The CoCo 5 was imagined to
be controlled by 4 - 6309 CPU's and a GPU , If it ever gets implemented it
will most likely be via FPGA.
The CPU#1 refers to a 6309 core which may operate in one of two
modes.
When runing as the System
Hardware Coordinator CPU#1provides Hardware Assignment and
Coordination functions for the entire system this allows CPU's #2 and 3 to
effectively share the available hardware with no special software each
"thinking" unless programed otherwise that it is the only CoCo on the
system.
This CPU may run at any multiple of 0.894 MHz up to 7.152 MHz and will
switch speed as appropriate to the process it is runing. In this mode CPU
#1 will address memory beyond 64K by one of two methods STANDARD
or HWAM mode.
The main functions of CPU#1 in System Hardware Coordinator mode are to:
CoCo Blue | Notes |
