    Agreed. It must be a shift. Although an actual roll wouldn't look any different because any bits that wrap around are overwritten by the source data.

    Based on your description, should that be:
    		rolbyte	myreg,myreg2,#0		'results in myreg = $234567ef
    		rolbyte	myreg,myreg2,#1		'results in myreg = $234567cd
    		rolbyte	myreg,myreg2,#2		'results in myreg = $234567ab
    		rolbyte	myreg,myreg2,#3		'results in myreg = $23456789
    
    That would be true if those were each single instructions by themselves. Oz has treated them as altogether in sequence.

    Ah yes, I should have been a little more specific with my code example. Oops. Note added.

    Ahh! That makes sense.

    How about SLMBYTE (Shift Left, Move)?
  • ROLBYTS D,S#,#n
    Shift/Rotate D left 1 byte, and/but inserting the new byte 0 from S byte n.
  • HUBEXEC

    When I code for hubexec, I use an ORGH $xxxx statement.
    Now my code is being compiled for hub. All DJXX/JMP/CALLx instructions will use relative if possible.

    I presume when the DJxx/JMP/CALLx instructions are out of relative range, the direct hub address will be used.

    Everything seems fine so far.

    Has anyone thought about what happens when we want the code to be able to execute in both hubexec and cogexec/lutexec modes ??? We cannot let the compiler use direct mode.
  • IIRC Pnut always uses relative addressing unless a boundary is crossed(cog to hub) or forced to absolute with a "#\" prefix.

    JNP/CALL have +/- 19 bit relative range so should be no need to go absolute.
    I suspect that DJNZ can be augmented with AUGS to extend it's range too.

    Edit: Pnut allows DJNZ to use "##" to extend range
    		orgh	$1000
    
    djxx		mov	count,#55
    		long	0[$1_0000]	'64k of nop's
    		djnz	adra,##djxx
    		ret
    
  • I have found the ## to automatically insert the additional AUGS or AUGD instruction extremely useful. Lots of the extra instructions support the D/# variant.

    That DJNZ x,##y is another nifty use

    Yep, a great feature.
    Pnut even can do a double AUG insertion like
    	wrlong	##$1234_5678,##$3_ffb0
    
    An immediate 32 bit value to a immediate hub address, very cool! :cool:

    Ah ... oh ... huh? ... how does that work at the machine code level?
  • I think that is an AUGS and a AUGD before the actual opcode then.

            wrlong	##$1234_5678,##$3_ffb0
    translates to
            augd    #($1234_5678 >> 9)
            augs    #($3_ffb0 >> 9)
            wrlong  #($1234_5678 & $1FF),#($3_ffb0 & $1FF)

    I would have thought the AUGD gets applied to the AUGS, which would be a mess. There must be some special case detection when they get paired ... Has Chip talked about this before?

    EDIT: Maybe it's a bit like the SETQ instruction, ie: Internal registers for S and D that are specially preloaded by the AUGx instructions and not used until a non-AUGx instruction is executed. That would mean any number of AUG's can be sequenced... ?
  • They load up internal registers which get combined at the next "normal" instruction execution, which also resets those registers. There are S and D registers for AUGS and AUGD.

    There are also ALTS, ALTD, ALTI and ALTR instructions which can vary the following instructions S, D, I (instruction) and R (result) addresses.
  • Right. I had imagined all of those just fiddled the next instruction in the pipe. As per the documented descriptions.

    Maybe an improved description is in order.

  • Cluso,
    What's the diff between ******* and <empty>?
  • Cluso99Cluso99 Posts: 16,170
    edited 2016-06-29 - 11:43:20
    ******* is used in subsequent decoding.
    For example, the ******* in the SETNIB/GETNIB/ROLNIB/******* is divided into the next line SETBYTE/GETBYTE. So therefore
    ff=00 = SETNIB
    ff=01 = GETNIB
    ff=10 = ROLNIB
    ff=11 = SETBYTE if instr[0]=0, GETBYTE if instr[0]=1

    <empty> means the opcode if available. ie not used.
  • Chip,
    The second group (SETNIB...QVECTOR)

    I tried a few experiments attempting to work out how they work and this is what I found so far.

    ADDPIX seems to add the pixel bytes together and if the 8 bit add overflows the resultant pixel byte is set to $FF

    MULPIX appears to multiply the pixel bytes and stores the scaled pixel bytes.

    MIXPIX and BLNPIX seem to be affected by the contents of the SETPIX value?

    Any other pixel freaks out there played with these yet? :)


  • Ok, I found this in the old P2-Hot stuff.
    Looks like it should be the same in the new P2?
    PIXEL MIXER
    -----------
    
    Each cog has a pixel mixer called MIX that can combine two pixels in a sum-of-products
    operation, where:
    
      inputs:
    
        DA = D pixel A component (8 bits)
        DR = D pixel R component (8 bits)
        DG = D pixel G component (8 bits)
        DB = D pixel B component (8 bits)
    
        SA = S pixel A component or GETPIX A' component (8 bits)
        SR = S pixel R component or GETPIX R' component (8 bits)
        SG = S pixel G component or GETPIX G' component (8 bits)
        SB = S pixel B component or GETPIX B' component (8 bits)
    
      outputs:
    
        A' = ((DA * DAX  +  SA * SAX  +  255) / 256) max 255
        R' = ((DR * DRX  +  SR * SRX  +  255) / 256) max 255
        G' = ((DG * DGX  +  SG * SGX  +  255) / 256) max 255
        B' = ((DB * DBX  +  SB * SBX  +  255) / 256) max 255
    
    
    The DAX/DRX/DGX/DBX/SAX/SRX/SGX/SBX terms determine the type of mixing that will be done.
    The terms are configurable for the MIXPIX/GETPIX instructions, but fixed for the others:
    
        ADDPIX  D,S/#    - Add and clamp A:R:G:B components into D
    
                           DAX = $FF   SAX = $FF
                           DRX = $FF   SRX = $FF
                           DGX = $FF   SGX = $FF
                           DBX = $FF   SBX = $FF
    
    
        MULPIX  D,S/#    - Multiply A:R:G:B components into D
    
                           DAX = SA    SAX = $00
                           DRX = SR    SRX = $00
                           DGX = SG    SGX = $00
                           DBX = SB    SBX = $00
    
    
        BLNPIX  D,S/#    - Blend A:R:G:B components by SA into D
    
                           DAX = !SA   SAX = SA
                           DRX = !SA   SRX = SA
                           DGX = !SA   SGX = SA
                           DBX = !SA   SBX = SA
    
    
    Here is the general-purpose MIXPIX instruction:
    
        MIXPIX  D,S/#    - Mix A:R:G:B components according to SETMIX into D
    
    
    To configure for MIXPIX/GETPIX usage, the SETMIX instruction is used:
    
        SETMIX  D/#,S/#  - Set MIX configuration to D/#[8..0], S/#[31..0]
    
                           D/#[8..0]   sets M       - initialized to $001 *
    
                           S/#[31..24] sets DAB     - initialized to $00
                           S/#[23..16] sets DCB     - initialized to $00
                           S/#[15..8]  sets SAB     - initialized to $FF *
                           S/#[7..0]   sets SCB     - initialized to $00
    
    
            M[8] = 0 for long mode, where D and S pixels are 8:8:8:8 bit A:R:G:B
    
            M[8] = 1 for word mode, where D and S pixels are 1:5:5:5 bit A:R:G:B
    
                   1:5:5:5 pixels are expanded so that %A_BCDEF_GHIJK_LMNOP becomes
                   %AAAAAAAA_BCDEFBCD_GHIJKGHI_LMNOPLMN for the mixing computation.
                   When being packed back down to 1:5:5:5 bit A:R:G:B, the single A
                   bit will be 1 if the resultant A was not 0, and the R:G:B fields
                   will be set to the top 5 bits of the resultant R:G:B.
    
                   In word mode, the low word in D will be operated on and the words
                   will be swapped, leaving the mixed pixel in the new high word and
                   the old high word in the new low word. Also, pixel data from S
                   will be taken alternately from the low and high word with each
                   operation, with SETMIX resetting the selector to the low word.
    
                   Word mode affects all ADDPIX/MULPIX/BLNPIX/GETMIX/GETPIX.

          * M and SAB are initialized on cog start so that GETPIX will return the
            scaled A:R:G:B texture pixel without any blending.
    
    
    The PIXADD/PIXMUL/PIXBLN/PIXMIX instructions all take 2 clocks, while GETPIX
    takes 3 clocks.
    



  • Has anyone used ALTI/ALTR/ALTD/ALTS or seen a recent writeup of these instructions?

    The ALTx instructions modify the next instruction whereas SETx modifies the cog ram contents.
    The SETx instructions also requires 2 spacer instruction.

    I think the ALTx instructions will likely be generated automatically by compilers or assemblers and not be coded directly.

    Do you mean AUGS & AUGD?
