Unique techniques such as eight-way multithreading, zero-cycle context switching and a memory-to-memory architecture deliver the necessary performance, reduced cost and size required by wireless applications.iaqs iaqs iaqs iaqs iaqs iaqs Eight-way multithreading allows the device to effectively operate as eight separate processors, where each thread can be assigned a variable speed from 0 - 250 MHz in 3.9 MHz increments. As many as six threads can be dedicated to software I/O. In addition, because packet processing doesn't require ongoing access to data by the CPU, on-chip caching isn't necessary. The use of a memory-to-memory architecture allows packets to be processed directly in on-chip memory, eliminating the need for caches, and avoiding cache misses which reduce performance. Memory-to-memory also eliminates the costly silicon needed for caches and off-chip memory.iaqs iaqs iaqs iaqs iaqs iaqs These capabilities allow the IP3023 to deliver wire-speed performance in one-fourth the silicon area and requires only 10 percent of the off-chip memory employed by traditional architectures. This leads to a lower overall bill of materials (BOM) for designs based on the IP3023. |

| 1 | ken7976 | Hi Dainis, I'm expected to feel your fingers burned by this new Multithreaded Architecture for Software I/O (MASI). Sounds great. I know that before using IP2022 your opinions look very sceptical about "software" based Ethernet controller (Serializer and Deserializer unit). This software I/O approach looks even greater. Hope Ubicom politics will change a little bit, at least revealing more about MASI in the near future. Even under NDA cover. Regards, Silvio |
