Digital Audio Processor ■ Outline
The YSS950 (DAP1) is a DSP (Digital Signal Processor) for sound field processing, which features a high-speed/ high-precision 32-bit floating point DSP.
■ Features
{ 32-bit floating point DSP achieves high-speed/high-precision operations Operation frequency: Approximately 166 MHz Data bus width: 32 bits (24-bit mantissa, 8-bit exponent) Multiplier/adder: 32 bits × 32 bits + 55 bits → 55 bits (47-bit mantissa, 8-bit exponent) { 48 KB (12 Kword) preset command code firmware area { 24 KB (6 Kword) download command code firmware area (maximum) { 104 KB (26 Kword) data RAM area (maximum) { High-speed command code/coefficient data firmware download (burst transfer) { Download coefficients data firmware without any interruption of sound (runtime transfer) { Firmware’s placement order can be changed { Firmware’s number of execution channels can be changed (up to 16 channels) { Multiple firmware calls are enabled { Audio I/O 32 bits × 16 channels, TDM Fixed point decimal format and floating point decimal format (IEEE Standard 754, two’s complement) Sampling frequency range is 32 to 192 kHz Audio clock division/switch Input/output muting Input/output channel switching { External memory not required { General I/O ports (4) { On-chip PLL { Power supply voltage: 1.2 V (core), 3.3 V (pin) { Low power consumption: Approximately 130mW (typical value) { Si-gate CMOS process { Lead-free 64-pin SQFP package (YSS950-SZ)
