Digital Media Processor
SPRS342A – NOVEMBER 2006 – REVISED MARCH 2007
• Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit
multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field
multiplication.
• Exceptions 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 a 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 which is not sensitive to system stalls.
For more details on the C64x+ CPU and its enhancements over the C64x architecture, see the following
