Apple A5 processor

Apple A5 processor is a new processor for apple products designed by Apple and manufactured by Samsung. Apple A 5 is expected to be the core processing unit of upcoming apple iphone 5.

Apple A5 uses package-on-package technology, which is an integrated circuit packaging technique that combines discrete logic and memory ball grid array packages.
These packages are arranged one above the other and a standard interface routes the signals in between them.
The main benefit of package-on-package technology is, motherboard space savings and also the RAM device is not coupled with the logic device.

The A5 processor contains ARM Cortex A9 CPU with NEON SMD accelerator and dual core POWER VR SGX543MP2 GPU (Graphics Processing Unit), which can move 35 million polygons per second at 200 MHz. The processor powers DDR2 (double data rate) and 512 MB RAM (memory capacity). Neon technology is a 64+128 bit SIMD (Single Instruction Multiple Data), which is an instruction set that is used in the ARM architecture of A5. This instruction set provides high standard acceleration for signal processing applications. A5 is a system-on-a-chip based technology and it is a single integrated circuit chip that contains all types of signals on a single chip substrate.
