Ram 1k

[GUN]

while im trying to get better at lua coding, i made a 1k ram with 1024 write/readable addresses

GateActions["ram1k"] = {
    group = "Memory",
    name = "RAM(1kb)",
    inputs = { "Clk", "AddrRead", "AddrWrite", "Data", "Reset" },
    output = function(gate, Clk, AddrRead, AddrWrite, Data, Reset )
    if (Reset > 0) then
            gate.LatchStore = {}
    end

        AddrRead = math.floor(tonumber(AddrRead))
        AddrWrite = math.floor(tonumber(AddrWrite))
        if (Clk > 0) then
            if (AddrWrite < 1024) then
                    gate.LatchStore[AddrWrite] = Data
            end
        end
        return gate.LatchStore[AddrRead] or 0
    end,
    reset = function(gate)
        gate.LatchStore = {}
    end,
    label = function(Out, Clk, AddrRead, AddrWrite, Data, Reset )
        return "WriteAddr:"..AddrWrite.."  Data:"..Data.."  Clock:"..Clk.."  Reset:"..Reset..
            "\nReadAddr:"..AddrRead.." = "..Out
    end,
    ReadCell = function(dummy,gate,Address)
    if (Address < 0) || (Address > 1024) then
        return 0
    else
        return gate.LatchStore[Address] or 0
    end
    end,
    WriteCell = function(dummy,gate,Address,value)
    if (Address < 0) || (Address >     1024) then
        return false
    else
        gate.LatchStore[Address] = value
        return true
    end
    end
}

and i also added a wire able Reset to the increment/decrement counter

GateActions["increment/decrement"] = {
    group = "Arithmetic",
    name = "Increment/Decrement",
    inputs = { "A", "Increment", "Decrement", "Reset" },
    output = function(gate, A, Increment, Decrement, Reset)
        local increment = ( Increment > 0 )
        local decrement = ( Decrement > 0 )
        local reset = ( Reset > 0 )
        
        if ( gate.PrevValue ~=  increment ) then
            gate.PrevValue = increment
            if ( increment ) then
                gate.Memory = (gate.Memory or 0) + A
            end
        end
        
        if ( gate.PrevValue ~=  decrement ) then
            gate.PrevValue = decrement
            if ( decrement ) then
                gate.Memory = (gate.Memory or 0) - A
            end
        end
        
        if ( reset ) then
            gate.Memory = 0    
        end
        
        return gate.Memory
    end,
    label = function(Out, A)
        return "(" .. A .. " +/- LastNum) = " .. Out
    end
}

add to the svn if possible please

I might make a RAM tool that allows you to have a custom amount of values.

hm.. that actually doesn't sound bad at all

I already added that to the uwsvn, called it "Dynamic memory". It even allows to save the values stored in it when duplicating.

There's 128KB RAM in SVN already, so is 4KB ram (64x64 store)

how did you get the values to be able to duplicate?
