World's top PC maker Hewlett-Packard (HP) is reportedly working on the Android based tablet which is expected to make its debut within this year.

Citing two unnamed sources, ReadWrite claimed that the HP's first Android tablet will be a high-end device powered by the Nvidia's Tegra 4 processor chip.

HP's new tablet will be one of the first devices to feature Nvidia's quad-core processor 'Tegra 4'. Since the new processor chip was launched last month in the international electronics convention CES (Consumer Electronics Show) 2013, other smartphone makers are yet to adopt it.

Sources have also revealed that the HP is also working on an Android based smartphone and the new handset is expected to be launched next year.

HP in its bid to make a stronger comeback in the mobile device arena has chosen to ditch the longtime partner Microsoft to Google. In a show of strained relationship with Microsoft, HP recently introduced a Google OS based 'Pavilion 14 Chromebook' PC.

Two years ago, HP introduced 'HP webOS' based smartphones and tablets, but due to poor sales, the devices were discontinued within eight months of their release.

Even though HP tops the global PC shipments, PC shipments have declined worldwide drastically in the past few years. HP's strategy to re-enter mobile devices is understandable as many technology savvy consumers are inclining towards the lighter and cheaper tablets, and smartphones which are capable of performing same operations of bulky desktops and laptops.
