Re: Transmeta Crusoe

Transmeta shows TCPA Crusoe

The chip designer Transmeta announced to supply in the second yearly half a version of the Crusoe processor with safety functions after TCPA standard. The functions are integrated thereby directly in the Crusoe TM5800, which makes a separate TCPA chip redundant. The Trusted Computing Platform Alliance is an industrial combination with approximately 180 members, whom a stronger safety device of computers was written by Cryptography hardware on the flags. TCPA is however from some sides as potenzielle incapacitating users under bombardment .

The processor can store now information such as certificates, keys or confidential data within a range, which is not accessible with conventional x86-Befehlen. Besides it is to be offered to the x or Triple-DES a hardware acceleration for coding algorithms as which are used among other things also with procedures such as IP seconds or VPNs. Transmeta defines in addition the command sentence extension TSX (Transmeta Security Extensions), which is to be to each program at the disposal.

Since the Crusoe does not have genuine x86-Kern, but he implements, learns its command sentence by code Morphing on a VLIW core new instructions very fast by updates of the firmware, without an expensive Redesign of the core is necessary. The integration of TCPA succeeds to Transmeta thus faster than others. For example Intel introduces these functions at the earliest with the Prescott core , which is expected approximately for end of the third quarter.

For a completely TCPA secured system all components must along-play. Recently the BIOS manufacturer AMI had presented his TCPA extension , the Transmeta competitors Intel and AMD stands already from the beginning to TCPA.

Transmeta had announced only last week an intensified Embedded commitment and had presented the Crusoe SE, to which now further information is available

Transmeta pokes Trusted Computing plans in eye

Invents own X86 security extensions

DAVID DITZEL AT Transmeta talked about the firm's plans for implementing Palladium in future CPUs in Japan, at the end of November.

See Ditzel Person talks about Transmeta and Palladium.
But now it's official, it seems.

The firm said today it has silicon for a TM 5800 chip with built in embedded security.

Information theft is a major concern to consumers, businesses and governments, said Matthew Perry, the firm's CEO today.

The chips will support the Advanced Encryption Standard but it says that the Trusted Computing Platform Alliance (TCPA) adds cost and increases design complexity and system space requirements.

The Crusoe chips will include an engine, in hardware, for symmetric encryption algorithms including the Data Encryption Standard (DES), DES-X and Triple DES. It's slow in software, but Transmeta reckons it's good in hardware.

The security features will be implemented using Transmeta Security Extensions (TSX) to the X86 instruction set it employs.

So that's one in the eye for the TCPA from Transmeta, we guess.

Ditzel Person talks about Transmeta and Palladium

And reveals more roadmappery
Saturday 30 November 2002, 10:12

THE CHIEF TECHNOLOGY OFFICER OF Transmeta, David Ditzel, has disclosed the firm's plans for implementing Palladium on the firm's future CPUs.

In an interview with Japanese web site PC Watch, Ditzel also revealed details of Transmeta's future roadmaps, confirming some details of its Astro chip, which the firm showed off at Comdex Fall.

Transmeta has scored most of its design wins in Japan, since it first launched its "Crusoe" technology.
Other X86 CPU manufacturers, including AMD and Intel, have already said they will support Palladium in future CPUs.

Ditzel told PC Watch that it would be able to implement Palladium by modifying an intermediate software layer that the CPUs use.

The article suggests that secure features could be built into Transmeta CPUs as early as next year.
