We have learned that laptop brands such as Acer, Lenovo, and Hewlett-Packard have all recently promoted their first-generation ultrabooks in North America.
Sources believe that PC makers dropped the price of ultrabooks in order to empty their inventory to welcome the arrival of the second generation of ultrabooks. These laptop vendors will launch second-generation ultrabooks after Intel released the Ivy Bridge processor in April.
The Acer S3 ultrabook retail price in North America has dropped to 799 US dollars, while Lenovo and HP's ultrabook, the price has also recently dropped by 25% and 21%.
Hewlett-Packard is preparing to introduce the new Ultrabook Envy Spectra 14 laptops in Taiwan this week. Acer and Lenovo's new ultrabooks are all ready for launch in the second quarter.
Although ultrabooks may not reach the Intel target of 40% of total notebook shipments by the end of the year, as more and more new ultrabook products appear in retail channels, the average price of ultrabooks is expected to increase in the second quarter. It will quickly drop from the current 1,000 US dollars to 699-799 US dollars.
984 controllers are available in four generic hardware classes:
Large, rugged, high-performance chassis mount controllers
Rugged, midrange-performance slot mount controllers, which reside in a
primary housing beside 800 Series I/O Modules
Host-based controllers built on various industry-standard computer cards
designed to reside in and execute control logic from a host computer
Low-cost, easy-to-install compact controllers, for applications with less
demanding environmental and performance requirements
The family approach to 984 controller design allows you to make choices based
on controller capacity (the number of discrete and analog/register points available
for application programming, the number of I/O drops it supports), throughput (the
rate at which it solves logic and updates I/O modules), and environmental hardness
(the design standards its hardware implementation must meet).
A major advantage of the family approach to 984 controller design is product
compatibility. Regardless of its computational capacity, performance characteristics,
or hardware implementation, each 984 controller is architecturally consistent
with other 984s.
The 984 instruction set (the functional capabilities of the controller, part of the system
firmware stored in executive PROM) comprises logic functions common to
other 984s. This means that user logic created on a midrange or high-performance
unit such as a 984-685 or a 984B can be relocated to a smaller controller
such as a 984-145 (assuming sufficient memory in the smaller machine) and that
logic created on a smaller controller is upwardly compatible to a larger unit. As
your application requirements increase, it is relatively easy to upgrade your controller
hardware without having to rewrite control logic.
Also, training costs and learning curves can be reduced, since users familiar with
one 984 model automatically have a strong understanding of others.
