摘要： A memory operative to provide multi-port functionality includes multiple single-port memory cells forming a first memory array. The first memory array is organized into multiple memory banks, each of the memory banks comprising a corresponding subset of the single-port memory cells. The memory further includes a second memory array including multiple multi-port memory cells and is operative to track status information of data stored in corresponding locations in the first memory array. At least one cache memory is connected with the first memory array and is operative to store data for resolving concurrent read and write access conflicts in the first memory array. The memory includes a controller operative: to receive the status information and to determine a validity of data stored in the first memory array as a function of the status information; to control a manner in which data is stored in the memory for avoiding data overflow in the cache memory; and to resolve concurrent read and write access conflicts in the first memory array during the same memory cycle.

摘要： The invention relates to a method of signal transmission between a host BTS and Remote Radio Unit(s), and the BTS communication system thereof. The transmission channel between the host BTS and the Remote Radio Unit(s) uses wideband transmission links or a network, the method includes the following steps of: performing the transmission over the transmission channel using a Synchronous Digital Hierarchy (SDH)/Optical Transmission Network (OTN), forming a digital wireless signal data stream and an in-band control signaling stream transmitted over the transmission channel into a Generic Framing Procedure (GFP) frame which is further mapped to a STM-N/OTM-n frame, thereby multiplexing the digital wireless signal data stream and the in-band control signaling stream to realize SDH/OTN-based transmission. As a result, the wireless signal can be effectively transmitted between the RRH and the host BTS without specific transmission network, and the management and maintenance operation required by the signal transmission and the networking cost can be reduced.

摘要： Described embodiments provide a first-in, first-out (FIFO) buffer for packet switching in a crossbar switch with a speedup factor of m. The FIFO buffer comprises a first logic module that receives m N-bit data portions from a switch fabric, the m N-bit data portions comprising one or more N-bit data words of one or more data packets. A plurality of one-port memories store the received data portions. Each one-port memory has a width W segmented into S portions of width W/S, where W/S is related to N. A second logic module provides one or more N-bit data words, from the one-port memories, corresponding to the received m N-bit data portions. In a sequence of clock cycles, the data portions are alternately transferred from corresponding segments of the one-port memories in a round-robin fashion, and, for each clock cycle, the second logic module constructs data out read from the one-port memories.
