![]() My current project with the Prime is to investigate the possibility of better integration between programs and external sensor inputs. If anyone is interested, I can also post my tear-down of the classroom connectivity kit and the StreamSmart 410. ![]() I did a HP Prime tear-down and posted hi-rez photos of all the interior parts. Here is the link to "Prime Hardware" thread I started. (02-08-2015 07:50 PM)dbbotkin Wrote: Thanks for the creative work on the JTAG interface and alternate Linux system. Potentially, yes, though pursuing the baby steps approach, which I prototyped with my crappy armfir.elf PoC which doesn't cooperate with the undocumented host OS, would be an interesting first milestone. ![]() Quote:so are you proposing to replace the entire s/w stack? However, the way devices (component motherboards, USB, etc.) are connected to the SoC is undocumented (that is a prerequisite for porting Linux), and the software is basically completely undocumented, save for a subset of the first 4 KB of BXCBOOT0.BIN (the early boot code), posted some day by an anonymous user, over a year ago. The S3C2416 SoC is indeed well documented (a year ago, I gathered links on the TI-Planet hpwiki) and supported by Linux. Quote:I think the h/w and core s/w components (low-level O/S, Prime applications, etc) have been documented, However, the Prime only has half of the CX's RAM, so some workloads would run worse on the Prime than they do on the Nspire CX. On raw CPU power, Linux would run faster on the Prime than on the Nspire CX, given that the Prime's CPU is more than twice faster than the Nspire CX's. That's one of the potential applications of reverse-engineering the Prime, indeed. Of course, you may choose to adjust some factors up or down to suit your own situation, but I find the numbers to be pretty accurate based on my own IT experience.ĭon't guess about what your current computers cost or what new computers could save your company - calculate the value for yourself! I think you'll find this tool is a great place to start.Quote:Is the plan to create alternate s/w to run within the current h/w case? This cost is then offset by labor savings using your users' cost numbers. Next, move on to the power management matrix.įinally, enter the user cost metrics of your workers.Īfter you enter these numbers, the tool computes a total cost profile, including software/hardware deployment and energy savings. Recently, I began poking around the ownership cost estimator on the Intel web site, and have found it to be a powerful and flexible tool that can help with this task.īegin your calculations by entering the computer topology of your company. I've often done basic cost analyses on these types of issues by creating my own spreadsheets, but have always felt my numbers were suspect because I could never fully quantify the IT costs related to a machine's lifetime. ![]() If you've ever wanted to compute the cost of owning, powering, or servicing computers over a multiyear lifespan, you've no doubt thought about how much information you'd need to undertake such a task - and possibly felt daunted by it.
