Features
Multimode, multichannel decoder software functionality
— Dolby Digital and Pro Logic
— MPEG2 5.1
— DTS
— Bass management
Digital audio post-processing capabilities
— 3D Virtual surround sound
— Lucasfilm THX5.1
— Soundfield processing
— Equalization
Digital Signal Processing Core
— 100 MIPS with a 100 MHz clock at 3.3 V +/- 5
— Object code compatible with the DSP56000 core
— Highly parallel instruction set
— Data arithmetic logic unit (ALU)
– Fully pipelined 24 x 24-bit parallel multiplier-accumulator (MAC)
– 56-bit parallel barrel shifter (fast shift and normalization; bit stream generation and parsing)
– Conditional ALU instructions
– 24-bit or 16-bit arithmetic support under software control
— Program control unit (PCU)
– Position independent code (PIC) support
– Addressing modes optimized for DSP applications (including immediate offsets)
– On-chip instruction cache controller
– On-chip memory-expandable hardware stack
– Nested hardware DO loops
– Fast auto-return interrupts
— Direct memory access (DMA)
– Six DMA channels supporting internal and external accesses
– One-, two-, and three- dimensional transfers (including circular buffering)
– End-of-block-transfer interrupts
– Triggering from interrupt lines and all peripherals
— Phase-locked loop (PLL)
– Software programmable PLL-based frequency synthesizer for the core clock
– Allows change of low-power divide factor (DF) without loss of lock
– Output clock with skew elimination
— Hardware debugging support
– On-Chip Emulation (OnCE‘) module
– Joint Action Test Group (JTAG) test access port (TAP)
– Address trace mode reflects internal program RAM accesses at the external port
On-Chip Memories
— Modified Harvard architecture allows simultaneous access to program and data memories
— 30720 x 24-bit on-chip program ROM1 (disabled in 16-bit compatibility mode)
— 6144 x 24-bit on-chip X-data ROM1
— 6144 x 24-bit on-chip Y-data ROM1
— Program RAM, instruction cache, X data RAM, and Y data RAM sizes are programmable
— 192 x 24-bit bootstrap ROM (disabled in sixteen-bit compatibility mode)
Off-Chip Memory Expansion
— Data memory expansion to 256K x 24-bit word memory for P, X, and Y memory using SRAM.
— Data memory expansion to 16M x 24-bit word memory for P, X, and Y memory using DRAM.
— External memory expansion port( twenty-four data pins for high speed external memory access
allowing for a large number of external accesses per sample)
— Chip select logic for glueless interface to SRAMs
— On-chip DRAM controller for glueless interface to DRAMs
Peripheral and Support Circuits
— Enhanced serial audio interface (ESAI) includes:
– Six serial data lines, 4 selectable as receive or transmit and 2 transmit only.
– Master or slave capability
– I2S, Sony, AC97, and other audio protocol implementations
— Serial host interface (SHI) features:
– SPI protocol with multi-master capability
– I2C protocol with single-master capability
– Ten-word receive FIFO
– Support for 8-, 16-, and 24-bit words.
— Byte-wide parallel host interface (HDI08) with DMA support
— DAX features one serial transmitter capable of supporting S/PDIF, IEC958, IEC1937, CP-340,
and AES/EBU digital audio formats; alternate configuration supports up to two GPIO lines
— Triple timer module with single external interface or GPIO line
— On-chip peripheral registers are memory mapped in data memory space
• Reduced Power Dissipation
— Very low-power (3.3 V) CMOS design
— Wait and stop low-power standby modes
— Fully-static logic, operation frequency down to 0 Hz (dc)
— Optimized power management circuitry (instruction-dependent, peripheral-dependent, and
mode-dependent)
