A method for storing and transmitting data by using a vehicle key includes: the vehicle key receives and stores first data from an intelligent vehicle, where the first data is non-real-time processing data from the intelligent vehicle; and the vehicle key sends the first data to cloud. In this way, while data transmission costs of the intelligent vehicle are reduced, user experience of the intelligent vehicle is improved.

A method, computer system, and a computer program product for improving debugging speed by rearranging debugging priority functions. In one embodiment, runtime input may be received about a program to be debugged. Feedback information is obtained about at least one similar program previously debugged. The compiling time information and runtime information are analyzed to determine a status of functions including one or more focused functions that will be used frequently and one or more unreachable functions that may never will be executed. A priority list of debugging functions is generated based on the feedback information, the runtime input and a function status. A plurality of debugging information are rearranged and parsed on the priority list prior to said program being debugged based on said debugging information.

Debugging by predict accessing information

A computer-implemented method, system and computer program product for reducing register pressure. Loops of a computer program with a number of live variables that exceeds a threshold number, such as the number of available registers with capacity to store data, are identified. Such identified loops may be the to be subject to high register pressure. Upon identifying such loops in the computer program, chains within each identified loop are identified, where each chain includes load and store instructions from the same induction address and where the variable offsets of the load and store instructions are loop invariants. The address expressions for the load and store instructions in the identified chains may then be modified or changed to reuse common variable offsets using an analysis and transformation process. By reusing common variable offsets, there are less variable offsets that need to be stored in the registers thereby mitigating register pressure.

Reducing register pressure

A method, computer program product, and computer system are provided. An enhanced compiler identifies instructions for execution among them, instructions directed to an inner computation unit of a CPU core. In response to identifying instructions directed to the inner computation unit, locating in a system call table a system call to indicate a begin of an executable code block of instructions that are directed to the inner computation unit of the CPU core. The enhanced compiler searches the system hardware registry for the parameter corresponding to the inner computation unit of the CPU core. The system call is inserted as an interrupt instruction in the compiler output at the begin of the executable code block of instructions that are directed to the inner computation unit of the CPU core. The enhanced compiler executable code output is saved for later selection by a scheduler of an operating system.

Provided are embodiments for a method of performing register pressure targeted function splitting. The method can include determining a candidate region of a function, the candidate region comprising variables, and determining a number of available registers in a computing system for allocating the variables of the function. The method can also include grouping the variables in the candidate region into first variables and second variables based at least in part on the number of available registers, and splitting the candidate region of the function into split functions based at least in part on the grouping of the variables. Also provided are embodiments for a computer program product and a system for performing register pressure targeted function splitting.

Provided are techniques for using relocatable debugging information entries to save compile time when there are changes to source code. While compiling source code, for an unchanged function, a copy is made of a relocatable debugging information entries table and of a relocation information table. In addition, for a changed function, a new relocatable debugging information entries table and a new relocation information table are generated. The copy of the relocatable debugging information entries table and the new relocatable debugging information entries table are merged. The copy of the relocation information table and the new relocation information table are merged. The relocatable debugging information entries in the merged relocatable debugging information entries table are resolved according to information in the merged relocation information table to generate relocated Debugging with Attributed Record Formats information, which is stored in an object file that corresponds to the source code.

Embodiments of the present disclosure relate to methods, systems, and computer program products for monitoring a state of an application. A target object that is to be monitored in an application may be determined in response to receiving a monitoring configuration. A position of the target object in source codes of the application may be identified. A state of the target object may be monitored in response to the application being traced to a location corresponding to the position.

A method of fabricating a spiral inductor includes providing a substrate having a top surface and a bottom surface, forming a plurality of through holes aligned in a vertical plane and spaced apart from each other, forming a metal interconnect structure having at least one top metal layer on the top surface of the substrate, the metal interconnect structure configured to connect to a top portion of the through holes, and forming a redistribution layer having at least a bottom layer on the bottom surface of the substrate. The redistribution layer is configured to connect to a bottom portion of the through holes to form a spiral structure.

Method of manufacturing a vertical inductor

A spiral inductor formed in a vertical plane relative to a planar surface of a substrate includes a plurality of through holes disposed in the vertical plane and spaced apart from each other, a metal interconnect structure on the top surface, and a redistribution layer on the bottom surface and having at least one bottom metal layer. The metal interconnect structure and the redistribution layer are connected to each other through the plurality of through holes to form the vertical spiral inductor. The thus formed vertical spiral inductor has a significantly reduced surface area comparing with lateral spiral inductors.
