Abstract: One embodiment of the present invention provides a system that supports read-only objects within an object-addressed memory hierarchy. During operation, the system receives a request to access an object, wherein the request includes an object identifier for the object that is used to reference the object within the object-addressed memory hierarchy. In response to this request, the system uses the object identifier to retrieve an object table entry associated with the object. If the request is a write request, the system examines a read-only indicator within the object table entry. If this read-only indicator specifies that the object is a read-only object, the system performs a corrective action to deal with the fact that the write request is directed to a read-only object.

Abstract: One embodiment of the present invention provides a system that reconstructs a high-resolution signal from a set of low-resolution quantized samples. During operation, the system receives a time series containing low-resolution quantized signal values which are sampled from the high-resolution signal. Next, the system performs a spectral analysis on the time series to obtain a frequency series for the low-resolution quantized signal values. The system next selects a subset of frequency terms from the frequency series which have the largest amplitudes. The system then reconstructs the high-resolution signal by performing an inverse spectral analysis on the subset of the frequency terms.

Abstract: One embodiment of the present invention provides a system that implements a pluggable password obscuring mechanism. During operation, the system receives a request to obscure a password to produce an obscured version of the password. If the request specifies a customized technique for obscuring the password, the system loads a dynamic library that performs the customized technique, and then uses the dynamic library to obscure the password. If the request does not specify a customized technique, the system uses a default technique to obscure the password. In this way, the customized technique for obscuring the password can be used without having to modify source code.

Abstract: Conventional tag libraries facilitate web page development by referencing external code from within an HTML page via a mnemonic tag, however such conventional tag libraries typically rely on a manually generated set of supporting code. Such supporting code typically requires a thorough knowledge of the underlying code language, such as Java, C++ and Java Server Pages (JSP). A tag library generator for generating the supporting code corresponding to a tag library mitigates the shortcomings of manually generated support code by parsing a metadata file defining the operations and functions provided by the supporting code. The parser extracts components and renderers corresponding to the supporting code. Each of the components may have corresponding properties, and each of the renderers may have corresponding attributes, which the parser also extracts. The tag library generator receives the parsed items, and processes each of the components with corresponding renderers to generate the applicable support code.

Abstract: One embodiment of the present invention provides a system that facilitates loading classes into non-volatile memory. During the loading process, the system first loads class definitions into volatile memory, wherein the class definitions contain metadata for classes currently being loaded into non-volatile memory, as well as metadata for classes that are already loaded into non-volatile memory. Next, after the class definitions are loaded into volatile memory, the system loads method code for the classes into non-volatile memory. During this process, the system uses the class definitions to resolve linkages in the method code so that the method code is ready for execution in non-volatile memory.

Abstract: One embodiment of the present invention facilitates skewing a bi-directional object layout to provide good cache behavior. During operation, the system receives a request to access an object. This request includes an object identifier and an object offset that specifies the offset of a target field within the object, wherein the object has a bi-directional layout that locates scalar fields at positive offsets and reference fields at negative offsets, so that a reference field can be immediately identified from its object offset. Next, the system determines a skew value for a cache line containing the object, wherein data within the cache line is shifted based upon the skew value, so that reference fields with small negative offsets are likely to be located in the same cache line as scalar fields with small positive offsets. Next, the system uses the skew value in accessing the object.
