The TMS320C5x generation of the Texas Instruments (TI™) TMS320 digital signal processors (DSPs) is fabricated with static CMOS integrated circuit technology; the architectural design is based upon that of an earlier TI DSP, the TMS320C25. The combination of advanced Harvard architecture, on-chip peripherals, on-chip memory, and a highly specialized instruction set is the basis of the operational flexibility and speed of the "C5x devices. They execute up to 50 million instructions per second (MIPS).
●The "C5x devices offer these advantages:
● Enhanced TMS320 architectural design for increased performance and versatility
● Modular architectural design for fast development of spin-off devices
● Advanced integrated-circuit processing technology for increased performance
● Upward-compatible source code (source code for "C1x and "C2x DSPs is upward compatible with "C5x DSPs.)
● Enhanced TMS320 instruction set for faster algorithms and for optimized high-level language operation
● New static-design techniques for minimizing power consumption and maximizing radiation tolerance
●Table 1 provides a comparison of the devices in the "C5x generation. It shows the capacity of on-chip RAM and ROM memories, number of serial and parallel I/O ports, execution time of one machine cycle, and type of package with total pin count.
