12 Questions To... Natami Team - Part 1
12 questions to... Natami Team - part 1 Banter (c) Polski Portal Amigowy (www.ppa.pl) Today I will tell you about something unique. I will present you the latest 68k CPU! You may wonder... What actually is N68050? The N68050 (N050) is a new 68k family processor developed by the Natami Team. It runs inside the FPGA together with the Natami chipset. The 050 is the first revision of our 68k CPU architecture. Further on, we will extend the architecture to the N68050E and later the N68070 specification. The N68050 softcore will be the default CPU of the Natami system. But if the user wants to, he could also get a separate CPU card with a physical 68060 for his Natami system, connected to the mainboard over the SyncZorro bus. The development history of the N68050 core. One could say it started in 1998, when Gunnar tried to write his first 68k softcore. But FPGAs were unfortunately too small to accomplish this task back then. The actual development of the Natami softcore started two years ago, after we dismissed Coldfire as a possible CPU for the Natami. Coldfire was interesting, but our testing and estimates showed us that solving it with our own softcore is even better. The first "N68070" softcore design idea was similar to a crossbreed of 68000 and Coldfire. Our first concept was to use a pipeline similar to the Coldfire V3 pipeline. To improve performance we changed this and reworked the pipeline to be longer. Our goal for the softcore was to reach a higher clockrate and to be in all regards better than the original Motorola 68060 clocked at the same speed. -

PART I Janusz Zalewski Dept. of Software Engineering, Florida Gulf Coast University Fort Myers, FL 33965, USA [email protected], http://www.fgcu.edu/zalewski/ Abstract: The objective of this paper is to present a historical overview of design choices for data acquisition and control systems, from the first developments in CAMAC, through the evolution of their designs operating in VMEbus, Firewire and USB, to the latest developments concerning distributed systems using, in particular, wireless protocols and time-triggered architecture. First part of the overview is focused on connectivity aspects, including buses and interconnects, as well as their standardization. More sophisticated designs and a number of challenges are addressed in the second part, among them: bus performance, bus safety and security, and others.

Architectural Support for Real-Time Computing Using Generalized Rate Monotonic Theory

SATHAYE** Abstract The rate monotonic theory and its generalizations have been adopted by national high tech- nology projects such as the Space Station and has recently been supported by major open stand- ards such as the IEEE Futurebus+ and POSIX. 4. In this paper, we focus on the architectural support necessary for scheduling activities using the generalized rate monotonic theory. We briefly review the theory and provide an application example. Finally we describe the architec- tural requirements for the use of the theory.
