The SH7785 incorporates a DDR2-SDRAM interface, a PCI controller, a DMA controller, timers,
serial interfaces, audio interfaces, a graphics data translation accelerator (GDTA) that supports
YUV data conversion and motion compensation processing, and a display unit (DU) that supports
digital RGB display. The DDR2 interface, PCI interface, and the local bus are independent,
providing dedicated external bus interfaces for the transfer of large amounts of data and of
streaming data.
The SH7785 contains an SH-4A (PVR.VER = H'30: Extended version), which is a 32-bit RISC
(reduced instruction set computer) multiprocessor including an FPU as well as a CPU, providing
upward compatibility (instruction set level) with the SH-1, SH-2, SH-3, and SH-4
microcomputers. The CPU and FPU run at 600 MHz. The processor also includes an instruction
cache, an operand cache for which copy-back or write-through mode is selectable, a four-entry
fully associative instruction TLB (translation look-aside buffer), and an MMU (memory
management unit) with a 64-entry fully associative unified TLB.
