The SH7722 is a system LSI that incorporates an SH4AL-DSP microcontroller with a clock speed

of up to 333 MHz as its core, together with a variety of functions required for multimedia

applications. These include MPEG4 and H.264 accelerators, a 2D graphics accelerator, LCD

controller, camera interface, and sound input/output module.

The SH4AL-DSP microcontroller is a 32-bit RISC-type SuperH architecture CPU with a DSP

extension function, and is a new generation CPU core which is upward compatible with SH-1,

SH2, and SH3-DSP at the instruction set level. Super scalar design in which two instructions are

executed simultaneously allows high-speed processing. In addition, the strong power-management

functions keep both operating current and standby current low.

This LSI is ideal for use in multimedia devices that require both high-performance operation and

low power consumption.
