摘要： Apparatus and processes to allow voice messages to be individually and/or separately secured by a caller for playback only by an intended person or persons. The voice messages are separately secured with security information contained in a header associated with each voice message. The caller may be authorized to secure a voice message either by inputting a pre-determined authorization security code using their keypad, or based on call related information received with respect to the incoming call. The user, upon attempt to access a separately secured voice message, is prompted for input of an appropriate authorized security code to allow the access to proceed. Without proper access, a user is allowed to access (e.g., playback, delete, etc.) only non-secured voice messages.

摘要： A flexible and efficient apparatus and method of scanning switch matrix usable in user interface devices, e.g., a keypad or the like, having a number of switching elements, e.g., push buttons and/or switches, up to a twice the product of the number of rows and the number of columns. Each row and columns of the switch matrix are capable of being driven and being monitored during a scanning of the switch matrix for a presence of a closure of a switching element. The switch matrix device and the scanning method also allows integration of one or more switches in the switch matrix without the need for additional detection mechanisms dedicated to the switches.

摘要： A circular dial buffer is implemented in appropriate random access memory (RAM) accessible by a DSP for the purpose of storing DTMF digits to be generated and output on, e.g., a telephone line. To the processor, the DSP appears to behave much like an off-the-shelf stand alone touch tone dialer, with the exception that the DSP does not have access to a keypad input. Instead, in addition to speed dial capabilities, mimicked keypad input is transmitted by a controller to the DSP rather than timing information. Thus, instead of requiring the input of rows and columns or other information relating to button activation on a connected keypad to input touch tone digits, the principles of the present invention allow mimicking of keypad input using commands sent by the controller to the DSP, e.g., a first command indicating that a mimicked, manually operated key is being pressed, and a second command indicating that the mimicked key has been released. Thus, the processor in a processor/DSP telephony system is no longer required to send precisely timed start/stop commands at precise intervals for directing the timing of a DTMF generator implemented in the DSP. Instead, touch tone digit commands may be sent by the processor to the circular dial buffer in the DSP as fast as the processor-to-DSP interface will permit. Accordingly, the present invention provides for the generation of DTMF tone signals from a DSP either based on pre-programmed timing parameters for automatic dialing, but also in accordance with mimicked keypad activity transmitted from the controller to the DSP to affect a true DTMF dialer in the DSP.

摘要翻译： 循环拨号缓冲器在由DSP访问的适当的随机存取存储器（RAM）中实现，用于存储要生成并输出在例如电话线上的DTMF数字。 对于处理器来说，除了DSP无法访问键盘输入外，DSP似乎与现成的独立式音频拨号器相似。 相反，除了快速拨号功能之外，模拟键盘输入由控制器发送到DSP，而不是定时信息。 因此，本发明的原理不是要求在连接的小键盘上输入行和列或与按钮激活有关的其他信息来输入触摸音数字，而是允许使用由控制器发送到DSP的命令来模拟键盘输入，例如 指示被模拟的手动操作的键被按下的第一命令和指示模拟的键已被释放的第二命令。 因此，处理器/ DSP电话系统中的处理器不再需要以精确的间隔发送精确定时的启动/停止命令，以指导在DSP中实现的DTMF发生器的定时。 相反，触摸音数字命令可以被处理器发送到DSP中的循环拨号缓冲器，就像处理器到DSP接口将允许的一样快。 因此，本发明提供了基于用于自动拨号的预编程定时参数的来自DSP的DTMF音调信号的产生，而且还根据从控制器向DSP发送的模拟键盘活动，以影响真正的DTMF拨号器 DSP。

摘要： The present invention provides a processor device and technique having the capability of providing a two-processor solution with only one processor. In accordance with the principles of the present invention, a host processor is programmed in its native source and machine code language, and an emulated second processor is programmed in a different native source or machine code language particular to that emulated processor, to allow programming specialists in the different processors to develop common code for use on the same host processor. A multitasking operating system is included to allow time sharing operation between instructions from program code relating to the host processor (e.g., a DSP in the disclosed embodiment), and different program code relating to the emulated processor. The program code relating to the host processor (e.g., DSP) is written in program code which is native to the DSP, while the program code relating to the emulated processor (e.g., microcontroller) is written in program code which is native to the microcontroller. The SoftCore emulation module allows both DSP code and control code written for a microcontroller to execute independently on the same processor by multi-tasking resources in the faster, host processor (e.g., in the DSP), giving equal time slots of processor time to each processor (real and emulated).
