Processing Analysis The SR signal processing functions are as follows: † FEC channel encoding and decoding: this can include a CRC, convolutional and turbo encoding/decoding; † Interleaving/de-interleaving: ... and 3G) terminal, one can consider the ‘‘ Velcro’’ solution consisting of assembling two single mode terminals in the same case, with minimal hooks needed to allow inter-system monitoring. This ... chain of transfers autonomously. Such DMA engines are ideal for transferring data in and out of LCC units with minimal DSP intervention. This reduces or even eliminates DSP overhead in performing...

... The values in the table have been determined for a solution using turbo decoding and they do not include chip-le vel decoding and symbol level combining that further increase the processing needs. The ... architectures, including the operating system principles, are strikingly similar, although the mobile computing systems tend to rely more on hardware accelerators. As the performance expectations of mobile devices ... anything in between 1-2 cycle instruction set extensions and peripheral devices executing thousands of cycles can result in grossly inefficient software. If the interrupt latency in the operating...
