Interface for Microsoft Audio Compression Manager. - Delphi Source The ACM uses existing driver interface hooks to override the default mapping algorithm for waveform audio devices. This allows the ACM to intercept device-open calls. After a call has been intercepted, the ACM can perform a variety of tasks to process the audio data, such as inserting an external compressor or decompressor into the sequence.

The Radio Interface Layer is the name for an interface that was developed especially for the Pocket PC Phone Edition. It is meant to abstract the interface with a phone/modem device. To achieve this it is closely modelled after the GSM AT command interface. Unfortunately the API was not published officially by Microsoft. Instead more high level API s were published that should be sufficient for developers. Again, unfortunately they are not sufficient. For example the API for receiving notification of incoming SMS messages is arranged for exclusively for one application per type of SMS. Apparently this will be improved upon in Pocket PC 2003. Another area is the availablity of a true AT command modem interface to interact with the GSM modem directly, which is also absent.

Realizing an MP3 player with the LPC2148, using libmad and EFSL This Application Note describes how to integrate the libmad MPEG 1/2 layer 3 library and the Embedded File System Library EFSL in a LPC2148 device to realize MP3 player. The Keil MCB2140 board is used to test the application and the Rowley CrossStudio for ARM has been chosen as a reference tool-chain.

The FM24C256/C256L/C256LZ devices are 256 Kbits CMOS nonvolatile electrically erasable memory. These devices offer the designer different low voltage and low power options. They conform to all requirements in the Extended IIC 2-wire protocol. Furthermore, they are designed to minimize device pin count and simplify PC board layout requirements.

The USB Multi-Interface driver is a replacement driver for the system provided Multi-Interface driver. This driver was developed to overcome some bugs that are included in the build in driver and to introduce new features. The driver is compatible to the system provided Multi-Interface driver. If the driver is installed on a system, it does not automatically replace the system provided driver. It exists parallel to the system driver and is assigned to a device during the installation process.

This application note explains the process of eveloping and debugging a hardware abstraction layer (HAL) software device driver, to aid device driver development for the HAL of the Altera Nios® II system. The various software development stages are illustrated using the Altera_Avalon_UART as an example hardware device, and an example of a HAL software device driver called my_uart.

The SP2526A device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low on-resistance (110mΩ typical) and can supply 500mA minimum. The fault currents are limited to 1.0A typical and the flag output pin for each switch is available to indicate fault conditions to the USB controller. The thermal shutdown feature will prevent damage to the device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the device will remain off unless there is a valid input voltage present.

The recent developments in full duplex (FD) commu- nication promise doubling the capacity of cellular networks using self interference cancellation (SIC) techniques. FD small cells with device-to-device (D2D) communication links could achieve the expected capacity of the future cellular networks (5G). In this work, we consider joint scheduling and dynamic power algorithm (DPA) for a single cell FD small cell network with D2D links (D2DLs). We formulate the optimal user selection and power control as a non-linear programming (NLP) optimization problem to get the optimal user scheduling and transmission power in a given TTI. Our numerical results show that using DPA gives better overall throughput performance than full power transmission algorithm (FPA). Also, simultaneous transmissions (combination of uplink (UL), downlink (DL), and D2D occur 80% of the time thereby increasing the spectral efficiency and network capacity
