To Yann Guidon's questions.
The Power ON Reset clears all all functions in the
SSRAM.
The "Boot Processor" clears the Instruction Memory
and Local Memory (Write Zero's) There is NO Software routine. There is no
SOFTWARE to perform this Function. The Instruction Decoding has NOT
started untill a "RUN" is issued to both
Processors; an Instruction of zero's is a NOP(No Operation)
The Erin36 processor performs
the Boot Process. I guess you could call it a State Machine. It
accumilates one byte at a time (8 Bytes) from Flash Memory then performs a
Write to wherever; then accumulates another 8 Bytes
The Character Generator is
loaded from Flash in same manner as Instruction and Operand Memory (Local
Memory).
The issuing of the "RUN"
is a simple function in Hardware. Once the
Instruction/Operand load is complete
a (counter) the Run FF in the Boot Processor is
set.
The Erin64 IS a General Purpose
CPU; TIPS is my operating system. The F-CPU will require an
Operating
System also. I am not trying to compare the
F-CPU with the ERIN64; however; I have a user slot for each
Terminal.
I am not familar with virtual memoy; however I can
Directly
Address the entire memory with 18 Bits Source and
Destination addresses
More questions??????
