description
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
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
