It has all the advantages of a RISC ( performance: 16070 dhrystones/second on version 2.1, measured on real H/W - not a S/W simulator), with more cost saving features than most other CISCs (dynamic bus sizing, extremely low sensitivity to wait states, minimal code size, etc. etc.....) > >we are interested in something with a development environment that is >mature enough so that we won't be a defacto beta site... > Here I have some more good news. Based on feedback from many happy customers, I can safely say that the NS32GX32 has development tools second to none. These include optimizing compilers, full symbolic debugger (with x-windows interface), HP ISE and HP logic analyzer, both with full dissassembly capability and a realtime trace buffer (which uses on-chip H/W that allows PC trace even when both code and data are in on-chip caches). The development tools run on a variety of hosts: Sun, Vax, and OPUS (Native 32000 development Unix V.3) Jonathan
