MVTX2601
Data Sheet
14
Zarlink Semiconductor Inc.
Up to 1 K Ethernet frame buffers are supported and they will use 1.5 MB of memory. Each frame uses 1536 bytes.
The maximum system memory requirement is 2 MB. If less memory is desired, the configuration can scale down.

5.0 Search Engine
5.1 Search Engine Overview
The MVTX2601 search engine is optimized for high throughput searching, with enhanced features to support:
Up to 64 K MAC addresses
2 groups of port trunking
Traffic classification into 4 transmission priorities, and 2 drop precedence levels
Flooding, Broadcast, Multicast Storm Control
MAC address learning and aging
Port based VLAN
5.2 Basic Flow
Shortly after a frame enters the MVTX2601 and is written to the Frame Data Buffer (FDB), the frame engine
generates a Switch Request, which is sent to the search engine. The switch request consists of the first 64 bytes of
the frame, which contain all the necessary information for the search engine to perform its task. When the search
engine is done, it writes to the Switch Response Queue and the frame engine uses the information provided in that
queue for scheduling and forwarding.
In performing its task, the search engine extracts and compresses the useful information from the 64-byte switch
request. Among the information extracted are the source and destination MAC addresses, the transmission and
discard priorities, whether the frame is unicast or multicast. Requests are sent to the external SRAM to locate the
associated entries in the external hash table.
