With a 100-ns instruction cycle time and an  
innovative memory configuration, the ’320P25  
performs operations necessary for many real-time  
digital signal processing algorithms. Since most  
instructions require only one cycle, the  
TMS320P25 is capable of executing ten million  
instructions per second. On-chip programmable  
data/program RAM of 544 words of 16 bits,  
on-chip program EPROM of 4K words (one-time  
programmable memory), direct addressing of up
