Product Details
__
The DSP56011 is a high-performance programmable Digital Signal Processor (DSP) developed for Digital Versatile Disc (DVD), High-Definition Television (HDTV), and Advanced Set-top audio decoding. The DSP56011 is optimized with audio- specific peripherals and customized memory configuration, and may be programmed with Motorola’s certified software for Dolby AC-3 5.1 Channel Surround, Dolby Pro Logic, and MPEG1 Layer 2.
FEATURES
Digital Signal Processing Core
• 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 memoriesMemory
• Modified Harvard architecture allows simultaneous access to program and data memories
• 12800 × 24-bit on-chip Program ROM1
• 4096 × 24-bit on-chip X-data RAM and 3584 × 24-bit on-chip X-data ROM1
• 4352 × 24-bit on-chip Y-data RAM and 2048 × 24-bit on-chip Y-data ROM1
• 512 × 24-bit on-chip Program RAM and 64 × 24-bit bootstrap ROM
• As much as 2304 × 24 bits of X- and Y-data RAM can be switched to Program RAM, giving a total of 2816 × 24 bits of Program RAMPeripheral and Support Circuits
• SAI includes:
– Two receivers and three transmitters
– Master or slave capability
– I2S, Sony, and Matshushita audio protocol implementations
– Two sets of SAI interrupt vectors
• SHI features:
– Single master capability
– SPI and I2C protocols
– 10-word receive FIFO
– Support for 8-, 16- and 24-bit words.
• Byte-wide Parallel Host Interface with DMA support capable of reconfiguration as fifteen General Purpose Input/Output (GPIO) lines
• DAX features one serial transmitter capable of supporting S/PDIF, IEC958, CP-340, and AES/EBU formats.
• Eight dedicated, independent, programmable GPIO lines
• On-chip peripheral registers memory mapped in data memory space
• OnCE port for unobtrusive, processor speed-independent debugging
• Software programmable PLL-based frequency synthesizer for the core clock
• Power saving Wait and Stop modes
• Fully static, HCMOS design from specified operating frequency down to dc
• 100-pin plastic Thin Quad Flat Pack (TQFP) surface-mount package
• 5 V power supply -
