memory allocation package wanted

[ned]

I'm developing a device driver that requires varying amounts of
shared memory to be dynamically allocated and deallocated.

I'm looking for a public domain memory allocation package which
is functionally equivalent to malloc, but is designed so that
buffer information (pointers, flags, etc.) are maintained in
an area that is separate from the arena itself (i.e. does not
use a linked list as malloc classic does).

My particular application requires that memory be allocated at
interrupt level, so critical sections of code need to be
fast and few.

Can anyone help?

Thanks.
