From the introduction:

'The functional specification is a detailed specification of the Phoebe (RISC PC II) Project.  Phoebe is a development of the existing RISC PC to incorporate as many new developments in the computer world that have occurred since its launch in 1994 e.g. PCI, E-IDE CODECs and SDRAM etc. It is also intended to exploit the performance of the StrongARM processor as much as possible by increasing the speed of the machine from 16 to 63MHz.  This specification intends to:

a) Define all software and hardware interfaces (for both internal and external developers)
b) Provide some of the information needed for the Programmers Reference Manual, Technical Reference Manual, DVT and PST
c) Define all the environmental and electrical standards
d) Define the scope of the development

This document includes a product overview followed by a section on each functional area.  Where necessary a section will refer to a relevant detailed functional specification. (See section 2.0)
