Important: the Mono.Simd assembly is a work-in-progress API
|
||
|
|
and has not been finalized. We are publishing the assembly
|
||
|
|
and the documentation hoping to get input and feedback from
|
||
|
|
the community.

The Mono.Simd namespace provides a number of classes that are
|
||
|
|
hardware accelerated by mapping the classes and the actual
|
||
|
|
operations to native SIMD instructions on a processor.

When the Mono runtime's SIMD optimization are active the
|
||
|
|
operations on the structures defined in this namespace are
|
||
|
|
mapped to hardware operations which can improve the
|
||
|
|
performance of your graphics, multimedia or 3D operations
|
||
|
|
significantly.

Code that uses the types defined in the Mono.Simd assembly
|
||
|
|
will work even on systems that do not have hardware SIMD
|
||
|
|
operations, systems where Mono has not added support for the
|
||
|
|
native SIMD operations and even on the Microsoft.NET runtime
|
||
|
|
as it currently does not have support for hardware accelerated
|
||
|
|
SIMD operations.

You can control whether the runtime will map the operations to
|
||
|
|
SIMD primitives by using the -O command line option and
|
||
|
|
specifying -O=simd to enable or -O=-simd to disable.

The operations that are hardware accelerated are flagged with
|
||
|
|
the Acceleration attribute on each individual method. The
|
||
|
|
Mode property describes the minimum version of CPU
|
||
|
|
functionality required to use the operation. Software can
|
||
|
|
use this flag to determine if they want to use the operations
|
||
|
|
implemented in software or not.

Casting operations are also cheap, converting from one data
|
||
|
|
type to another have a very low cost. This is useful to move
|
||
|
|
information back and forth from floating point values to
|
||
|
|
integers.
