Update data to a non-volatile memory may be recorded in at least two interleaving streams such as either into an update block or a scratch pad block depending on a predetermined condition. The scratch pad block is used to buffered update data that are ultimately destined for the update block. In a preferred embodiment, an index of the data stored in the scratch pad block as well that stored in the update block is saved in an unused portion of the scratch pad block every time the scratch pad block is written to.

Update data to a non-volatile memory may be recorded in at least two interleaving streams such as either into an update block or a scratch pad block depending on a predetermined condition. The scratch pad block is used to buffered update data that are ultimately destined for the update block. Synchronization information about the order recording of updates among the streams is saved with at least one of the streams. This will allow the most recently written version of data that may exist on multiple memory blocks to be identified. In one embodiment, the synchronization information is saved in a first block and is a write pointer that points to the next recording location in a second block. In another embodiment, the synchronization information is a time stamp.

In a memory that is programmable page by page and each page having multiple sectors that are once-programmable, even if successive writes are sequential, the data recorded to an update block may be fragmented and non-sequential. Instead of recording update data to an update block, the data is being recorded in at least two interleaving streams. When a full page of data is available, it is recorded to the update block. Otherwise, it is temporarily recorded to the scratch pad block until a full page of data becomes available to be transferred to the update block. Preferably, a pipeline operation allows the recording to the update block to be set up as soon as the host write command indicates a full page could be written. If the actual write data is incomplete due to interruptions, the setup will be canceled and recording is made to the scratch pad block instead.

A data processing system provides development of complex schedule plans under user control by using sorting and grouping processing to interface between a relational database and a scheduler application. The sorting and grouping processing provides for user-interactive editing of data in the database by presentation of groupings of activities developed in accordance with attributes of the activities concurrently with activities which are not included in a group. Editing of the group based on the presentation of other activities allows the user to apply acquired knowledge and understanding of the subtleties and dynamics of the activities and to make business decisions which therefore do not need to be represented in the scheduler application. Changes to data in the database are logged in a notebook or scratch-pad store so that data may be returned to its original or any prior state.

In a memory array having a minimum unit of erase of a block, a scratch pad block is used to store data that is later written to another block. The data may be written to the scratch pad block with a low degree of parallelism and later written to another location with a high degree of parallelism so that it is stored with high density. Data may be temporarily stored in the scratch pad block until it can be more efficiently stored elsewhere. This may be when some other data is received. Unrelated data may be stored in the same page of a scratch pad block.

The present invention is a portable communication device with an interchangeable user input module including two input devices, each disposed on one side of the module, opposite each other, to accommodate multiple functions, space limitations, and size reduction. Two or more features are often combined into one portable communication device to increase functionality. Input devices need to be interchangeable in order to facilitate the multiple features, for example, phone, messaging, personal data assistant, and gaming capabilities, of a portable communication device. The reduction in size of portable communication devices leads to space limitations for input devices. Each side of the interchangeable user input module includes a different input device, for example, QWERTY keyboard, numeric telephone input, touch sensitive panel, scratch pad, or gaming keypad. A user would flip the interchangeable user input module depending on which feature or function was needed.

An authentication apparatus that makes it difficult to perform posing when accessing information is provided. When there is an access request from a mobile phone, an authentication server transmits a program to the mobile phone (S3202). The program is for reading data regarding an individual number (for example, serial number) recorded in a scratch pad of the mobile phone, and transmitting the data to the authentication server. The authentication server that receives the data regarding the serial number transmitted by activation of the program (S3202) compares the serial number with data regarding the identification number of each mobile phone, the data being maintained in the authentication server (S3203). When the serial number matches any of serial numbers maintained therein (S3203: Yes), the authentication server authenticates the access to be valid.

An address containing data to be accessed is determined in response to executing an instruction received at a processor core of a microprocessor. During a scratch-pad mode of operation, it is determined whether a set of cache lines of a data cache is accessible based upon the memory location from which the instruction was retrieved. The address space of the data cache during scratch-pad mode can be isolated from other address spaces.

Software Managed Manycore (SMM) architectures with scratch pad memory for reach core are a promising solution for scaling memory. In these architectures the code and data of the tasks mapped to the cores is explicitly managed by the compiler and often require inter-procedural information and analysis. But, a call graph of the program does not have enough information, and the Global CFG has too much information. Most new techniques informally define and use GCCFG (Global Call Control Flow Graph)—a whole program representation that succinctly captures the control-flow and function call information—to perform inter-procedural analysis. Constructing GCCFGs for several cases in common applications. The present disclosure provides unique graph transformations to formally and correctly construct GCCFGs for optimal compiler management of manycore systems.

A garbage collector that employs the train algorithm to manage a generation in a computer system's dynamically allocated heap maintains for each of the generation's cars a respective remembered set that identifies all locations where references to objects in that car have been found by scanning locations identified by the mutator as having been modified. To avoid some of the expense of remembered-set updating, the collector refrains from attempting to add to a remembered set any reference located in a car that will be collected during the next collection increment. Additionally, if no mutator operation will occur before a collection set of one or more cars will be collected, any reference located outside that collection set but referring to an object within the collection set is not recorded in a remembered set but is recorded instead in a scratch-pad list of entries that identify references to collection-set objects that need to be evacuated.

The present invention provides processing systems, apparatuses, and methods that access a scratch pad on-demand to reduce power consumption. In an embodiment, an instruction fetch unit initiates an instruction fetch. When a scratch pad is enabled, an instruction is retrieved from the scratch pad in parallel with a translation of a virtual address to a physical address. If the physical address is associated with the scratch pad, the retrieved instruction is provided to an execution unit. Otherwise, the scratch pad is disabled to reduce power consumption and the instruction fetch is re-initiated. When the scratch pad is disabled, an instruction is retrieved from another instruction source, such as an instruction cache, in parallel with the translation of the virtual address to the physical address. If the physical address is associated with the scratch pad, the scratch pad is enabled and the instruction fetch is re-initiated.

The invention discloses a method for dynamically allocating on-chip heterogeneous memory resources by utilizing a virtual memory mechanism, comprising the following steps of: analyzing the time and space distribution of data sections (comprising global data, stack data, pile data and constant pool data) with data Cache conflicts caused by high frequency by adopting a time slot analyzing method, then obtaining the time slot conflict diagram of the data Cache by the distribution and carrying out mathematical abstraction for the time slot conflict diagram.
