Hello,

I've found an old satnav (Navman iCN 750) and got to know that it's powered by an Intel PXZ 270 processor (320 MHz). I looked for technical details in the Internet but this CPU seems to not exist. Can someone tell me a few details about this CPU (e.g. cache, performance)? Thanks!

Greetings from Germany!

Intel PXZ 270

■ High-performance processor:

 

—Intel XScale® microarchitecture with

 

Intel® Wireless MMX™ Technology

 

—7 Stage pipeline

 

—32 KB instruction cache

 

—32 KB data cache

 

—2 KB "mini" data cache

 

—Extensive data buffering

 

■ 256 Kbytes of internal SRAM for high

 

speed code or data storage preserved

 

during low-power states

 

■ High-speed baseband processor interface

 

(Mobile Scalable Link)

 

■ Rich serial peripheral set:

 

—AC'97 audio port

 

—I2S audio port

 

—USB Client controller

 

—USB Host controller

 

—USB On-The-Go controller

 

—Three high-speed UARTs (two with

 

hardware flow control)

 

—FIR and SIR infrared communications

 

port

 

■ Hardware debug features — IEEE JTAG

 

interface with boundary scan

 

■ Hardware performance-monitoring

 

features with on-chip trace buffer

 

■ Real-time clock

 

■ Operating-system timers

 

■ LCD Controller

 

■ Universal Subscriber Identity Module

 

interface

 

■ Low power:
