Description
The DSPB56374AF is a programmable digital signal processor designed for audio decoding in high-performance applications such as DVD, HDTV, and advanced set-top boxes. This electronic component is optimized with audio-specific peripherals, customized memory configuration, and is capable of running Motorola’s certified software for Dolby AC-3, Dolby Pro Logic, and MPEG1 Layer 2.
Specifications and 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 memories
Memory:
- 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 RAM
Peripheral 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
