摘要： Techniques for performing data tracing in an integrated circuit with multiple embedded memories are described. A trace module within the integrated circuit forms packets of trace data for memory accesses of the multiple memories. The trace module includes multiple data capture units (one for each memory) and a trace stream generator. Each data capture unit includes a register, a comparator, an address compressor, a data compressor, and a packetizer. The register stores an address for a prior memory access of the associated memory. The comparator compares an address for a current memory access against the address stored in the register. The address and data compressors perform address and data compression, respectively, for the current memory access. The packetizer forms a packet of trace data for the current memory access. The trace stream generator generates a stream containing trace data packets from all data capture units.

摘要： A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line fax machines is described. To process a fax, a source interface waits until an interface to a destination fax machine has been established before establishing an interface to a source fax machine. The source fax transmission rate must be less than or equal to the destination fax transmission rate and the data rate of the digital channel. To establish the source fax interface at the proper rate, the source interface first selects and initial data rate from a set of standard fax transmission rates. The source interface sends unacceptable rate (failure to train) messages to the source fax machine until the source fax transmission rate is less than or equal to the data channel rate and the destination fax transmission rate. During fax processing, the destination interface inserts non-printing data (fill bits) if the destination fax transmission rate is greater than the source fax transmission rate. Fill bits are also inserted to compensate for transmission delays.

摘要： A switch (212) is included in a wireless terminal (206). Different settings of the switch cause a processor (210) in the wireless terminal to use different device algorithms. The switch itself is set by applying a code signal to the wireless terminal through its RJ-11 interface (208). The code is a sequence of Dual Tone Multiple Frequency (DTMF) tones, which may conveniently be provided by an ordinary telephone (214), or by a computer modem (204). A single wireless terminal may therefore be reconfigured on demand to interface with any of a variety of devices (202), (214).
摘要翻译：开关（212）包括在无线终端（206）中。交换机的不同设置使无线终端中的处理器（210）使用不同的设备算法。通过其RJ-11接口（208）向无线终端应用代码信号来设置开关本身。代码是双音多频（DTMF）音调的序列，其可以方便地由普通电话（214）或计算机调制解调器（204）提供。因此，可以根据需要重新配置单个无线终端以与各种设备（202），（214）中的任一个相连接。

摘要： A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line telephones and analog wire line fax machines is disclosed. During a telephone call, a fax detector monitors the incoming data for fax signals. If a fax is detected, the data processor switches from processing the data as if it were voice to processing it as fax. In addition, the remote station is sent a signal notifying it to process the data as fax rather than voice. The fax detector operates by detecting the preamble of a V.21 message, present at the beginning of every fax call. Energy is measured in both frequencies of the BFSK signals. A decision is made by analyzing these energies and locating a specific pattern which repeats itself a sufficient number of times.

摘要： In a half-duplex communication system in which additional delays in the communication channel may cause a message collision between a message and a response, a timer based collision prevention circuit is utilized to prevent the message collision. The collision prevention circuit determines if the message transmitted by a communication device will be repeated. If the message is to be repeated, the collision prevention circuit sets a countdown collision timer to a predetermined period of time shorter than the shortest repetition interval of the repeated message. A response is only sent to the communication device if the collision timer has not expired. If the timer expires, the collision prevention circuit waits for the message to be retransmitted by the source device before sending the response to the communication device.

摘要： A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line telephones, analog wire line fax machines, and computer modems is described. At the start of a telephone call, a data pump interprets the digits dialed, and if a first set of digits are received a control system configures the data pump for processing analog fax data. If a second set of digits are received, the control system configures the data pump for processing analog computer modem data. If a telephone number is received, the control system configures the interface system to pass additional data to a vocoder which encodes any digitized audio information received.
