+=== Levels
+
+A TOSA level defines operator parameter ranges that an implementation shall support.
+This is distinct from a profile that defines the operations and data-types supported.
+This version of the specification defines two TOSA levels:
+
+* No level : allows the full range of parameters specified by the operations according to the operation data types.
+* Level 8K : ranges are expected to be sufficient for applications with frame sizes up to 8K.
+
+Later versions of the specification may define additional levels.
+The following table defines the value ranges for Level 1.0.
+These ranges are checked using the LEVEL_CHECK() function with the operator descriptions.
