Bassano del Grappa, Italy - 22, February 2011

ACube Systems is pleased to announce a new release of the U-Boot firmware for its line of motherboards Sam440ep and Sam440ep-flex.


What's new in this version:

* improved DDR setup:
Sam440ep-flex: 25% faster write speed, 10% faster read speed
Sam440ep-mini: 25% faster write speed

* doesn't scroll anymore the text from the SLB output, this allows a slight faster boot

* minor fixes when enabling video output on several gfx cards

Sounds like another nice update that will hopefully bring smooth DVD playback one stage closer on my little sam440ep 667MHz system.

Does this mean we don't have to run the other fix anymore then?

Glad to see constant improvements!
Hope in the end NO ONE will complain on speed part of SAM Amigas

Thanks for the update, good to see the 440 still being supported despite the arrival of the 460. I'm sure day to day tasks, like web browsing, seem smoother and snappier on my Sam440-flex with these recent updates.

@Vox
If no one complains about the speed of the SAM boards it will mean that all development of (CPU intensive) software has stopped, that would be a bad thing

But it's nice to see Acube constantly doing improvements and fine tuning everything.

@Valiant
If you are refering to the set-up file you placed in WBStart-UP at the moment it must be left there, otherwise you will lose the "read" improvement on the Video Bus (without it resets to the older 16Mb value, Write stays unchanged).

Anyway some better performance can be felt, which is a good thing

Even more (updates) are welcome of course

@TRiels

Got me there, but to my believe 500-800Mhz PPC if DSP was used would be satisfactory for Office and Browser too ...

If I recall previous IBM supercomputer used to use exactly same CPU just soo many
So why one wouldnt be good enough? Both this kind of "bottle necks" optimization and some software optimization of OS4 is most welcome!

You know what I ment ... more power to the people, not no new hardware

@thread

we've had several performance-related updates from acube, both u-boot and otherwise, for a while now. does anyone have benchmark numbers from before all the updates started a few months ago and want to compare them with the latest and greatest (u-boot 1.3.1d and sam440ep_setup)?

Well, there are for sure many other improvements that can be used.

This is for example an optimized memory copy function for the 440 processors (IBM docs)

(the documentations was already sent to the interested people)
I hope im more and more improvements deeply lurking in the 440 specific programming model.

memcopy example:

function_prolog(fast_440_copy)
61 // touch this code into the cache
62 mflr r0 // save lr
63 bl 4 // get our code address in lr
64 mflr r6 // in r6
65 mtlr r0 // restore lr
66 addi r7,0,0 // initialize r7 to 0
67 addi r0,0,0x10
68 mtctr r0 // initialize ctr to 0x10 lines
69 itouch_loop:
70 icbt r6,r7 // touch line into i-cache
71 addi r6,r6,0x20 // move to next line
72 bdnz itouch_loop // repeat
73
74 // initialize r6 for use in dcbt and dcbz's.
75 // also adjust the data pointers to work with load/store update
76 addi r6,0,4
77 subf r4,r6,r4
78 subf r3,r6,r3
79
80 // pre-touch and pre-zero two lines of the source and destination
81 // leaving r6 offset pointing to next untouched line
82 // Note that the order must be dcbt, dcbt, dcbz, dcbz
83 dcbt r4,r6
84 addi r6,r6,0x20
85 dcbt r4,r6
86 addi r6,r6,-0x20
87 dcbz r3,r6
88 addi r6,r6,0x20
89 dcbz r3,r6
90 addi r6,r6,0x20
91
92 addi r5,r5,-2 // subtract 2 from count
93 mtctr r5 // and put in ctr
94
95 cache_copy_loop:
96 dcbt r4,r6 // touch 2 lines ahead
97 lwzu r0,4(r4) // load 8 registers from cache
98 lwzu r5,4(r4)
99 lwzu r7,4(r4)
100 lwzu r8,4(r4)
101 lwzu r9,4(r4)
102 lwzu r10,4(r4)
103 lwzu r11,4(r4)
104 lwzu r12,4(r4)
105 dcbz r3,r6 // zero 2 lines ahead
106 stwu r0,4(r3) // store 8 registers to cache
107 stwu r5,4(r3)
108 stwu r7,4(r3)
109 stwu r8,4(r3)
110 stwu r9,4(r3)
111 stwu r10,4(r3)
112 stwu r11,4(r3)
113 stwu r12,4(r3)
114 bdnz cache_copy_loop
115
116 // Copy last two lines of data without cache ops.
117 addi r0,0,2
118 mtctr r0 // set ctr to 2
119 final_copy_loop:
120 lwzu r0,4(r4) // load 8 regs
121 lwzu r5,4(r4)
122 lwzu r7,4(r4)
123 lwzu r8,4(r4)
124 lwzu r9,4(r4)
125 lwzu r10,4(r4)
126 lwzu r11,4(r4)

134 stwu r11,4(r3)
135 stwu r12,4(r3)

If you have a sam440ep mini-itx 667MHz board dont apply this update as it seems
to break DMA disk transfer and stop DVD Playback from being usable.

Before the update I could watch hole DVDs without problems (apart from a view dropped frames), Now DvPlayer always ether crashes after a few minutes or I start getting random blocks of colour instead of video playback.
