System and method for efficient channel assignment

A system and method is described for transmitting data from a remote unit to a hub station in order to transmit data across a wide area network, such as the Internet. The remote unit and the hub station have stored frequency tables that include the possible reverse link transmission frequencies. When a remote unit requests a frequency channel, the hub station broadcasts a message that includes the identifier of each remote unit that has requested a reverse link transmission channel. The list of identifiers from the hub station is in a specific order so that it can be stored into each remote unit's frequency table. Once the list of identifiers is stored, the remote unit can find its identifier's position within the frequency table to determine the frequency channel that was assigned by the hub station.

Compiler apparatus and method for optimizing loops in a computer program

A profile-based loop optimizer generates an execution frequency table for each loop that gives more detailed profile data that allows making a more intelligent decision regarding if and how to optimize each loop in the computer program. The execution frequency table contains entries that correlate a number of times a loop is executed each time the loop is entered with a count of the occurrences of each number during the execution of an instrumented instruction stream. The execution frequency table is used to determine whether there is one dominant mode that appears in the profile data, and if so, optimizes the loop according to the dominant mode. The optimizer may perform optimizations by peeling a loop, by unrolling a loop, and by performing both peeling and unrolling on a loop according to the profile data in the execution frequency table for the loop. In this manner the execution time of the resulting code is minimized according to the detailed profile data in the execution frequency tables, resulting in a computer program with loops that are more fully optimized.

The echo signals are down-converted by mixing them with the transmitted signal, to obtain received Intermediate Frequency (IF) signal, which is then sampled both in phase (I-channel) and in quadrature phase (Q-channel). The received IF signal passes a Fourier transform, to obtain power spectral components that belong to a relevant frequency domain, associated with an echo signal reflected from a real target, along with corresponding power spectral components that belong to an irrelevant, opposite frequency domain. The noise distribution and level in the relevant frequency domain is calculated by estimating the noise level in the irrelevant frequency domain and targets represented by a set of consequent relevant frequencies are detected by comparing the power spectral component at each relevant frequency to the calculated noise level and identifying power spectral components with likelihood, which is above a predetermined threshold.

System and method for dynamic clock generation

An application specific integrated circuit (ASIC) has a clock controller that dynamically selects an appropriate clock frequency for a resource. The ASIC includes a central processing unit (CPU), on-chip memory, a memory controller controlling external memory devices, a system bus, and various peripheral controllers. Devices that can be accessed by other devices, such as the on-chip memory, the memory controller, and the system bus are “resources.” The devices that access the resources are “controllers.” The ASIC generates a master clock and the clock controller derives clocks for driving the resources and controllers from the master clock. A multiplexer (MUX) in the clock controller selects the clock that is passed to a resource. Each controller has a request line to the clock controller for signaling when the controller is accessing a resource. The clock controller has a programmable register for each controller holding a value representing the bandwidth utilization of the controller and an adder and a frequency table. The adder sums the contents of the bandwidth registers of the controllers that are accessing a resource. The sum is an index to an entry in a frequency table. The value held in the frequency table is applied to the selection inputs of the MUX to select the clock for the resource. If no controllers are requesting access to the memory controller, the clock controller shuts down the memory clock. Accordingly, the clock frequency of the resource is determined by the bandwidth utilization of the controllers requesting access to the resource.
