摘要： Embodiments of a processor architecture utilizing multi-bank implementation of physical register mapping table are provided. A register renaming system to correlate architectural registers to physical registers includes a physical register mapping table and a renaming logic. The physical register mapping table has a plurality of entries each indicative of a state of a respective physical register. The mapping table has a plurality of non-overlapping sections each of which having respective entries of the mapping table. The renaming logic is coupled to search a number of the sections of the mapping table in parallel to identify entries that indicate the respective physical registers have a first state. The renaming logic selectively correlates each of a plurality of architectural registers to a respective physical register identified as being in the first state. Methods of utilizing the multi-bank implementation of physical register mapping table are also provided.

摘要： In a network-on-chip (NoC) system, multiple data messages may be transferred among modules of the system. Power consumption due to the transfer of the messages may affect a cost and overall performance of the system. A described technique provides a way to reduce a volume of data transferred in the NoC system by exploiting redundancy of data messages. Thus, if a data message to be sent from a source in the NoC includes so-called “zero” bytes that are bytes including only bits set to “0,” such zero bytes may not be transmitted in the NoC. Information on whether each byte of the data message is a zero byte may be recorded in a storage such as a data structure. This information, together with non-zero bytes of the data message, may form a compressed version of the data message. The information may then be used to uncompress the compressed data message at a destination.
摘要翻译：在片上网络（NoC）系统中，可以在系统的模块之间传送多个数据消息。由于消息传送引起的功耗可能会影响系统的成本和整体性能。所描述的技术提供了一种通过利用数据消息的冗余来减少在NoC系统中传送的数据量的方法。因此，如果要从NoC中的源发送的数据消息包括仅包括设置为“0”的字节的所谓的“零”字节，那么这种零字节可能不会在NoC中发送。关于数据消息的每个字节是否为零字节的信息可以被记录在诸如数据结构的存储器中。该信息与数据消息的非零字节可以形成数据消息的压缩版本。然后可以使用该信息来在目的地解压缩压缩数据消息。

摘要： Embodiments of a processor architecture efficiently implement shadow registers in hardware. A register system in a processor includes a set of physical data registers coupled to register renaming logic. The register renaming logic stores data in and retrieves data from the set of physical registers when the processor is in a first processor state. The register renaming logic identifies ones of the set of physical registers that have a first operational state as a first group of registers and identifies the remaining ones of the set of physical registers as a second group of registers in response to an indication that the processor is to enter a second processor state from the first processor state. The register renaming logic stores data in and retrieves data from the second group of registers but not the first group of registers when the processor is in the second processor state.
