Meta Functional Description
Epiphany Memory Map
Each Epiphany chip in the Meta system has a unique memory range set through on-board resistors and the ROW/COLUMN coodinate set with dip-switches on the Meta-Carrier. The following table shows the offset of each core within the Meta System. To get the exact absolute address offset for an Epiphany core, add together the address module address, chip address, and core address.
For example, the offset address of core (0,0) in chip (0,2) on module (2,0) would be : 0x80800000

Elink Connectors
Each Meta-Module has four Epiphany-elink board to board connectors (north, east, west, south), with each connector supporting four independent bidirectional Epiphany elinks. The Meta-Module connects to the Meta-Carrier as a tightly coupled sandwich.
The Elink connector pinout is shown in the following tables.
Table: South and West Elink Connectors
| Pin # | Signal | Pin # | Signal | Pin # | Signal | Pin # | Signal |
|---|
Control Connector
The reset and clocking signals for the Meta-Module is provided by the Meta-Carrier through the control connector.
