Assignee:
Dallas Semiconductor Corporation - Dallas TX
International Classification:
G06F 1130
US Classification:
713200
Abstract:
An electronic module having at least a microprocessor and co-processor on a single integrated circuit. The electronic module can be contained in a small housing. The electronic module provides secure bidirectional data communication via a data bus. The electronic module may include an integrated circuit comprising a microprocessor, and a co-processor adapted to handle 1,024-bit modulo mathematics primarily aimed at RSA calculations. The electronic module is preferably contained in a small token sized metallic container and will preferably communicate via a single wire data bus which uses a one-wire protocol.

US Patent:
58623540, Jan 19, 1999
Filed:
Mar 5, 1996
Appl. No.:
8/611035
Inventors:
Andreas Curiger - Dallas TX
Wendell L. Little - Denton TX
Matthew K. Adams - Dallas TX
Assignee:
Dallas Semiconductor Corporation - Dallas TX
International Classification:
G06F 1300
US Classification:
395290
Abstract:
A processor system is disclosed wherein said processor system is adapted to communicate over at least one one-wire network utilizing one-wire communications protocol. For the embodiment of the invention in which the processor system acts as a network master, the processor system includes a master UART especially configured to control communications over such network according to one-wire protocol. For the embodiment of the invention in which the processor communicates over two one-wire networks, the processor system includes a first UART which acts as a slave and a second UART which acts as a master.

US Patent:
63306689, Dec 11, 2001
Filed:
Aug 14, 1998
Appl. No.:
9/133946
Inventors:
Andreas Curiger - Dallas TX
Wendell L. Little - late of Denton TX
Assignee:
Dallas Semiconductor Corporation - Dallas TX
International Classification:
G06F 1130
US Classification:
713 1
Abstract:
An integrated circuit, such as a microprocessor, which incorporates hardware mechanisms to prevent the circuitry from operating outside the proper bounds of design. The hardware circuitry prevents the microprocessor circuitry from being forced to operate at clock speeds that are greater than it is designed for, from operating at temperatures above or below that which it is designed for, and from being forced to operate at voltages that are above or below voltages that the microprocessor is designed to operate at.

US Patent:
6064740, May 16, 2000
Filed:
Nov 12, 1997
Appl. No.:
8/969144
Inventors:
Andreas Curiger - Dallas TX
Wendell Little - Denton TX
International Classification:
H04L 900
US Classification:
380265
Abstract:
Circuitry which performs modular mathematics to solve the equation C=M. sup. k mod n and n is performed in a manner to mask the exponent k's signature from timing or power monitoring attacks. The modular exponentation function is performed in a normalized manner such that binary ones and zeros in the exponent are calculated by being modulo-squared and modulo-multiplied.
