what is SDLC?
-
been browsing for new jobs lately... in Australia... what do they mean by "Full SDLC experience?" also, what is the formal definition of Embedded real time systems? I've done heapes of real-time data communication thru sensors and wrote corresponding programs to run them. Would this count as embedded real time experience? many thanks

From Clickety[^]... I think the IEEE definition (supplied by Douglass Locke) is a good one, and a clear one. Namely: "a real-time system is a system whose correctness includes its response time as well as its functional correctness." The system doesn't just run software to plough through the process; it needs to do it in a timely manner. So, real-time systems care about timeliness, but just how timely isn't clear until you add a modifier to "real-time". In other words, real-time is very much a gray region. "Response to what?" To "events", which are either external events, communicated to the system via its input/output interfaces (which include things like Ethernet as well as audio, keyboard, or mouse input), or to timer-triggered events within the system itself.

In my day it meant "Synchronous Data Link Control". This protocol was established by IBM (aka "God") to allow the "unwashed" (aka "the rest of us") to communicate with "God". Much like the "Tower of Babel". Only harder to understand.:rolleyes: Seriously, if it is really "Synchronous Data Link Control" it's really no more than ODBC at an AS/400 level. Very simple. Cheers.

LOL!! I thought it was "Synchronous Data Link Control" too. I have no earthly idea what these other guys are talking about :) By the way, I also "grew up" worshiping the tower of blue - AS/400, S/38, OS/2, SNA, APPPC, LU6.2, etc. etc. By the way, SDLC has no comparison to ODBC. ODBC is a generic SQL-like interface to data stores while SDLC is a protocol describing synchronous communciations between devices. Cheers, Tom Archer "Use what talents you possess.

A 'rule of thumb' for embedded systems: 1. No hard drive 2. No video 3. Keep reprogramming the flash 4. Hope you don't run out of RAM 'cos you only have so much ! Elaine :rose: The tigress is here :-D

One of my group's tasks once upon a time was to program a self-test routine for a handheld SAM popular with insurgent groups. It only had 512 bytes of RAM. Many a night was lost trying to find some clever, yet efficient way to save a single byte of memory. Will Build Nuclear Missile For Food - No Target Too Small

If they are speaking of embedded systems, SDLC in this case is very likely Synchronous Data Link Control. You must have knowledge of, and experience working with, the SDLC protocol. Chris Richardson
