In this section:
Syntax
void __RMPA_B(signed char * v1, signed char * v2, unsigned long n, rmpa_t * acc);
Description

Inserts an RMPA.B instruction. The RMPA instruction sequentially multiplies the two vectors v1 and v2 and adds each product to the accumulator acc. The length of the vectors is n. You can supply an initial value for the accumulator acc, either variable or a constant. The type rmpa_t is declared in the intrinsics.h file.

Note

To use intrinsic functions in an application, you must include the header file(s) where they are declared, see Summary of intrinsic functions.
