    摘要： According to the invention, a processing core is disclosed. The processing core includes one or more processing pipelines and a number of register flies. The processing pipelines having a total of N-number of processing paths, where each of the processing paths processes instructions on M-bit data words. Each of the number of register files has Q-number of registers that are each M-bits wide. The Q-number of registers within each of the plurality of register files are either private or global registers. When a value is written to one of said Q-number of said registers, which is a global register within one of said number of register files, the value is propagated to a corresponding global register in the other of the number of register files. When a value is written to one of said Q-number of the registers, which is a private register within one of said number of register files, the value is not propagated to a corresponding register in the other of said number of register files.

    摘要： A microprocessor with reduced context switching overhead and a corresponding method is disclosed. The microprocessor comprises a working register file that comprises dirty bit registers and working registers. The working registers including one or more corresponding working registers for each of the dirty bit registers. The microprocessor also comprises a decoder unit that is configured to decode an instruction that has a dirty bit register field specifying a selected dirty bit register of the dirty bit registers. The decoder unit is configured to generate decode signals in response. Furthermore, the working register file is configured to cause the selected dirty bit register to store a new dirty bit in response to the decode signals. The new dirty bit indicates that each operand stored by the one or more corresponding working registers is inactive and no longer needs to be saved to memory if a new context switch occurs.

    摘要： An integrated processor/memory device comprising a main memory, a CPU, and a full width cache. The main memory comprises main memory banks. Each of the main memory banks stores rows of words. The rows are a predetermined number of words wide. The cache comprises cache banks. Each of the cache banks stores one or more cache lines of words. Each of the cache lines has a corresponding row in the corresponding main memory bank. The cache lines are the predetermined number of words wide. When the CPU issues an address in the address space of the corresponding main memory bank, the cache bank determines from the address and the tags of the cache lines whether a cache bank hit or a cache miss has occurred in the cache bank. When a cache bank miss occurs, the cache bank replaces a victim cache line of the cache lines with a new cache line that comprises the corresponding row of the corresponding memory bank specified by the issued address.

    摘要： A method and apparatus for delivering a device driver to an operating system without user intervention. One or more operating systems (e.g., different operating system programs, different versions of one operating system) execute on a computer platform. During booting of an operating system a device is identified for which a driver is needed. The driver is requested from a service processor of the platform, which includes memory or storage for storing multiple device drivers (or multiple versions of one driver, for different operating systems). The driver is retrieved from the service processor's storage and delivered to the operating system.

    摘要： A plurality of processors on a chip is operated in lockstep. A crossbar switch on the chip couples and decouples the plurality of processors to a plurality of banks in a level-two (L2) cache. As data is stored in a first bank of the L2 cache, the old data at that location is passed through the crossbar switch to a second bank of the L2 cache that is functioning as a first-in-first-out memory (FIFO). Thus, new data is cached at a location in the first bank of the level-two cache, i.e., stored, and old data, from that location, is logged in the second bank of the level-two cache. The logged data in the second bank is used to restore the first bank to a known prior state when necessary.

    摘要翻译： 芯片上的多个处理器在锁定状态下运行。 芯片上的交叉开关将多个处理器耦合并分离到二级（L2）高速缓存中的多个存储体。 当数据存储在L 2高速缓存的第一组中时，该位置处的旧数据通过交叉开关传递到作为先入先出存储器（FIFO）的L 2高速缓存的第二组 ）。 因此，新数据被缓存在二级高速缓存的第一组中的位置，即存储，并且来自该位置的旧数据被记录在二级高速缓存的第二组中。 当需要时，第二组中记录的数据用于将第一组恢复到已知的先前状态。
