I'm fed up with Acorn being ignored. Okay... (Since I'm not on talking terms with Maplin, I'll post here instead.) Architecture 32-bit RISC Age of architecture 9 years Primary operating system RISC OS/Newt OS/3DO/RISC iX/Helios etc. etc. Transistor count 578977 Core logic transistor count 35610 On-chip cache size 8K Die size 68.51mm2 Heat dissipation at 33MHz 611mW Performance: integer at 33MHz 52050 dhrystone 2.1 (SPECint N/A) floating point at 66MHz Not applicable Estimated manufacturing cost $20-40 (very rough estimate) Maximum instructions per cycle 1 General-purpose registers 15 Floating-point registers none Follow-on processors ARM7xx family, ARM8xx family, ... The cost-estimate is just that - I have absolutely NO idea what anyone is going to charge for the ARM700. Floating point is available via. the FPA series of floating-point accelerators, which offers ~5MFLOPS @ 20MHz with extremely low power consumption.
