The Ayama 10000 device consists of M × 72-bit (M = 256K for CYNSE10512, 128K for CYNSE10256, 64K for CYNSE10128)
storage cells referred to as data bits. There is also a mask cell corresponding to each data cell. A database entry includes both
the data and mask cells. Figure 3-1 shows the four possible table width sizes of the data and mask cells and the maximum possible
table depth for each width.
The Ayama 10000 can be configured to contain tables of different widths in one device up to a maximum equal to 512K/256K/128K
72-bit entries. For example, a single Ayama 10000 device can have both a 5-Tuple Flow table and an IPv6 forwarding table.
Figure 3-2 shows a sample configuration of multiple table widths in a CYNSE10512 device.
