    摘要： A new method and apparatus are used to check for segment limit violations during memory access. When a segment descriptor is retrieved during the initialization of a segment, the segment limit from the segment descriptor is used to create five limits. The five limits are the last possible address within the segment for each size of memory access. During a subsequent memory access, the limit corresponding to the segment being accessed and the length of memory access is selected. The selected limit is compared against the address of the memory access to determine if a limit violation has occurred. If a limit violation has occurred, a flag is set that, when read, will cause an exception.

    摘要： A temperature difference between a first thermal sensor and a second thermal sensor on a first die is determined. The temperature difference is transmitted from the first die to a circuit on a second die. A temperature from a thermal sensor on the second die is determined. The temperature difference and the temperature from the thermal sensor are utilized on the second die to modify operational characteristics of one or more circuits on the second die.

    摘要： An address translator and a method for translating a linear address into a physical address for memory management in a computer is described herein. Different memory sizes, and different page sizes can be selected. The address translator can translate from a standard 32-bit linear address for compatibility with previous 32-bit architectures, and can also translate to a physical memory size with a larger physical address than linear address; i.e., greater than 32 bits (e.g. 36 bits and up), with no increase in access time. The address translator translates a linear address that includes an offset and a plurality of fields used to select entries in a plurality of tables. The format of the linear address into fields is dependent upon the selected memory size and the selected page size. For a large memory size, the tables include a directory pointer table that includes a group of directory pointers, a plurality of page table directories each of which includes a group of page directory entries, and a plurality of page tables each of which includes a group of page table entries. The size of the entries in the tables is dependent upon the selected memory size. The contents of the tables are stored in memory, and furthermore the pointer table is stored in both main memory and in dedicated pointer table registers.

    摘要： An integrated circuit such as a SoC may indicate the critical battery status without powering-on a substantial portion including the host processing cores. The SoC may include a microcontroller, which may cause the critical battery status data to be stored in a static memory and the display unit may retrieve such data from the static memory to display a visual symbol on the screen. The other portions of the SoC such as the dynamic memory, system agent, media processors, and memory controller hubs may be powered-down while the critical battery status is displayed in the visual form on the screen.

    摘要： A method and apparatus for compensating for current-change induced voltage changes is disclosed. In one embodiment, a digital throttle unit coupled to an instruction pipeline may generate a compensating current signal, which may then cause a dummy load to consume a compensating current. In another embodiment, a counter responsive to changes in clock frequency may generate a ramp current signal, which may then cause a dummy load to consume a current corresponding to the ramp current signal.

    摘要： The present invention provides a mechanism for supporting high bandwidth instruction fetching in a multi-threaded processor. A multi-threaded processor includes an instruction cache (I-cache) and a temporary instruction cache (TIC). In response to an instruction pointer (IP) of a first thread hitting in the I-cache, a first block of instructions for the thread is provided to an instruction buffer and a second block of instructions for the thread are provided to the TIC. On a subsequent clock interval, the second block of instructions is provided to the instruction buffer, and first and second blocks of instructions from a second thread are loaded into a second instruction buffer and the TIC, respectively.
