That's what the values are to the verilog code (if declared as signed). wire signed [7:0] a = 8'b11001110; wire signed [7:0] b = 8'b01010010; wire signed [15:0] c = a*b; C is 11101111 11111100 or -4100 in signed decimal Not open for further replies. Similar threads ...
As a beginner, I am attempting to write Verilog code for a basic 16-bit ALU and execute it on a Spartan 6 FPGA. The ALU specifically handles signed operations and does not include any unsigned operations. All input variables are signed wires, and the output is stored in a designated desti...
In this chapter we will describe these methods and illustrate them with VHDL and Verilog.

By employing these Veda ganitha sutras in the computation algorithms of the ALU, the complexity, execution time, area, power etc can be reduced. In this work, Verilog HDL has been used to code the algorithms...

Suppose the multiplication or division can been done in one clock, it can use the pipeline realize it as the following verilog code: always@(clk) begin a1 <= a; b1 <= b; b2 <= b1; b3 <= b2; z1 <= z; z2 <= z1; pipe0 <= x*y; //delay ...
Current high level synthesis flows identify multiplication operations by the presence of multiplication operator in the program. The multiplication operator is “*” in C, C++, Verilog, and VHDL. Every instance of “*” in the program is treated equally without any distinction as to whether...
Data formats in which such descriptions may be implemented include, but are not limited to: formats supporting behavioral languages like C, formats supporting register transfer level (RTL) languages like Verilog and VHDL, formats supporting geometry description languages (such as GDSII, GDSIII, GDSIV...
