By utilizing the external memory (or off-chip memory) to temporarily store the incoming data packets when the data rate is extremely high, the disclosed embodiments largely eliminate overloading of the on-chip memory, thereby reducing dropped data packets. | 2013-09-05 |
20130230055 | CONTEXT-SENSITIVE OVERHEAD PROCESSOR - An overhead processor for data transmission in digital communications is disclosed. Incoming data is transmitted along a datapath. If there are two or more groups of incoming data, arriving separately, the initial group(s) of received data can be held in an elastic store until the arrival of additional group(s) of data, and upon the arrival of additional group(s) of data, all received data are combined and transmitted into flip-flop(s). The data is transmitted from said flip-flop(s) to a logic element to determine the new data context of imminent incoming data prior to any additional incoming bytes arriving along the datapath. Therefore, the number of overhead processors required for multi-byte data transmission is reduced, potentially reducing the number of required overhead processors in digital communications to 1. | 2013-09-05 |
