Philips Semiconductors
MPEG2 Transport RISC processor
Preliminary specification
SAA7219
1 FEATURES
• Conditional access descrambling Digital Video
Broadcasting (DVB) compliant and MULTI2 compliant
• Stream demultiplexing: Transport Stream (TS),
Packetized Elementary Stream (PES), program and
proprietary streams
• Internal 32-bit MIPS RISC based Central Processing
Unit (CPU) supporting MIPS16 instruction set and
running at 81 MHz
• Low-power sleep modes supported across the chip
• Comprehensive driver software and development tool
support
• Package: SQFP208.
1.1 External interfaces
• Versatile compressed stream input at 108 Mbits/s
• A 32-bit microcontroller extension bus supporting
DRAM, SDRAM, Flash, (E)PROM and external memory
mapped I/O devices. It also supports a synchronous
interface to communicate with the integrated MPEG
Audio Video Graphics Decoder (AVGD) SAA7215 at
40.5 Mbytes.
• An IEEE 1284 interface (Centronics) supporting master
and slave modes. Usable as a general purpose port.
• An interface to IEEE 1394 devices (such as Philips
PDI 1394 chip-set)
• Two UART (RS232) data ports with Direct Memory
Access (DMA) capabilities (187.5 kbits/s) including
hardware flow control signals RXD, TXD, RTS and CTS
for modem support
• A Synchronous Serial Interface (SSI) to connect an
off-chip modem analog front-end
• An elementary UART with DMA capabilities, dedicated
to front panel devices for instance
• Two dedicated smart-card reader interfaces (ISO 7816
compatible) with DMA capabilities
• Two I2C-bus master/slave transceivers with DMA
capabilities, supporting the standard (100 kbit/s) and
fast (400 kbits/s) I2C-bus modes
• 32 general purpose, bidirectional I/O interface pins, 8 of
which may also be used as interrupt inputs
• One Pulse Width Modulated (PWM) output with 8-bit
resolution
• A General Purpose/High Speed (GP/HS) interface
supporting stream recording through IEEE 1394
interface IC
• An extended JTAG interface for board test support.
1.2 CPU related features
The SAA7219 contains an embedded RISC CPU, which
incorporates the following features:
• A 32-bit PR3930 core running at 81 MHz
• 8-kbyte, 2-way set associative instruction cache
• 4-kbyte, 4-way set associative data cache
• A programmable Low-power mode, including wake-up
on interrupt
• A memory management unit with 32 odd/even entries
and variable page sizes
• Multiply/accumulate/divide unit with fast
multiply/accumulate for 16-bit and 32-bit operands
• Two fully independent 24-bit timers and one 24-bit timer
including watchdog facilities
• A real-time clock unit (active in Sleep mode)
• Built-in software debug support unit as part of Extended
Enhanced JTAG debug interface
• On-chip SRAM of 4 kbytes for storing code which needs
fast execution.
1.3 MPEG-2 systems features
• Hardware based parsing of Transport Stream (TS),
Philips Semiconductors program and proprietary
software data streams. Maximum input rate is
108 Mbits/s.
• A real-time descrambler consisting of 3 modules:
– A control word bank containing 14 pairs (odd, even)
of control words and a default control word
– The DVB descrambler core implementing the stream
decipher and block decipher algorithms
– The MULTI2 descrambler algorithm implementing
the CBC and OFB mode descrambling functions.
