    I'm very new to Verilog and I've tried to create single-cycle 32bit MIPS processor. Instructions I want to implement are add, and, addi, addu.qb, addu_s.qb, beq, jal, jr, lw, or, slt, sub, sw but I and must be instantiated directly in the VHDL or Verilog code. This violates the goal of vendor independence; how-ever, it is currently a limitation of most synthesis compilers. When instantiation is required, datapath macros are auto-matically generated by interactively accessing the ACTgen Macro Builer that is described in the following section.

    Below is Verilog code showing how to create a shift register. Shift registers are very important for aligning data in your FPGA. The shift operator makes this code clean and compact. The shift register is 4 clock cycles long. It will delay any input by 4 clock cycles.

    I am implementing a new processor in verilog. I am no near the execution unit implementation!! Does any one have (or know) a full design of RISC-style instructions execution unit in verilog. I am planning to implement 1 ALU unit, 1 Branch unit, 1 SET unit, and 1 LDST unit. I really need the unit..please help. /Ben UEC, IS , Tokyo These comparators increased the width of the datapath, and a small amount of zipper logic increased the height. These changes also produced a much smaller controller than originally planned. Figure 3: Datapath (red = counter, blue = comparator, green = zipper logic) The datapath (slice plan shown in Figure 3) is a series of counters and ...

    compiler generates code to control the datapath at every clock cycle. However, instead of using any abstraction such as instruction-set or microcode, the NISC compiler directly generates the control signal values of every component in the datapath for every clock cycle. A NISC designer needs to only focus on designing the datapath, i.e.
