L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101)
3
The L64118 processes the transport data packets in the PID Processing
Unit (PPU) according to the MPEG-2 standard draft 13818-1, making
Packetized Elementary Stream (PES), Program Specic Information
(PSI), Service Information (SI), and Private data available to the system.
It also buffers and transfers audio and video PES data packets to the
external decoder device.
The L64118 interfaces directly to LSI Logic’s L64105 MPEG-2 A/V
decoder. It outputs demultiplexed audio and video PES streams for
processing by the L64105. This decoder’s extended channel buffer
feature lets you use part of the L64118 SDRAM space to store A/V PES
data directed to the L64105. One benet of this is that it lets you free
memory in the L64105 and increases its On-Screen Display (OSD)
capability.
The L64118 also interfaces directly to LSI Logic’s family of single-chip
channel decoders (L64704, L64724, and L64768), which allows channel
data to be transferred in parallel or serial modes. The L64118
implements an automatic sync locking mechanism with a programmable
hysteresis function for reliable locking onto MPEG-2 (0x47) transport
packet sync bytes.
The External System Bus (EBus) is a general-purpose, 32-bit wide
system bus. It is controlled by the L64118 for communication with
external components in the system. This bus provides the system
designer with an interface that permits the glueless connection of devices
such as FLASH, ROMs, and external peripherals.
The L64118’s peripheral interface blocks let you connect external
systems directly to the set-top box. The RS232 ports let you connect a
PC, modem, or terminal directly to the chip. The IEEE1284 parallel port
lets you connect to fast peripheral devices and transfer ltered transport
packets. The IEEE1284 parallel port includes an on-chip DMA controller
for expediting data transfers between memory to, and from, the port.
The L64118 includes an infrared transmitter (blaster) port for applications
such as (remotely) programming a VCR, as well as two independent
infrared receiver ports, which can be used to program the set-top box
using a remote controller.
