A method and apparatus for performing unit testing of software modules uses a novel directed automated random testing approach that advantageously combines automated extraction of the interface of a program with its external environment using static source code parsing; automatic generation of a test driver for this interface that advantageously performs random testing to simulate the most general environment the program can operate in; and dynamic analysis of how the program behaves under random testing and automatic generation of new test inputs to direct systematically the execution along alternative program paths. Together, these techniques constitute a directed automated random testing approach (DART). With DART, testing can be performed completely automatically on any program that compiles without the need to write any test driver or harness code. During testing, DART detects standard errors such as program crashes, assertion violations, and non-termination conditions.

A method and apparatus for selecting radio stations for reception based on a preferred program content. A list of radio station identifiers is stored in a memory and organized according to program content specifiers. When a presently received signal fades, the memory is searched for an alternate radio station with similar program content. If none is available, a prioritized list of alternative program content preferences is accessed and used to index other preferred radio stations for searching. In one embodiment, radio station geographic location information is stored in the memory, and the searching operation considers both program content preference and geographic proximity. The memory can be manually programmed, pre-programmed, updated by subscription, or programmed over-the-air by radio transmission. In one embodiment, a global positioning system receiver is employed to provide instantaneous radio location information.

A program modification database and method for identifying a candidate entry within the correction database for a particular executable program are disclosed. The program modification database provides a general depository of program changes, referred to herein as substitute program segments, and a set of executable program entries containing program matching criteria and corresponding program changes. The program modification database includes an index. Each entry in the index includes a piece of identifying information for a referenced, corresponding executable program entry. The program modification database architecture is applicable to any type of program segment information for modifying either instruction code or data values within a program. The types of information, within a program matching criteria, taken from an executable program file used to identify a corresponding executable program entry within the program modification database are selectable on an individual basis from an extensible set of executable program information types.

Multi-processor computer systems with multiple levels of cache memories are slowed down in trying to process software locks for common functions. This invention obviates the problem for the vast majority of transactions by providing an alternate procedure for handling so-called communal locks differently from ordinary software locks. The alternative procedure is not used for ordinary (non communal software lock) data and instruction transfers. The function of the CSWL (Communal SoftWare Lock) is actually accomplished at a specific cache to which an individual CSWL is mapped to, rather than sending the lock to the requesting process, which also enhances efficiency.

According to the invention, a method for suggesting alternative content for a video service in a content distribution system is disclosed. In one step, it is detected when a user stops viewing a program associated with a content provider. Alternative programs associated with the content provider are determined without considering content from other providers. Those alternative programs are presented to the user.

In technology for enabling the replacement of part of an operating program of a controller by a modified program on a nonvolatile memory, the present invention prevents tampering and leak of storage information within the nonvolatile memory and the controller. At power-on reset, an encrypted alternative program, if present, is transferred from a nonvolatile memory to a volatile memory, and decrypted when actually executed. A long wait is not required until data processing by a data processor is enabled after the exit from the reset processing. Since the alternative program once decrypted is held in the volatile memory so as to be reusable, it does not need to be decrypted each time it is executed. Since the alternative program is encrypted, even if the nonvolatile memory is physically separated from the controller to illegally dump the alternative program, it is difficult to analyze the data.

A method of embedding information in a computer program code, including a plurality of program statements. The method comprises: inserting a conditional program statement in the computer program code, the conditional program statement including a condition and a plurality of alternative program statements, the conditional program statement being adapted to cause a data processing system to evaluate said condition and, responsive to a result of said evaluating step, to selectively execute one of said plurality of alternative program statements; wherein said condition is indicative of at least a part of said information; and wherein the plurality of alternative program statements are adapted to cause the computer program code to produce the same program output irrespective of which of said alternative program statements is executed.

Among the techniques for realizing replacement of part of the controller's working program by modifying the program on the nonvolatile memory, the present invention prevents tampering and leakage of stored information in the nonvolatile memory and the controller. At power-on reset, if an encrypted alternative program exists, it is transferred from the non-volatile memory to the volatile memory and decrypted when it is actually executed. There is no need to wait for a long time until the data processing of the data processor is allowed after exiting from the reset processing. Since the substitute program once decrypted is held in volatile memory for re-use, it does not need to be decrypted each time it is executed. Since the substitute program is encrypted, it is difficult to analyze the data even if the nonvolatile memory is physically separated from the controller to illegally dump the substitute program.

The invention also provides an intelligent upgrading system for the program. The efficiency and the reliability of the upgrading are greatly improved.
