摘要： A removable card for use with a mobile wireless communication device has a processor and a non-volatile memory, connected to the processor. The memory has programming code stored configured to be executed by the processor and is operable in one of two modes. In a first mode the card is connected to the device with the card storing information received wirelessly by the device from the Internet. In a second mode the card is connected to a network portal device, which is connected to the Internet, with the card storing information received through the network portal device from the Internet. In another embodiment, the removable card has electrical connections for connecting to a mobile wireless communicating device for use by a user to connect to the Internet. The memory has two portions: a first portion and a second portion with the partitioning being alterable. The processor restricts access to the first portion by the user, while grants access to the second portion to the user. Finally, the present invention relates to a mobile wireless communication device.

摘要： All Pointer-based accesses require first that the value contained in a pointer register (200a, 200b, 200c, 200d) to be read and then that value be used as an address to the appropriate region in random access memory (RAM) (104). As implemented today, this requires two memory read access cycles, each of which takes at least one clock cycle and therefore this implementation does not allow single cycle operation. In accordance with an embodiment of the invention, when an access is performed to pointer memory (103a, 103b, 103c, 103d) to read the contents of a pointer, it is the shadow memory that is actually read and that returns the pointer value. Since the shadow memory is made up of pointer registers (200a, 200b, 200c, 200d), a read access involves mutliplexing out of appropriate data for the pointer address from these pointer registers (200a, 200b, 200c, 200d) to form a target pointer address. This target pointer address is then used as an address to access RAM (104) without the overhead of a clock, since the register access is purely combinatorial and does not require clock-phase related timing as does access to the RAM (104).

摘要： Typically, for processing systems it must be guaranteed that all interrupted program stream parameters are restored before the execution of the first program stream resumes. If during this transfer an interrupt occurs, then all data may not be stored or restored. If the error free storage of the program register contents and other critical first program stream data does not occur, the processor (180) has no way of knowing whether the first program stream data restored to the registers has become corrupt or not. Thus, a novel register architecture (120, 121, 122, 123, 124, 125) is provided that facilitate processing of interrupting program streams without storing and restoring interrupted program stream critical data.

摘要： A processing system with extended addressing capabilities includes a control bit that controls the number of address bytes that are stored onto a program stack. If the control bit is set to a first state, the address is pushed onto the program stack in the same manner as that used for shorter-address legacy devices. If the control bit is set to a second state, the address is pushed onto the program stack using the number of bytes required to contain a longer extended address. This same control bit controls the number of bytes that are popped off the stack upon return from an interrupt subroutine. The state of the control bit is controlled by one or more program instructions, thereby allowing it to assume each state dynamically. This dynamic control of the number of bytes pushed and popped to and from the stack allows for an optimization of stack utilization, and thereby further compatibility with legacy devices and applications.

摘要： An integrated circuit device has a processing unit, a memory management unit, and a memory. The memory management unit is interposed between the memory and the processing unit for controlling access to the memory by the processing unit in one of three modes. In a first mode, called the system mode, the processing unit can access a system program stored in the memory for controlling the resources of the integrated circuit device. In a second mode, called the kernel mode, the processing unit can access an operating system program stored in the memory for controlling the of the integrated circuit device, limited by the system program. Finally in a third mode, called the user mode, the processing unit can access an application program stored in the memory for controlling the resources of the integrated circuit device, limited by the operating system program. In another aspect of the invention, when the processing unit accesses either the operating system program or the application program (herein: “non-system program”), the execution of the non-system program can cause a system interrupt causing program execution to revert to the system mode, but to a specified entry address of the system program, wherein after processing the system interrupt, operation returns to the non-system program in either the kernel mode or the user mode.
