Overview
|
||
|
|
--------
|
||
|
|
QorIQ LS1012A Development System (LS1012AQDS) is a high-performance
|
||
|
|
development platform, with a complete debugging environment.
|
||
|
|
The LS1012AQDS board supports the QorIQ LS1012A processor and is
|
||
|
|
optimized to support the high-bandwidth DDR3L memory and
|
||
|
|
a full complement of high-speed SerDes ports.
