The L64118’s embedded 32-bit MIPS CPU (TR4101) runs at 54 MHz.
The chip’s CPU block is 32 bit, while the bus interface to external
memory (through the SDRAM controller) is 16 bit. The CPU can run
MIPS16 and MIPS32 instructions. The 32-bit operations allow
high-performance operation, while 16-bit operations allow for code
optimization and memory savings. Since most transport processing and
filtering is implemented in hardware, much of the CPU’s processing
power can be devoted to system processing.
