Instruction Set Summary
The 80960Jx adds several new instructions to the i960 core architecture. The new instructions are:
Table 1 identifies the instructions that the 80960Jx supports. Refer to the i960
Developer’s Manual (272483) for a detailed description of each instruction.
Faults and Debugging
The 80960Jx employs a comprehensive fault model. The processor responds to faults by making
implicit calls to a fault handling routine. Specific information collected for each fault allows the
fault handler to diagnose exceptions and recover appropriately.
The processor also has built-in debug capabilities. In software, the 80960Jx may be configured to
detect as many as seven different trace event types. Alternatively, mark and fmark instructions
can generate trace events explicitly in the instruction stream. Hardware breakpoint registers are
also available to trap on execution and data addresses.
Low Power Operation
Intel fabricates the 80960Jx using an advanced sub-micron manufacturing process. The processor’s
sub-micron topology provides the circuit density for optimal cache size and high operating speeds
while dissipating modest power. The processor also uses dynamic power management to turn off
clocks to unused circuits.
Users may program the 80960Jx to enter Halt mode for maximum power savings. In Halt mode,
the processor core stops completely while the integrated peripherals continue to function, reducing
overall power requirements up to 90 percent. Processor execution resumes from internally or
externally generated interrupts.
