A mobile communication device () loads an application bundle (), which includes a software application () and an indication of a time limited license (). To enforce the time limited license, the mobile communication device, upon attempting to invoke the application code (), obtains a secure time reading (). It is contemplated that a secure time server () may be used to facilitate license enforcement. Once the secure time reading is obtained, the mobile communication device compares the time with the license period, and executes the code only if the time reading is within the license period.

A signed application descriptor file ( ) is used instead of X.509 certificates to authenticate a portable application code, such as a JAVA archive (JAR) file. The signed ADF includes an application descriptor file ( ), file hash ( ) of the JAR file ( ), a developer descriptor file ( ), signed time stamp ( ), and a developer's certificate ( ). A network client device ( ) includes limited computing resources ( ) and a virtual machine environment for executing the portable code ( ). Furthermore the client device contains a set of cryptographic, digital keys for authenticating parts of the signed ADF, which are further used to authenticate the JAR file.

A computer system (100) comprises a processor (110), a memory (300), an interface (101) and peripheral devices (120-1, 120-2, 120-3). The interface has a pointer generator (160), a port (150), a decoder (170), and a parameter register (180). The port (150) transmits data words D(k) (380-k) from the memory (300) to the peripheral devices (120-1, 120-2, 120-3) or vice versa. Communication parameters are stored as parameter sets {P.sub.m } in parameter fields (185-m) of the parameter register (180). The decoder (170) selects a parameter set {P.sub.i } using from control words C(k) stored in the memory (300). Data queues can simultaneously be transmitted to two or more peripheral devices (120-1, 120-2, 120-3).

In radio processing control (11), a plurality of architectural layers (270, 290, 390) separate at least one of a plurality of tasks (272) from another task (292). For communicating among the tasks within (274, 276, 278) or across (229, 239) the layers, a buffer (300) for each of the tasks is provided by a communication resource (602). A messaging protocol for passing information from the tasks is defined to be a predefined information packet having a header (700) preceding any optional data. A flag portion (701) of the header designates the information as intralayer or interlayer. If the information is interlayer (229, 239), an identifier portion (703, 704) of the header identifies the source (272) of the information and an operation portion (702) identifies an operation code.

A tone generator for producing a plurality of output tone waveforms for a plurality of frequencies, includes an encoder for selectively generating a first waveform that has a first number of states and second waveform that has a second number of states which are less than the first number of states. A control circuit is connected to the encoder and selects the second waveform for higher frequency output tones and the first waveform for lower frequency output tones. The control circuit provides a control clock signal to the encoder for determining the frequency of the output tones. A low pass filter is connected to the encoder for filtering the output tones. The encoder includes a plurality of flip flips having outputs connected to a summer by gates that are actuated by the control circuit.
