From our friend Keith Wooten on USENET. Lively discussion on what would be the most cost effective and efficient solution for running java, ie; picoJava, strongArm, or PSC10000, the strongARM representing a general purpose processor needing a JIT: Re: Sun opens picoJava and SPARC design sources Author: Keith Wootten <Keith@wootten.demon.co.uk> Date: 1999/03/05 Forum: comp.lang.java.machine sponsored by: more headers author posting history -------------------------------------------------------------------------------- In article <7bmmnn$5e3@edrn.newsguy.com>, steve@blighty.com writes >In article <36e1c4b5.73617746@news.bctel.ca>, roedy@mindprod.com says... >> >>On 4 Mar 1999 14:28:22 GMT, lindahl@pbm.com (Greg Lindahl) wrote: >> >>> >>>Yes.

Only if you ignore what seems to be the best solution, that is, a general purpose stack processor optimised for Java. Cheers -- Keith Wootten
