Crossbar switch - Wikipedia, the free encyclopedia (1899 words) |
 | Crossbar switches are sometimes referred to as "cross-point switches," "crosspoint switches," or "matrix switches." The other principal switch architectures are that of a memory switch or a crossover switch. |
| Crossbar switches have a characteristic matrix of switches between the inputs to the switch and the output of the switch. |
| Crossbar switches are most famously used in information processing applications such as telephony and packet switching, but they are also used in applications such as mechanical sorting machines with inputs. |
| Design Implementations of the Memory Crossbar (3689 words) |
| For a 20 mm chip and a 10 mm crossbar centered in the middle of the chip, this distance is 15 mm. |
| The extra area required for the self routing crossbar appears because M2 lines in the core circuit, shown in purple in figure 4.5, cannot be placed at the minimum spacing. |
| The width of the crossbar is fixed by either the width of the vector unit or the width of the chip; therefore, the area of the crossbar is not sensitive to the size of the switches. |
