摘要： The disclosure is applied to a generic microprocessor architecture with a set (e.g., one or more) of controlling elements (e.g., MPEs) and a set of groups of sub-processing elements (e.g., SPEs). Under this arrangement, MPEs and SPEs are organized in a way that a smaller number MPEs control the behavior of a group of SPEs using program code embodied as a set of virtualized control threads. The arrangement also enables MPEs delegate functionality to one or more groups of SPEs such that those group(s) of SPEs will act as pseudo MPEs. The pseudo MPEs will utilize pseudo virtualized control threads to control the behavior of other groups of SPEs. In a typical embodiment, the apparatus includes a MCP coupled to a power supply coupled with cores to provide a supply voltage to each core (or core group) and controlling-digital elements and multiple instances of sub-processing elements.
摘要翻译：本公开应用于具有一组（例如，一个或多个）控制元件（例如，MPE）和一组子处理元件（例如，SPE）的通用微处理器架构。在这种安排下，MPEs和SPE的组织方式是使用较少数量的MPE使用体现为一组虚拟控制线程的程序代码控制一组SPE的行为。该安排还使MPEs能够将功能委托给一个或多个SPE组，使得这些SPE组将充当伪MPE。伪MPE将利用伪虚拟化控制线程来控制其他组的SPE的行为。在典型的实施例中，该装置包括耦合到与核耦合的电源的MCP以向每个核（或核心组）提供电源电压以及控制数字元件和子处理元件的多个实例。

摘要： This invention describes an apparatus, computer architecture, memory structure, memory control, and cache memory operation method for multi-core processor. A logic core bypasses immediate cache memory units with low yield or deadly performance. The core mounts (multiple) cache unit(s) that might already be in use by other logic cores. Selected cache memory units serve multiple logic cores with the same contents. The shared cache memory unit(s) serves all the mounting cores with cache search, hit, miss, and write back functions. The method recovers a logic core whose cache memory block is not operational by sharing cache memory blocks which might already engage other logic cores. The method is used to improve reliability and performance of the remaining system.

摘要： Specifically, under the present invention an available on-chip memory is coupled to another logic core or memory (e.g., cache) unit using a set of cache managers. Specifically, each cache manager is coupled to the input and output of a cache memory unit. This allows the assigned memory to become an extension of the same level cache, next level cache memory, or memory buffer. This also allows the recovery of a memory block whose logic core is not operational, and is used to improve cache memory performance of the system. It should be understood in advance the teachings herein are typically applied to a Multi-Core Processor (MCP), although this need not be the case.
摘要翻译：具体地说，在本发明中，使用一组缓存管理器将可用的片上存储器耦合到另一个逻辑核心或存储器（例如，高速缓存）单元。具体地，每个高速缓存管理器耦合到高速缓冲存储器单元的输入和输出。这允许分配的内存成为同一级缓存，下一级高速缓存或内存缓冲区的扩展。这也允许恢复其逻辑内核不可操作的内存块，并用于提高系统的高速缓存内存性能。应该预先理解这里的教导通常应用于多核处理器（MCP），尽管不一定是这种情况。

摘要： This disclosure describes an apparatus, computer architecture, method, operating system, compiler, and application program products for MPEs as well as virtualization across physical boundaries that define physical partitions in a symmetric MCP. Among other things, the disclosure is applied to a generic microprocessor architecture with a set (e.g., one or more) of controlling/main processing elements (e.g., MPEs) and a set of groups of sub-processing elements (e.g., SPEs). The arrangement also enables MPEs to delegate functionality to one or more groups of SPEs such that those group(s) of SPEs may act as pseudo MPEs. Such delegation may occur across the physical boundaries. Regardless, the pseudo MPEs may utilize pseudo virtualized control threads to control the behavior of other groups of SPEs also across physical boundaries.

摘要： Specifically, under the present invention, a cache memory unit can be designated as a pseudo cache memory unit for another cache memory unit within a common hierarchal level. For example, in case of cache miss at cache memory unit “X” on cache level L2 of a hierarchy, a request is sent to a cache memory unit on cache level L3 (external), as well as one or more other cache memory units on cache level L2. The L2 level cache memory units return search results as a hit or a miss. They typically do not search L3 nor write back with the L3 result even (e.g., if it the result is a miss). To this extent, only the immediate origin of the request is written back with L3 results, if all L2s miss. As such, the other L2 level cache memory units serve the original L2 cache memory unit as pseudo caches
摘要翻译：具体地说，在本发明中，高速缓冲存储器单元可以被指定为公共层级内的另一高速缓冲存储器单元的伪高速缓冲存储器单元。例如，在层次结构的高速缓存级L2上的高速缓存存储器单元“X”处的高速缓存未命中的情况下，将请求发送到高速缓存级L3（外部）上的高速缓冲存储器单元以及一个或多个其他高速缓冲存储器单元在缓存级L2上。 L2级缓存单元返回搜索结果作为命中或未命中。它们通常不会搜索L3，也不会用L3结果写回（即使结果是错过）。在这个程度上，如果所有的L2都错过，只有请求的直接起始点才会用L3结果写回来。这样，其他L2级高速缓冲存储器单元用作原始高速缓存存储器单元作为伪高速缓存
