BU9543KV-E2 - Brand New Rohm Semiconductor Special Purpose Audio ICs
-
Description
The BU9543KV-E2 is a special purpose audio Integrated Circuit (IC) designed for digital signal processing. It is developed specifically for high-performance audio decoding applications such as Digital Versatile Disc (DVD), High-Definition Television (HDTV) and Advanced Set-top audio decoding. This IC is optimized with audio-specific peripherals and a customized memory configuration. It is programmable with Motorola’s certified software for Dolby AC-3 5.1 Channel Surround, Dolby Pro Logic, and MPEG1 Layer 2.
Specifications and features
The BU9543KV-E2 boasts the following features:
- Digital Signal Processing Core
- Efficient, object-code compatible, 24-bit DSP56000 family DSP engine
- 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 optimized 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
