documents from cmosis

FergusL
guesst: I would have expected that from a TVlogic screen
47
19:56
FergusL
it's a control screen designed for on-camera use
48
19:57
FergusL
they aren't made for showing precisely what you're shooting
49
19:58
FergusL
rather showing something deliberatly wrong(~ corrected) for the sake of simply helping the operator what he needs to check

hello again Bertl, se6astian and all.
52
20:01
Bertl
wb bootstrap!
53
20:01
bootstrap
I've been performing some due diligence about everything related to this project.
54
20:01
bootstrap
howdy!
55
20:01
bootstrap
Sorry I've been silent, but it takes a while to get back up to speed on stuff like this.
56
20:01
bootstrap
Just last night I was looking into 10Ge PHYs.
57
20:02
bootstrap
Strange that nobody seems willing to let component prices be known without jumping through hoops.
58
20:04
Bertl
that is mostly because they want to sell them at the highest possible price
59
20:05
bootstrap
Sigh. I can't imagine how not knowing the price will get me to design them into products! :-o
60
20:05
Bertl
i.e. if the chip costs 10cent in production, it can be sold at 10 USD typical, but if you buy more, it can be 2USD or 1USD or even 20 cent :)
61
20:05
bootstrap
Fortunately I have an NDA with Marvell from during my camera project, so maybe they'll be quick.
62
20:06
bootstrap
Well, the chips like these are more likely $20 to $80 in 1K to 10K quantities.
63
20:06
bootstrap
I assume the chip business is all about amortizing their development costs.
64
20:07
bootstrap
In most cases, anyway.
65
20:07
bootstrap
When I just looked into FPGAs again recently, I was BLOWN AWAY by how much they imagine they can get for the more elaborate ones. They're just NUTS.
66
20:08
bootstrap
Take a $5 CPU... put it inside the FPGA... and they want $150 or $1500 extra for it. Yeah, right. Not from this kid.
67
20:09
bootstrap
They must be focused only on markets like MRI machines or something, where the cost of the machine is so high, the IC costs are irrelevant.
68
20:09
bootstrap
For those kinds of projects, the flexibility of the FPGA is "worth it".
69
20:11
bootstrap
Fortunately, the "logic element only" FPGAs are still within reach (cost wise), though still annoyingly expensive.
70
20:13
guesst
i do not see fpga cost to be expensive
71
20:13
guesst
they can do more than is required :)
72
20:13
bootstrap
I assume you're talking about the LE-only variety.
73
20:13
guesst
yes
74
20:14
bootstrap
Yes, they are within rearch for this kind of project.... but MUCH too expensive for many other projects they would be nice for.
75
20:14
guesst
zynq make sense if you need more than 5Gbps between cpu-logic, but that much data the cpu can not process anyway
76
20:14
guesst
eg?
77
20:14
bootstrap
?
78
20:14
bootstrap
What is zynq? Xilinx?
79
20:15
guesst
yes. fpga+arm
80
20:15
bootstrap
I've been looking at Altera, because that's what I'm familiar with.
81
20:15
guesst
the price is > than a fpga + discrete arm... only benefit is sharing the memory :)
82
20:15
bootstrap
In their case, the new generation of LE-only ones are about $60... but add a microcontroller, and the price goes through the roof.
83
20:16
guesst
it is not a microcontroller
84
20:16
guesst
the dualcore arm is maybe more powerful than your phone :)
85
20:16
bootstrap
The one I used before in my camera project was cyclone 3, and only cost $14 (which I considered very high at the time).
86
20:16
bootstrap
The new logic-element cyclone 5 parts are $60 minimum.
87
20:16
guesst
but they are way larger
88
20:16
bootstrap
I don't have a cell phone!
89
20:16
guesst
and less power hungry
90
20:16
bootstrap
Hahaha.
91
20:16
guesst
and faster
92
20:17
bootstrap
I haven't really looked into that. How does it compare with a C8051F120 for example?
93
20:17
bootstrap
I assume it is a 32-bit CPU.
94
20:17
guesst
8051 ~ 8bit?
95
20:17
bootstrap
Yes. 100Hz, generally 1~2 cycles per instruction execution.
96
20:18
guesst
100MIPS stated
97
20:18
guesst
and 8 bit
98
20:18
bootstrap
Okay, so similar, but wider I assume (32-bits, right)?
99
20:18
guesst
a dualcore arm at 1G can do 2000MIPS, 32bit
100
20:18
guesst
so 20x4x more ? :)
101
20:18
bootstrap
The problem is, put one of those uC inside the FPGA, and they want hundreds of dollars for it.
102
20:18
bootstrap
Or at least $100 extra at the very minimum.
103
20:19
guesst
foga is not for mcu replacement
104
20:19
bootstrap
So... unless it is impossible for some reason, putting them on the outside seems wiser.
105
20:19
bootstrap
outside of the FPGA I mean.
106
20:19
guesst
check pm
107
20:19
bootstrap
pm?
108
20:19
guesst
yes, i think that is the way to go
109
20:19
bootstrap
what is pm?
110
20:19
guesst
private message? :)
111
20:20
bootstrap
Oh, where? Is that part of IRC ?
112
20:20
guesst
yes.
113
20:20
guesst
what is your client?
114
20:20
bootstrap
I haven't done much on IRC, so don't know how this works.
115
20:20
guesst
you have channels - groups
116
20:20
bootstrap
XChat on linux.
117
20:20
guesst
many-to-many
118
20:20
guesst
and then there is private, one-on-one
119
20:21
guesst
look at bottom - for channels (#name) or (nickname) for private
120
20:21
bootstrap
Bottom of what? The main window? That's where I'm typing now, and there's nothing here.
121
20:21
guesst
yes
122
20:21
guesst
wait
123
20:21
bootstrap
I'm looking in the menus for "private".
124
20:21
guesst
menu:
125
20:22
guesst
view-channel switcher-tabs
126
20:22
bootstrap
Ah, now I see buttons at the bottom. Click yours?
127
20:22
guesst
yes.
