Virtex-II, MULT18X18S - Where do I find documentation for a pipelined multiplier?

説明

Where do I find documentation for a pipelined multiplier?

ソリューション

MULT18X18S is a pipelined multiplier, and it is a registered (or 1-pipeline) version of MULT18X18. 

 

A brief description of this library component can be found in the Libraries Guide of the 4.1i Software Manual, located at: 

http://toolbox.xilinx.com/docsan/xilinx4/manuals.htm
 

MULT18X18S components are available in software versions 4.1i and later. The following VHDL/Verilog examples illustrate MULT18X18S instantiation.

 

VHDL 

 

component MULT18X18S 

port (A : in STD_LOGIC_VECTOR (17 downto 0); 

B : in STD_LOGIC_VECTOR (17 downto 0); 

C : in STD_ULOGIC ; 

CE : in STD_ULOGIC ; 

P : out STD_LOGIC_VECTOR (35 downto 0); 

R : in STD_ULOGIC ); 

 

end component;

 

Verilog 

 

module MULT18X18S (P, A, B, C, CE, R); 

output [35:0] P; 

input [17:0] A; 

input [17:0] B; 

input C, CE, R; 

endmodule;
