Fixed cycle delay: Difference between revisions

Revision as of 15:17, 19 March 2016

Delay code

Shortest possible CPU code that creates N cycles of delay, depending on constraints.

All code samples are written for CA65.

Assumptions:

No page wrap occurs during any branch instruction. If a page wrap occurs, it adds +1 cycle for each loop, completely thwarting the accurate delay.
No interrupt / NMI occurs during the delay code. Code samples where an interrupt could cause data corruption are separately indicated.

It is possible to verify on compile time that no page wrap occurs, by replacing all branches with these macros:

.macro branch_check opc, dest
    opc dest
    .assert >* = >(dest), warning, "branch_check: failed, crosses page"
.endmacro
.macro Jcc dest
        branch_check bcc, dest
.endmacro
.macro Jcs dest
        branch_check bcs, dest
.endmacro
.macro Jeq dest
        branch_check beq, dest
.endmacro
.macro Jne dest
        branch_check bne, dest
.endmacro
.macro Jmi dest
        branch_check bmi, dest
.endmacro
.macro Jpl dest
        branch_check bpl, dest
.endmacro
.macro Jvc dest
        branch_check bvc, dest
.endmacro
.macro Jvs dest
        branch_check bvs, dest
.endmacro

It is permissible for DMA to steal cycles during the loops. If you are expecting that to happen, you have to manually adjust the delay cycle count (and it is in fact possible to do so) in order to get the correct delay.

Explanations on the requirements:

@zptemp means you have a zeropage address that you can write random data into.
@rti means you have a dummy interrupt handler installed that does nothing but RTI.
@rts12 means you know a memory address that contains byte $60 (RTS).
@rts14 means you know a memory address that contains a harmless 2-cycle instruction that fits your constraints (such as CLC, LDA #0, or NOP), followed by RTS.
@rts15 means you know a memory address that contains a JMP that jumps to another location that contains RTS. Alternatively, it means you know a memory address that contains a harmless 3-cycle instruction that fits your constraints (such as LDA $00), followed by RTS.
delay_a_25_clocks, delay_256a_16_clocks, delay_256a_x_33_clocks, delay_256a_x_31_clocks, and delay_256x_a_30_clocks are defined at Delay code.
"Unsafe for interrupts" means that even though the S register is not clobbered, data corruption will occur if an interrupt/NMI happens in the middle of the delay code.

2 cycles

1 bytes
EA NOP	No requirements

All instructions cost at least 2 cycles. There is no way to do 1 cycle of delay (though −1 cycles may sometimes appear in branch cost calculations).

3 cycles

1 bytes
48 PHA	Clobbers S; and writes in stack
2 bytes
C5 C5 CMP $C5	Clobbers Z&N, and C
24 24 BIT $24	Clobbers Z&N, and V
A5 A5 LDA $A5	Clobbers A, and Z&N
A6 A6 LDX $A6	Clobbers X, and Z&N
A4 A4 LDY $A4	Clobbers Y, and Z&N
85 xx STA @zptemp	Requires @zptemp
04 04 NOP $04	Requires support for unofficial opcodes
3 bytes
4C xx xx JMP *+3	Not relocatable code

Not relocatable means that the target address is hardcoded into the code. In ROM hacking, it sometimes makes sense to move code blobs around, and a hardcoded address makes it difficult to relocate the code. This restriction does not apply to branches, which use relative addressing. It is also assumed to not apply to JSR instructions, as chances are the JSR target is outside the code being relocated.

4 cycles

1 bytes
68 PLA	Clobbers A, S, and Z&N
2 bytes
EA ... NOP × 2	No requirements

zp-indexed modes such as LDA $00,X also do 4 cycles, but having side effects, these two-byte instructions are inferior to a simple 2 × NOP.
There is also an unofficial opcode NOP $00,X (34 00), but there is no reason to use this instruction when the official equivalent has the same performance.

5 cycles

EA NOP 85 xx STA @zptemp	Requires @zptemp
EA NOP 04 04 NOP $04	Requires support for unofficial opcodes
4 bytes
EA NOP 4C xx xx JMP *+3	Not relocatable code

abs-indexed modes such as LDA $1234,X cause 4 or 5 cycles of delay, depending whether a page wrap occurred. Because you need extra setup code to make sure that a wrap does occur, you do not see this mode in these samples, outside situations where circumstances permit.

6 cycles

2 bytes
F6 F6 INC $F6,X	Clobbers Z&N; and requires @zptemp, and writable $00-$FF
48 ... PHA × 2	Clobbers S; and writes in stack
EA NOP 68 PLA	Clobbers A, S, and Z&N
3 bytes
EA ... NOP × 3	No requirements

zp-indexed RMW instructions such as INC @zptemp,X do 6 cycles. Unless we know the value of X, it might write into any address between $00-$FF. This option is only useful if the entire range of $00-$FF is free for clobbering with random data, or if X has a known value.
ix instructions like LDA ($00,X) do 6 cycles, but the value of X decides where a pointer is read from, and said pointer can point anywhere. We only do that when the value of X is known.
iy instructions like LDA ($00),Y also do 5-6 cycles, but in addition to the note above, we cannot predict whether a wrap occurs or not. So we don't use this mode.
Absolute RMW instructions like INC $4018 do 6 cycles, but weighing 3 bytes with side-effects it would be inferior to 3 × NOP.

PHP-PLP is very efficient for 7 cycles of delay, but it does modify stack contents. S register remains unchanged though.
PLA-PHA does not overwrite any bytes in stack. It just writes back the same byte. But it does clobber A and Z+N.
abs-indexed RMW instructions such as INC abs,X do 7 cycles. We only do this either we know the value of X, or when the entire 256-byte page can be safely overwritten with random data.

4 bytes

Unofficial ix and iy RMW instructions such as SLO ($00,X) or SLO ($00),Y would do 8 cycles for 2 bytes of code. We only do that if we know X or Y to be zero, and we have a known pointer to safely rewritable data.

Jumping into the middle of another instruction and thereby reusing code is a very efficient way of reducing code size. Note that all code samples using branches on this page require that no page wrap occurs.

JSR-RTS causes 12 cycles of delay. But it does write a function return address in the stack, which may be unwanted in some applications. S is not modified.
Again, ROL-ROR does not have side effects (as long as an interrupt does not happen in the middle), except for Z+N.
