...S (16 bits multiplied by 65636 there). Afraid not. It really is (PC & ~0xfff) + n * 0x1000. So it does require 12-bit alignment of any code section. Now that you mention the MIPS & RISC-V alternatives, I'm not sure why ARM actually made that choice. It obviously saves you a handful of transistors but I can't quite believe that's all there is to it. Cheers. Tim.

Chip Clock HT Cache Bus Speed --------------------------------------------------------- 5080 3.7 GHz YES 2MB 1066 MHz 5160 3.0 GHz NO 4MB 1333 MHz Does the .7 GHz and HT worth more then 4MB cache and higher bus speed? The application is VoIP so there is not a lot of IO so I would not think Bus Speed would matter. I am finding mixed information on HT, some say it is great, others say it

...lder, and in there, not many LLVM users. There are a lot of A8 devices around with 256KB (or less) of L2 cache (32KB of L1 i-cache), and so code density, if not code size, matters a lot for these. Cache sizes in mobile chips tend to be as small as possible, as it's very hard to turn off those transistors (there are several projects at ARM and elsewhere that I'm aware of in this direction, but I don't know of any in shipping products yet).

Hi everyone. I love JSON and using Prototype has help me reduce the code to handle AJAX responses. But one thing keeps me confused and sometimes even frustrated. I don''t really understand what is going on with the headers, so if someone could take some time to explain what is going on, I (and probably a lot more people) would be very thankful. The thing is this. On my local server (Mac OS

I am located in the UK, and I am using Sipura spa-2000 adapters to connect analog phones to a voip network. The network connects to the PSTN as well via the Sipura spa-3000 adapter. I would like to provide surge protection for the spa-2000 and the spa-3000 adapters. 1. For spa-2000, fxs port: What is the maximum tip-to-ring voltage before damage to the the adapter occurs? 2. For spa-2000,

I haven't tried using -Os/z on any ARM device for the last 3 years, and back then, -Os would break many things. People normally care about code size on Cortex-R/M and ARM9 or older, and in there, not many LLVM users. --renato On 27 February 2013 00:38, Jim Grosbach <grosbach at apple.com> wrote: > I've not run any on non-iOS devices, and haven't looked at GCC since >

...axed due to caching and later flushing large writes (e.g. might happen with logs, if not every line is forcefully synced to storage). Older flash techs also had more write-cycles (by orders of magnitude) than the faster but more fragile current devices which throw smarter caching and more redundant transistors at the problem. So if your Pi's were writing logs "for years" they might just use earlier-generation SD/MMC devices that lacked finesse but were sturdier. Regarding dummy-ups looping, note that NUT v2.8.0 introduced a separation of mode to `dummy-once` (default for `*.dev` files to...

Are you sure about that? In the documentation for the ADRL pseudo it says: "ADRL assembles to two instructions, an ADRP followed by ADD." "ADRL produces position-independent code, because the address is calculated relative to PC." >From this, I'd expect ADRP to simply do Xd <- PC + n*4096, where n is a 20 bit number, just like AUIPC in RISC-V (also a 20 literal

I'm looking at switching from an APC UPS to a different brand after having had my third SU3000RM in a row blow up power transistors. I'm looking at the Cyperpower PR3000LCDRTXL2U. I see the PR3000E and the PR6000LCDRTXL5U listed as supported, but not the PR3000LCDRTXL2U. Howeverit seems likely that if the PR6000LCDRTXL5U is supported, the PR3000LCDRTXL2U ought to work as well. I've been running apcupsd, but if I go...

If you wan't to create a ringtone with makering.pl for firmware 1.0.50, be sure to create it as ring.bin and then rename it to ring1.bin / ring2.bin or ring3.bin. This seems to be the only change between the format from 1.0.4.68. Regards, Maron

...)); c.exp = a.exp; } /* overflow has not even been taken into account here, nor has post-scaling */ So why would anyone use fixed point DSPs? Cost) floating point hardware is more complicated than fixed point, thus more expensive. Energy) more transistors at a given feature size and clock speed require more watts The fixed point chips often supply specialized instructions to aid in floating point emulation. For example, TI 54x and 55x include a single-cycle instruction that gets the number of significant bits in an accumulator. I've programm...

I've updated CentOS 4.0 to 4.1 on several machines (some desktops, some servers). However on my laptop, update is failing with following error just after headers are downloaded: --> Running transaction check --> Processing Dependency: glibc-common = 2.3.4-2 for package: glibc --> Finished Dependency Resolution Error: Missing Dependency: glibc-common = 2.3.4-2 is needed by package

...the concept of extending the pipes any further for performance has been largely broken in the P4, and Intel is actually falling back to its last rev of the i686 original, P3. Multiple, _physical_ cores have been the first step. This is little more than slapping in a second set of all the non-SRAM transistors, plus any additional bridging logic, if necessary. AMD HyperTransport requires none -- as HyperTransport can "tunnel" anything, EV6 memory/addressing, I/O tunnels/bridges, inter-CPU, etc... all "gluelessly." Intel MCH GTL+ cannot, and requires bridges between the "chipse...
