![]() ![]() Yes PowerShell is powerful enough for that and many people do write WinForm apps in PowerShell. 'This is an emoji' + ::ConvertFromUtf32(0x1F60A) ![]() Some examples: 'somestring'.Substring(4) * 3 -replace 'ings', 'eet' You can also do advanced string and regex manipulation. For more information read about the formatting operator. For example convert from raw Epoch values to datetime and vice versa ::FromFileTime(0x01d15614cbaee92c) Here are some other things that may be useful to programmers:Ĭalculate file or object sizes: Use number suffixes 12.5GB + 5.8MB + 1392KB for binary units and 12.5e9 + 5.8e6 + 1392e3 for decimal units (G = 1e9, M = 1e6, K = 1e3)Ĭonvert to/from base64: ::ToBase64String and ::FromBase64Stringĭate/time manipulation. The math functions above are mainly from the. NET or Win32 functions (or even Linux functions in *.so files) can be called from PowerShell. Not only does it has a 64-bit unsigned type (and 128-bit signed/unsigned types since PowerShell Core 7.0) but it also has an arbitrary-precision integer type. Yeah, I think I need to write some test code.PowerShell can solve all of your problems. We have maybe 100 calculations to do and 167772 cycles to do them in. Doesn't matter how many steps it takes really. Is this controlling the multiplier to allow it to be used for either signed or unsigned numbers? Unsigned would be great! The subtract input allows me to subtract values without complementing them and the accumulator feedback allows values to be added through sequential load and accumulate steps. These 36 bit numbers are multiplied using the VHDL operator defined in use IEEE.STD_LOGIC_UNSIGNED.ALL Īssigning the result to a 72 bit signal which is then truncated to the 36 lsbs. I see logic that clearly control the sign extension of the 18 bit multiplier inputs to 36 bits. Initially I had hoped they would be to control if the inputs were complemented to allow for subtraction and such, but they are for controlling the use of the sign bit. The code shows signals named ASIGN and BSIGN. The program offers up to 50-decimal precision and gives users the possibility of selecting the numeral system (binary, octal or hexadecimal) and picking the radix character and angle unit (radian. ![]() However, I think I may have gleaned a bit of insight from a comprehensive block diagram in the main document combined with the simulation source code for the block in the mode I will be using. The documentation on this DSP unit is truly abysmal lacking much detail at all. It is hard to imagine the multipliers are not signed, but I'm not sure. Seems that unlike addition, multiplication hardware is different for signed and unsigned numbers. Then someone asked me if these units were signed or unsigned. I was planning to use 18 bit data in Q1.17 format. It also subtracts a 54 bit input from the 55 bit accumulator at the same time. These units accept two 18 bit inputs for the multiplier adding the 36 bit result into the 55 bit accumulator. I'm using the DSP unit (just a fancy name for the multiplier/accumulator unit) of the Gowin GW1N devices to do some fairly simple math. ![]()
