80960SA
The 80960SA provides two hardware breakpoint
registers
on-chip
which,
by
using
a
special
command, can be set to any value. When the
instruction pointer matches either breakpoint register
value, the breakpoint handling routine is automati-
cally called.
The 80960SA also provides software breakpoints
through the use of two instructions: MARK and
FMARK. These can be placed at any point in a
program and cause the processor to halt execution
at that point and call the breakpoint handling routine.
The breakpoint mechanism is easy to use and
provides a powerful debugging tool.
Tracing is available for instructions (single step
execution), calls and returns and branching. Each
trace type may be enabled separately by a special
debug instruction. In each case, the 80960SA
executes the instruction first and then calls a trace
handling routine (usually part of a software debug
monitor). Further program execution is halted until
the routine completes, at which time execution
resumes at the next instruction. The 80960SA’s
tracing mechanisms, implemented completely in
hardware, greatly simplify the task of software test
and debug.
1.1.10 Fault Detection
The 80960SA has an automatic mechanism to
handle
faults.
Fault
types
include
trace
and
arithmetic faults. When the processor detects a fault,
it automatically calls the appropriate fault handling
routine and saves the current instruction pointer and
necessary
state
information
to
make
efficient
recovery possible. Like interrupt handling routines,
fault handling routines are usually written to meet the
needs of specific applications and are often included
as part of the operating system or kernel.
For each of the fault types, there are numerous
subtypes that provide specific information about a
fault. The fault handler can use this specific infor-
mation to respond correctly to the fault.
1.1.11 Built-in Testability
Upon reset, the 80960SA automatically conducts an
exhaustive internal test of its major blocks of logic.
Then, before executing its first instruction, it does a
zero check sum on the first eight words in memory to
ensure that the memory image was programmed
correctly. If a problem is discovered at any point
during the self-test, the 80960SA asserts its FAIL pin
and will not begin program execution. Self test takes
approximately 24,000 cycles to complete.
System manufacturers can use the 80960SA’s self-
test feature during incoming parts inspection. No
special diagnostic programs need to be written. The
test is both thorough and fast. The self-test capability
helps ensure that defective parts are discovered
before systems are shipped and, once in the field,
the self-test makes it easier to distinguish between
problems caused by processor failure and problems
resulting from other causes.
1.1.12 CHMOS
The 80960SA is fabricated using Intel’s CHMOS IV
(Complementary High Speed Metal Oxide Semicon-
ductor) process. The 80960SA is available at 10 and
16 MHz in the QFP package and at 10, 16 and 20
MHz in the PLCC package.
