+Version

+ Revision: #3, November 17th, 2017
+
+Number
+
+ OpenCL Extension #?
+
+Status
+
+ Complete.
+
+Extension Type
+
+ OpenCL device extension
+
+Dependencies
+
+ Requires OpenCL version 1.2 or later.
+
+Overview
+
+ This extension adds built-in functions giving direct access to specialised
+ integer dot product instructions that are supported on some devices. An
+ application wishing to support a fallback path for devices where a specific
+ function is not available may use the following pattern:
+
+ #ifdef cl_arm_integer_dot_product_XXX
+ #pragma OPENCL EXTENSION cl_arm_integer_dot_product_XXX : enable
+ code using arm_dot_xxx()
+ #else
+ alternative implementation
+ #endif
+
+Header File
+
+ cl_ext.h
+
+New Procedures and Functions
+
+ Built-in Functions
+
+ int arm_dot(char4 a, char4 b);
+ uint arm_dot(uchar4 a, uchar4 b);
+
+ Description
+
+ These functions are available when cl_arm_integer_dot_product_int8 is reported.
+ The cl_arm_integer_dot_product_int8 preprocessor macro is then defined.
+
+ The value returned is:
+
+ (a.x * b.x) + (a.y * b.y) + (a.z * b.z) + (a.w * b.w).
+
+ Operands are zero- or sign-extended to 32-bit before the multiplications.
+
+ Built-in Functions
+
+ int arm_dot_acc(char4 a, char4 b, int acc);
+ uint arm_dot_acc(uchar4 a, uchar4 b, uint acc);
+
+ Description
+
+ These functions are available when cl_arm_integer_dot_product_accumulate_int8
+ is reported. The cl_arm_integer_dot_product_accumulate_int8 preprocessor
+ macro is then defined.
+
+ The value returned is:
+
+ acc + [ (a.x * b.x) + (a.y * b.y) + (a.z * b.z) + (a.w * b.w) ].
+
+ Operands are zero- or sign-extended to 32-bit before the multiplications.
+
+ Built-in Functions
+
+ int arm_dot_acc(short2 a, short2 b, int acc);
+ uint arm_dot_acc(ushort2 a, ushort2 b, uint acc);
+
+ Description
+
+ These functions are available when cl_arm_integer_dot_product_accumulate_int16
+ is reported. The cl_arm_integer_dot_product_accumulate_int16 preprocessor
+ macro is then defined.
+
+ The value returned is:
+
+ acc + [ (a.x * b.x) + (a.y * b.y) ].
+
+ Operands are zero- or sign-extended to 32-bit before the multiplications.
