This is clearly five delay registers with 32 bits each. On some FPGAs (Xilinx in particular), the synthesizer detects this as a shift register if only the last value (@d4) is used, and there's no reset on any of these registers. This can reduce the consumption of logic considerably....
Start by adding the first byte as the first 8 bits of a 32-bit unsigned integer. packedNum = byte1; Next, pack the other three bytes intopackedNum, usingbitshiftto shift the bytes to the proper locations, andbitorto copy the bits over. ...
Fixed-point quantization has traditionally been one of the most challenging tasks in adapting an algorithm to target FPGA or ASIC hardware. Native floating-point HDL code generation allows you to generate VHDL or Verilog for floating-point implementation in hardware witho...

to carry over, lets call these bits [16..0] The result port of the LPM will give you bits [15..0] of the answer and [16] will wire up to the "cout" signal (carry out) So if you want the full 17 bits of resolution just combine the cout to the result like this (verilog):...

Return the minimum flips required in some bits of a and b to make ( a OR b == c ). (bitwise OR operation). Flip operation consists of change any single bit 1 to 0 or change the bit 0 to 1 in their binary representation. Example 1: Input: a = 2, b = 6, c = 5 Output: ...
With the Crossbar, all devices are usable simultaneously if they fit in the FPGA. As not everything lives in the same clock domain, the design also use a Wishbone CDC, a wrapper around the one from Verilog Wishbone Components. The software Directory 'NetBSD' Some basic drivers for NetBSD ...
All the examplesfrom the Tiny Tapeout SDK run cocotb tests on the RP2040 and interact with actual projects on the ASICs. These were ported in from those used during Verilog development of the projects, and remain mostly as-is. Using theSUB, to talk to projects through an FPGA over USB (...
