PXA320 Processor Block Diagram

Codenamed Monahan P, the PXA320 is the fastest processor in the PXA3xx family and is designed to power high-end handheld devices like Smartphones, PDAs and even UMPCs.

Built on a 90nm process technology, it has been demonstrated to be capable of running at 1.2GHz at 1.1V. However, Marvell will only be offering this processor in volume with the clock speed of 806MHz.

The processor has a 64KB L1 cache, a 256KB L2 cache and a 32-bit DDR memory interface. The memory controller supports DDR memory of up to 260MHz.

It also comes with a 768KB frame buffer for VGA-quality graphics, a 2D graphics accelerator and hardware video acceleration.

Thanks to its Intel heritage, the PXA320 will feature some key Intel technologies. The first is the Wireless Intel SpeedStep technology which improves the processor's power efficiency to deliver a longer battery life. It also supports Intel's Wireless MMX 2 technology as well as Intel's Enhanced Quick Capture technology which supports camera sensors up to 5 megapixels.

This value-level processor, codenamed Monahan L, is targeted at 2G, 2.5G phones, low-end Smartphones and handheld GPS devices.

Built on a 90nm process technology, it is capable of running at up to 624MHz. This processor has a 64KB L1 cache, a 256KB L2 cache and a 16-bit DDR memory interface.

Because it's targeted at devices with QVGA displays, it will only come with a 256KB frame buffer. It will have a 2D graphics accelerator but no hardware video acceleration.

The PXA320 will feature key Intel technologies like the Wireless Intel SpeedStep technology and Wireless MMX 2 technology but it won't support Intel's Enhanced Quick Capture technology.
