Motorola decided to change some of the peripheral units on the chip, hence the delay. Don't expect more than 333 MHz, maybe 266 MHz for the first silicon. V4e still won't be able to properly trap out *all* 68k instructions that are not equivalently implemented. But it is much better than all previous versions, and the number of oddities is so small that I guess only handwritten assembler code will be affected. Can you point where Motorola publicised full compatibility with the 68K? All the best Peter

Re: [ql-developers] K68 Core
SNIP StrongARM? IMHO not nearlz powerfull enough for this and not so easily obtainable. Only Intel makes those 200+ MHz chips, others like Atmel etc make much slower units
Re: [ql-developers] K68 Core
Yeah. I have seen it. A couple of questions/remarks: -is this legal ? I remember contacting MC regarding making MC68000 in FPGA some years ago and their answer was a firm NO- they would not allow me to use 68000 ISA. - there is a related project somewhere, called IIRC V68000, which has the same instruction set as 68000 but it isn't binary compatible. -even if guy gets his off the ground and even if he uses the newest Spartan-3 FPGA, he will never reach the speeds even comparable with Coldfire 5307, let alone 5407 or the newest, yet-to-be-out 5471 or 5472. branko - Original Message - From: Phoebus Dokos [EMAIL PROTECTED] To: QL Developers Mailing List [EMAIL PROTECTED] Sent: Sunday, July 13, 2003 10:54 PM Subject: [ql-developers] K68 Core Anybody seen this?

Re: [ql-developers] K68 Core
I didn't know anything about the price. I plan to finally buid a decent homebrew machine and I had my eyes on 5407.Nice machine, but nothing really spectacular and no MMU. Just the other day I have posted the question to their support service, when will the 5471 be available, since it has MMU also (besides having enhanced core etc). I have got no answer still... But while searching around, I have stumbled on to superb alternative: MIPS. Decent core in several versions, supoported by several sources in all flavours and main sources seem to be hardworking, modest japanese guys instead of selfimportant pricks at MC. Check out NEC's offer and even more importantly PMC-Sierra. These guys rock. Latest incarnation is a 64 bit machine, has a decent FPU, 256 Kb of L2 cache, works on up to 1 GHz AND IS STILL IN QFP ! Oh, and it churns some 3.5W typicaly ! This thing would run Linux and emulate QL at the same time, even while powered down ;o) They have also the faster models, but those are in BGA packing :o) I'm thinking about using this one and also having smaller, slower, 32 bit version with FLASH at hand for those microcontroller jobs, where speed is not so critical, but space, cost and money are... Also, Hitachi makes nice things, but those are AFAIK not MIPS-compatible Branko - Original Message - From: Phoebus Dokos [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, July 14, 2003 12:09 AM Subject: Re: [ql-developers] K68 Core On Sun, 13 Jul 2003 23:50:51 +0200, BRANE [EMAIL PROTECTED] wrote: Yeah.
