When the BE devices were being defined there were many discussions on what feature would be beneficial in a high-speed, low-latency device. It was determined that some relatively simple functions are very common for systems and take up very little die area, which may benefit being as close to the memory as possible. By having a function like Burst on the die, it helps to minimize the traffic on a control bus that would otherwise need to issue the repetitive read or write commands. Since an access to and from the bandwidth engine device is a 72b structure and many of the accesses to memory are larger (up to 576b), it has a beneficial effect of issuing one command and getting a 576b results. This allows the host a few free cycles to perform other tasks, therefore increasing the efficiency and throughput at the system level.
