L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101)
7
General
On-chip PLL (54 MHz) with internal loop lter
JTAG support
256-pin Plastic Ball Grid Array (PBGA) Package
Commercial temperature range 0 °C–70 °C ambient
Low-power, 3.3 V (± 10%) process
Architectural Overview
The components of the L64118 are integrated to provide a complete
system solution for demultiplexing and processing incoming MPEG-2
Transport Stream packets. Figure 2 shows the three main blocks of the
L64118: the TR4101 CPU and associated core building blocks, the
transport (demultiplexer) block, and the peripheral device interfaces.
Additionally, the L64118 has three main buses:
Basic Bus (BBus)
The BBus is an internal 32-bit bus that connects the CPU core and
building blocks with internal memory and peripherals through the
CPU-to-Peripheral (C2P) bridge.
Peripheral Bus (PBus)
The PBus is the internal peripheral bus; it links the CPU to SDRAM
memory, internal peripheral devices, and the demultiplexer using the
C2P bridge.
External System Bus (EBus)
The EBus is a general-purpose 16- and 32-bit synchronous system
bus that lets the L64118 communicate with external components in
the system. The EBus connects to the BBus through the EBus
controller.
The following subsections provide an overview of the chip’s main blocks.
