Z,
Try the command:

psrinfo -v

Status of processor 8 as of: 08/29/04 13:39:02
Processor has been on-line since 08/17/2004 14:45:32
The alpha EV6 (21264) processor operates at 524 MHz,
has a cache size of 4194304 bytes,
and has an alpha internal floating point processor.

Re: cache size

the command psrinfo -v give me the amount of L2 cache but i need to know the amount of L1 cache ( on chip cache ).

Re: cache size

the L1 cache depend on the Alpha cpu type, so it may be worth to use the psrinfo output to check the alpha cpu information tables within the internet.
