Mentre il 440EP arriva SOLO fino a 667MHZ e stop... ...il 460EX invece PARTE da 667MHz e arriva fino a 1.2 GHz di clock...

AH! Se ACube decidesse si implementarlo su una ipotetica Samantha 2!

Immaginatevi quindi Samantha che rulla a 1.2 GHz...



E il 460EX ha inoltre tutte queste belle feature...
DDR2, PCI-Express, PCI, Gigabit Ethernet, TCP/IP Acceleration Hardware. GPIO
USB 2.0, PCI-Express, SATA, Gigabit Ethernet, security, NAND Flash interfaces and low power dissipation, the PowerPC 460EX embedded processor is ideally suited to a wide range of high-performance applications, including imaging, industrial control and networking.

Ora mettiamoci vicino qualcosa di più!
Tutto questo, magari immaginatelo che funzioni su una piastra madre Samantha 2 di 17x17 cm con l'AMCC 460EX magari affiancato da una FPGA più potente, che sia capace di emulare fino al chipset AGA di Amiga...
Ed immaginatevi sempre sulla piastra madre un VERO Coprocessore, che poi è in realtà anch'esso un PPC operante a soli 165 MHz...
L'IBM IBM STB034xx (ci sono processori STB0321X, STB0341X, ecc...)
Che cosa è questo processore?
E'un PowerPC dedicato ad essere inserito nei Set Top Box multimediali (TV, videoregistratori digitali, ecc...)
http://www.linuxdevices.com/products/PD4758195353.html
Quali feature ha?
- Integrated PowerPC 405 processor
- MPEG-2 audio/video decoder with five on-screen display video planes
- Dolby Digital audio decoder option (IBM STB0321x and STB0341x only)
- MPEG-2 transport demultiplexer
- On-screen display controller
- NTSC/PAL digital encoder
- IDE hard drive interface
- Smart card, parallel, and serial I/O interfaces
- 2.5W typical power dissapation
Non male vero?
A questo punto resta solo da decidere la componente grafica ATI(?) per il 3D e per risoluzioni oltre la normale TV digitale terrestre...
Con 3 Chip messi in croce su una piastra madre minuscola avremmo il VERO Amiga del ventunesimo secolo, capace di gestire tutte le periferiche moderne USB 2.0, SATA e PCI-Express e capce di emulare al massimo i vecchi Amiga, e può anche catturare TV digitale, oppure permettere di vedere la grafica Amiga di una volta, emulata su TV digitale, col suono FULL DOLBY SURROUND...
Un sogno?
No un piccolo consiglio da dare ad ACube System...
Ragazzi di ACube?
Incominciate a prendere dei chip campione e fate delle prove di fattibilità...
