•

Instruction Set Enhancements - As noted above, there are new instructions such as 32-bit

multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field

multiplication.

•

Exception Handling - Intended to aid the programmer in isolating bugs. The C64x+ CPU is able to

detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and

from system events (such as watchdog time expiration).

•

Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a

basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with

read, write, and execute permissions.

•

Time-Stamp Counter - Primarily targeted for real-time operating system (RTOS) robustness, a

free-running time-stamp counter is implemented in the CPU that is not sensitive to system stalls.
