SUMMARY
High performance signal processor for communications,
graphics, and imaging applications
Super Harvard Architecture
Four independent buses for dual data fetch, instruction
fetch, and nonintrusive I/O
32-bit IEEE floating-point computation units—multiplier,
ALU, and shifter
Dual-ported on-chip SRAM and integrated I/O peripherals—a
complete system-on-a-chip
Integrated multiprocessing features
KEY FEATURES—PROCESSOR CORE
50 MIPS, 20 ns instruction rate, single-cycle instruction
execution
120 MFLOPS peak, 80 MFLOPS sustained performance
Dual data address generators with modulo and bit-reverse
addressing
Efficient program sequencing with zero-overhead looping:
single-cycle loop setup
IEEE JTAG Standard 1149.1 test access port and on-chip
emulation
32-bit single-precision and 40-bit extended-precision IEEE
floating-point data formats or 32-bit fixed-point data
format
240-lead MQFP package, thermally enhanced MQFP, 225-ball
plastic ball grid array (PBGA)
Lead (Pb) free packages. For more information, see Ordering
