Multiplication/Division Unit
The Multiplication/Division Unit (MDU) provides fast 16-bit multiplication, 16-bit and
32-bit division as well as shift and normalize features. It has been integrated to support
the SAL-XC886 Core in real-time control applications, which require fast mathematical
computations.
Features
Fast signed/unsigned 16-bit multiplication
Fast signed/unsigned 32-bit divide by 16-bit and 16-bit divide by 16-bit operations
32-bit unsigned normalize operation
32-bit arithmetic/logical shift operations
Table 27 specifies the number of clock cycles used for calculation in various operations.
