AXI Test IP#
This IP-Core is used for testing the AXI communication between PS and PL.
The IP-Core calculates \(C=A \cdot B\) with different data types.
For all data types except for the float
calculation, the input and output values are scalar.
The float
calculation input and output is a 2x2
matrix.
Use this IP-Core to test read/write operations by AXI between PL and PS using the Hardware Abstraction Layer.

Driver function reference#
-
typedef struct uz_myIP2_t uz_myIP2_t#
Data type for object myIP2.
-
struct uz_myIP2_config_t#
Configuration struct for myIP2.
-
uz_myIP2_t *uz_myIP2_init(struct uz_myIP2_config_t config)#
Initializes and instance of the myIP2 driver.
- Parameters:
config – Configuration values for the IP-Core
- Returns:
Pointer to initialized instance
-
int32_t uz_myIP2_multiply(uz_myIP2_t *self, int32_t A, int32_t B)#
Calculates C=A*B.
- Parameters:
self – Pointer to IP-Core instance that was initialized with init function
A – First factor
B – Second factor
- Returns:
Product of A times B
