A computer system that controls much of the flow of electricity across California was under siege from hackers for at least 17 days during the height of the state’s ongoing power crisis, the Los Angeles Times reported .The cyber attack, while apparently limited, exposed security lapses in the system that the California Independent Systems Operator (Cal-ISO) uses to oversee most of the state’s massive electricity transmission grid and connect to the grid for the western USA. Analog unveils chips US chipmaker Analog Devices Inc unveiled a new line of digital signal processors (DSPs) that can enhance video and other functions on devices such as handheld computers. The Blackfin chips, using an architecture developed jointly with Intel Corp, incorporate a programmer-friendly design to facilitate speedy development of software and hardware, including applications that will be key to the success of next-generation wireless devices. Analog Devices also announced a power management chip that would cut the DSP’s power consumption by more than 60 percent, by adjusting the voltage and frequency to minimise the amount of energy used for any given processing task. — Reuters |
