Abstract: A communication antenna and radiation unit thereof with tapered clearance slots for transceiving radiation signals disposed at four corners of the radiation unit. The slots form groups and are arranged and fed by two feeding units. A middle portion of the radiation unit is a flat central platform. Peripheries of the radiation unit are turned up to form folded edges. The communication antenna includes a reflecting plate and a radiation unit operating at a low frequency. The central platform has a high-frequency radiation element. The radiation unit has a small aperture and is lightweight, so the antenna size is reduced, and a radiation performance indicator can be ensured. The radiation unit is applied to a multi-frequency antenna, has little effect on a high-frequency oscillator, and is especially suitable for a multi-frequency base station antenna with a low-frequency unit and a high-frequency unit forming an array in a nested manner.

Abstract: A method and system for trace generation using memory index hashing. A method may include generating an extended trace representative of M threads of instruction execution from a trace representative of N threads of instruction execution, where N and M are integers, N?1 and M>N, and where each of the N threads of the trace includes memory references to respective memory addresses. Generating the extended trace from the trace may include replicating the N threads to generate the M threads, assigning a respective identifier to each of the M threads, and for a given one of the M threads, hashing a first portion of each of the respective addresses dependent upon the respective identifier of the given thread, where the first portion of each of the respective addresses corresponds to at least part of an index of a memory structure shared by at least two of the M threads.

Abstract: An apparatus and method for mapping memory addresses to reduce or avoid conflicting memory accesses in memory systems such as cache memories is described in connection with a multithreaded multiprocessor chip. A CMT processor reduces the probability of hot-spots in cache operations by hashing certain bits of a physical cache address to form a hashed cache address. By using exclusive OR functionality to hash the index bits, an efficient address transformation is achieved for indexing into an L2 cache memory.
