No one is advocating eliminating modulo arithmetic - the trapping instructions would be different ops, just like on architectures that already implement this such as MIPS.

Zero chance the buyer and/or house will fail to qualify for a mortgage. Also gives the seller more leverage in not having to fix issues not required by law.

In software terms, that's more difficult than adding support for new HTML extensions given java byte code for a web browser. No one makes modifications that could affect instruction timings (which is a very fundamental aspect of a core

Intel actually provides better documentation on its CPU pipelines than ARM does, especially for anything more advanced than the Cortex-A9. Then with Cortex-A5 and A7 you don't even get instruction timings. Cortex-A15 you get nothing

Cache coherency isn't something that average app developers have had to worry about since forever - the only place I can think of most developers might encounter issues is with GPU programming, but graphics APIs tend to deal with coher

They're probably referring to the bug/"feature" in Linux's implementation, which will happily return data before the system has enough entropy, instead of the sane behavior of blocking on only the first calls to i

It wasn't really ever in the running for phones/tablets; there were some cheap no-name Chinese devices using MIPS early on but now they all use Rockchip or Mediatek SoCs. Imagination did buy MIPS with the stated goal of pushing in

JPEG-XR has (optional) lapping. But lapping has the problem that you can't do spatial intra prediction, which is significantly more valuable. And no one figured out how to make frequency-domain intra prediction as good until Daala. Plu

Do note that his "JPEG" is really JPEG with a PAQ entropy coder, which is actually a new format and not at all decodable by a JPEG decoder. He does no tests on baseline JPEG. But it's useful to point out that a lot of new ove

Pretty well if it's a regular layout, depending on algorithm, since almost every successive pixel is different from the last by exactly one level in one channel.

I was thinking more along the lines of if writing for sh and make were less painful, then fewer developers would accept using such awful build systems instead. Autotools included.

by brigade 13y ago
It's also kind of amazing how terrible most of the replacements people developed are. Some are significntly worse than autotools, which is no mean feat. I blame make's awful syntax.

Freescale and TI tend to be good about providing heaps of documentation without requiring any NDA. Unfortunately, they're pretty alone in that regard.

Even without superscalar execution it'd still help, since no sane architecture has floating-point arithmetic with an effective latency of 1 cycle. Current Intel cores have a latency of 3 cycles for FP add, and 4 cycles for FP multiply.

Intel released Atom not 6 years ago, and is still selling Bonnell-derived CPUs to this day... Cortex-A7 and A53 are in-order as well, and are/will be quite common among low-end Chinese smartphones and tablets.

Well, Intel vaguely sells a 4-core Xeon at 1.8/2.8 GHz with 25 W TDP [1], then between the hyperthreading and higher IPC you've mostly made up for the fewer cores relative to this ARM part. [1] http://ark.intel.com&#x2F

No it couldn't, because the compiler cannot make assumptions about the heap allocator beyond what the C spec says, which is basically just the function signatures. An allocator that never frees memory is entirely within the C spec and

One problem is that category 1 HDMI cables are only specified to support 1080i signals. They aren't guaranteed to support 1080p60, and a number of cables (especially no-name chinese cables or longer runs) are only tested to this spec,

Yes, all non-IPS laptop displays for instance. They're actually 6 bits and use temporal dithering to display 8-bit color. And indeed, most "10-bit" panels are 8-bit with FRC.

Get a better cable, or don't bend your current cable so much.

Nope on Connectix VGS not emulating the CPU - PSX and PS2 both used MIPS CPUs, vs. PowerPC in Mac. It very much was the exact same thing as PCSX or derivates. The only platform a PSX emulator might have not done full dynarec/interpreta

PPC OS X apps didn't need any low-level system emulation; they could only talk to hardware via the kernel, and they could only talk to the kernel via system libraries. So at kernel boundaries you could simply translate the PPC system c
