摘要： Ensuring real-time performance of multitask control and improving the processing efficiency of a system provided with a processor processing while switching between a plurality of tasks. The system includes an execution unit executing instructions on individual tasks while switching from one task to another, a distinguishing unit executing an instruction determined to be a predetermined instruction. The system further includes a determination unit set so that on condition that the instruction to be executed is the predetermined instruction, it determines whether to allow the execution unit to execute the predetermined instruction or to perform a task switching process without executing the predetermined instruction based on a predetermined condition.

摘要： An apparatus includes a range determination module that determines a search range of TCAM content values and a search criteria module that creates a TCAM search value from a search range by combining common higher order bits with don't care lower order bits that change within the search range. A match module searches the TCAM using the search value to determine a match count. A division module creates upper and lower sub-ranges by creating upper and lower midpoint content values within the search range. The upper sub-range is between an upper content value and the upper midpoint content value and the lower sub-range is between the lower midpoint content value and a lower content value. The upper midpoint content value includes changing a most significant don't care bit to a 1 and remaining don't care bits to 0. The lower midpoint content value includes changing a most significant don't care bit to 0 and remaining don't care bits to 1.

摘要： A method for programmably controlling an exception includes performing, by a processor, a step of executing a control specification instruction for exception control specification that indicates whether an exception is enabled or not and setting a control specification value for the exception in a register and a step of executing a control execution instruction for exception control execution that indicates whether the exception is to be raised or not, determining whether the control specification value set in the register is a value for enabling the exception, and, when the control specification value is the value for enabling the exception, raising the exception. The method further includes performing a step of not raising the exception when the control specification value set in the register is not the value for enabling the exception.

摘要： When short MPEG2 data transfer streams, such as those used for commercials, are sequentially distributed within a short period of time, a decoder method synchronizes the transfer and prevents accumulation of data in a buffer and data losses. The synchronization method extracts sync data originating at the transmission source from a received data stream; acquires sync data for a decoder based on a reference clock; compares the sync data originating at the transmission source with the sync data for the decoder in order to sequentially obtain control values, sequentially updates the frequency of the reference clock for transfer synchronization for the received data stream; determines whether or not a data stream that differs from the received data stream has been received; and employs, when a different data stream has been received, the reference clock obtained when the received data stream has been received, to initiate transfer synchronization for the different data stream.

摘要： A control unit of a least recently used (LRU) mechanism for a ternary content addressable memory (TCAM) stores counts indicating a time sequence with resources in entries of the TCAM. The control unit receives an access request with a mask defining related resources. The TCAM is searched to find partial matches based on the mask. The control unit increases the counts for entries corresponding to partial matches, preserving an order of the counts. If the control unit also finds an exact match, its count is updated to be greater than the other increased counts. After each access request, the control unit searches the TCAM to find the entry having the lowest count, and writes the resource of that entry to an LRU register. In this manner, the system software can instantly identify the LRU entry by reading the value in the LRU register.
摘要翻译：用于三元内容可寻址存储器（TCAM）的最近最少使用（LRU）机制的控制单元存储指示具有TCAM条目中的资源的时间序列的计数。控制单元接收具有定义相关资源的掩码的访问请求。搜索TCAM以找到基于掩码的部分匹配。控制单元增加对应于部分匹配的条目的计数，保持计数的顺序。如果控制单元也找到精确匹配，则其计数更新为大于其他增加的计数。在每个访问请求之后，控制单元搜索TCAM以找到具有最低计数的条目，并将该条目的资源写入LRU寄存器。以这种方式，系统软件可以通过读取LRU寄存器中的值来立即识别LRU条目。
