therefore fewer I/O pins. The T2081 is pin compatible with the lower end T104x and T102x parts. T1 The T1 family uses the e5500 64-bit single threaded core at 1.2 to 1.5 GHz with 256 kB L2 cache per core and 256kB shared CoreNet L3 cache. T1040 – Quad-core, four Gbit Ethernet ports and an 8 port Ethernet switch T1042 – Quad-core, five Gbit Ethernet ports, no Ethernet switch. T1020 – Dual-core, four Gbit Ethernet ports and an 8 port Ethernet switch T1022 – Dual-core, five Gbit Ethernet ports, no Ethernet switch. System design Networking, IT and telecommunication systems The QorIQ products bring some new challenges in order to design some control planes of telecommunication systems and their data plane. For instance, when 4 or 8 cores are used, such as the P4080, in order to achieve millions of Packet Processing per seconds, the system does not scale with regular software stack because so many cores require a different system design. In order to restore simplicity and still get the highest level of performance, the telecommunication systems are based on a segregation of the cores. Some cores are used for the control plane while some others are used for a re-designed data plane based on a Fast Path. Freescale has partnered with networking company 6WIND to provide software developers with a high-performance commercial packet processing solution for the QorIQ platform.
