Renesas Technology America, Inc., (San Jose, CA) has released the SH-MobileR2 application processor for portable multimedia systems. The device enables the design of portable and mobile devices with multimedia capabilities that are suitable for personal navigation devices, portable media players, and video and voice over IP (V2IP) terminals.
The SH-MobileR2 incorporates the SH-4A CPU core that operates at up to 400MHz and has a floating-point processing unit (FPU) that increases the efficiency of video and audio processing. At 400MHz, processing performance is 720 MIPS and FPU performance is 2.8 GFLOPS. The SH-MobileR2 handles parallel processing of multiple applications and general-purpose operating systems such as Windows® CE or Linux. The SH-MobileR2's 64byte primary cache memory is supplemented by a new 256Kbyte secondary cache memory that contributes to faster software execution.
The application processor features the Video Processing Unit 5F (VPU5F) multi- CODEC function, an IP block that achieves high performance with low power consumption. The VPU5F can perform VGA-size encoding and decoding at a rate of 30 frames per second. The SH-MobileR2's 2-D graphics accelerator provides enhanced functionality and performance for faster, better-quality map rendering. Other peripheral functions include USB 2.0 host/function support (high-speed), an ATAPI controller that allows connection to a hard disk or DVD drive, and an SD host controller with high-speed specification capability.
