Vadd 2 Kernel Clocks (RTL Kernel)¶
This example shows vector addition with 2 kernel clocks using RTL Kernel.
KEY CONCEPTS: RTL Kernel, Multiple Kernel Clocks
KEYWORDS: kernel_frequency
This example demonstrates the use of two kernel clocks
for a simple
case of vector addition.
An RTL kernel can have up to two external clock interfaces; a primary
clock, ap_clk
, and an optional secondary clock, ap_clk_2
. Both
clocks can be used for clocking internal logic. However, all external
RTL kernel interfaces must be clocked on the primary clock. Both primary
and secondary clocks support independent automatic frequency scaling.
These clock frequencies are specified at V++ linking stage in the following manner.
kernel_frequency=0:150|1:250
DESIGN FILES¶
Application code is located in the src directory. Accelerator binary files will be compiled to the xclbin directory. The xclbin directory is required by the Makefile and its contents will be filled during compilation. A listing of all the files in this example is shown below
src/hdl/krnl_vadd_2clk_rtl.v
src/hdl/krnl_vadd_2clk_rtl_adder.sv
src/hdl/krnl_vadd_2clk_rtl_axi_read_master.sv

COMMAND LINE ARGUMENTS¶
Once the environment has been configured, the application can be executed by
./host <vadd XCLBIN>
