developed based on the MIPS III architecture of MIPS Technologies, Inc. (MIPS). For details of the
TX49/H3 core such as instruction sets, see “64-bit TX System RISC TX49/H2, TX49/H3, TX49/H4 Core
Architecture”.
External Bus Controller, DMA Controllers, SDRAM Controller, PCI Controller. The TX4937 also has
peripheral circuits such as a serial I/O port, a timer/counter, a parallel I/O port, an AC-link Controller and an
Interrupt Controller. By having an on-chip a data bus with a maximum width of 64 bits and an SDRAM
Controller with a memory clock frequency of 133 MHz, the TX4937 realizes low memory access latency and
high memory bandwidth. This allows the TX4937 to show its capacity as a high-performance CPU core.
