a user consistently ignores or rejects a pop-up notification, the system can modify whether or not such a pop-up notification is displayed again. In one specific embodiment, a wireless network can be detected by a mobile phone. The phone can determine whether or not a pop-up notification related to the wireless-network detection should be displayed based on past behavior of the user.
摘要:
In an analog circuit portion, a systematic mismatch between a plurality of circuit elements may be reduced in view of a technology gradient by appropriately positioning the unit devices of the circuit elements so as to obtain a similar response of the circuit elements with respect to the gradient. For example, the spatial relationship of adjacent unit devices belonging to the same circuit element along an arbitrary lateral direction may be the same as the spatial relationship of adjacent unit devices of another circuit element.
