Description



Features:

• Efficient, object-code compatible, 24-bit DSP56000 family DSP engine
• 47.5 million instructions per second (MIPS) with 21.05 ns instruction cycle at 95 MHz
• Highly parallel instruction set with unique DSP addressing modes
• Two 56-bit accumulators including extension byte
• Parallel 24×24-bit multiply-accumulate in 1 instruction cycle (2 clock cycles)
• Double precision 48×48-bit multiply with 96-bit result in 6 instruction cycles
• 56-bit addition/subtraction in 1 instruction cycle
• Fractional and integer arithmetic with support for multi-precision arithmetic
• Hardware support for block-floating point fast fourier transforms (FFT)
• Hardware nested DO loops
• Zero-overhead fast interrupts (2 instruction cycles)
• PLL-based clocking with a wide range of frequency multiplications (1 to 4096) and power
   saving clock divider (2i: i = 0 to 15), which reduces clock noise
• Four 24-bit internal data buses and three 16-bit internal address buses for simultaneous
   accesses to one program and two data memories


Application

• Minimize the number of pins that are switching.
• Minimize the capacitive load on the pins.
• Connect the unused inputs to pull-up or pull-down resistors.
• Disable unused peripherals.
• Disable unused pin activity.
