Programming the bear And let's not neglect to mention the tools needed to develop battle-hard- ened applications. One big fear that took shape last year and lingers on is concern about tool availability. A year ago, th e embedded community began to worry that fewer development tools would be avai lable for each chip on the market. That con cern was h e ightened by Motorola's acquisition of software- tools vendor Metrowerks. Those concerns have not been borne out. Rather, there may be cause for optimism instead. A case in point is In-Circuit Emulators tl1e Sta.rCore DSP architecture, which comes out of the eponymous company formed as an alliance between Lucent Technologies and Motorola. Sta.rCore has actively financed the development of compilers and toolsets from Green Hills Software. The latter firm says the product is about to ship. Meanwhile, Tasking says they are going to offer their own, robust set of tools for StarCore, eve n though Motorola hasn 't officially taken them under its wing. Tasking points to its 15 years of experience with DSPs as the reason it believes it will come up with a winning toolsuite. So here is an example of an embedded part (albeit a DSP) that is garnering more tools support, not less. The same can be said on the real- time-operating-system front, where a host of next-generation RTOSes are being aggressively served up by the likes of Wind River, Enea OS, LynuxWorks, and others. Nevertheless, it behooves the Preserve your investment in time and capital with universal emulators from iSYSTEM. A complete line, from low-cost BDM/JTAG to high-end full-function ICEs.
