Tegra from Nvidia and OMAP from Texas Instruments: The Details

Yesterday, I talked about 'Single Core' processors. So, as I said, people started integrating dual core processors on a single chip. These chips are also called Multi-Processor System on Chips (MPSoC). Here are a few examples of manufacturers and their respective dual-core processor chips.

Nvidia

• Nvidia currently manufactures the 'Tegra 2' chip. As you all might be knowing, Tegra 2 is a dual core processor System on Chip (SoC). This chip contains various components like the CPU or microprocessor (core), the CPU Instruction Set, the Memory Controller and the GPU (Graphics Processing Unit). The CPU or the microprocessor is not manufactured by Nvidia itself but sourced from another company called ARM. Inside the Tegra 2 chip, there are 2 ARM Cortex - A9 processors (dual-core) and thereby the Tegra 2 derives it's name.
• Some of the famous smartphone devices which sport the 'Tegra 2' chip are 'LG Optimus 2X', 'Motorola Atrix', 'Samsung Galaxy R' and tablets such as 'Motorola XOOM', 'LG Optimus Pad' and 'Acer Iconia Tab A100 and A500' also sport the same chip. Note that the Tegra 2 chip in the above listed devices runs at a frequency of 1 Ghz. 
• There is another variant of the 'Tegra 2' processor which is clocked at a speed of 1.2 Ghz and runs inside the following device: 'Fusion Garage Grid 10' 

Texas Instruments

• Texas Instruments manufactures the 'OMAP' (Open Multimedia Application Platform) chip. The 4th generation of OMAP chips i.e. OMAP 4430, OMAP 4460 and OMAP 4470 are dual core processor System on Chips (SoC). This chip also contains various components that are necessary for the 'System on Chip' to function like the CPU or microprocessor (core), the CPU Instruction Set, the Memory Controller and the GPU (Graphics Processing Unit). As in the case of Nvidia, the CPU or the microprocessor is sourced from ARM. Inside the OMAP 4th generation chips, there are 2 ARM Cortex - A9 processors (dual-core).
• There are a few differences that separate the 3 OMAP dual-core processing System on Chips. As I have already conveyed, each System on Chip also contains a GPU in addition to the CPU, the GPU in OMAP 4430 is clocked at  304 Mhz, whereas the GPU in OMAP 4460 is clocked at 384 Mhz. Additionally, the OMAP 4430 processors are clocked between 1 and 1.2 Ghz, whereas the OMAP 4460 processors are clocked between 1.2 and 1.5 Ghz. By this it is apparent that the OMAP 4460 is more powerful than the OMAP 4430. The OMAP 4470  will be explored later along with the latest Nvidia Tegra 3 quad core chip in another post.
• Some of the famous smartphone devices which sport the 'OMAP 4th generation' chips are 'Motorola Droid Razr' and 'Samsung Galaxy Nexus'. Inside the Droid Razr, OMAP 4430 is residing with a clocked speed of 1.2 Ghz whereas in the Galaxy Nexus, OMAP 4460 is residing with a clocked speed of 1.2 Ghz.

So, that's it for today. Samsung's own 'EXYNOS' chip and Qualcomm's 'SNAPDRAGON' chip will be explained in the next post. Stay tuned..!!
