1. Overview

Display out comparison unit

 Two channels

 Calculates the CRC code of an arbitrary graphics plane and compares it with the pre-calculated CRC

code.

 Specifies a rectangular area in an arbitrary graphics plane selected from among four graphics

planes, one plane of the graphics data obtained after α blending, or one plane of the data read from

the output video image generator of the video display controller 5.

 Pixel format

32 bits/pixel: ARGB8888/RGB888/RGB666

16 bits/pixel: RGB565

Renesas graphics processor

for OpenVGTM

 OpenVGTM, which is an open 2D vector graphics API, can be processed.

 Processes can be accelerated in OpenVGTM stage 2 to stage 8 using the dedicated hardware and

programmable shader.

JPEG codec unit

 Compression and decompression method conforming to the JPEG baseline standard within the

range described in this document.

 Operational precision: Conforming to JPEG Part 2, ISO-IEC10918-2

 Pixel format:

Compression: YCbCr422

Decompression: YCbCr444, YCbCr422, YCbCr411, YCbCr420

Output pixel format to the buffer: YCbCr422, ARGB8888, RGB565

 Four quantization tables provided

 Four Huffman tables provided (two tables for AC coefficients and two tables for DC coefficients)

 Markers supported: SOI, SOF0, SOS, DQT, DHT, DRI, RSTm, and EOI

 Image data rate: Max. 133.33 Mbytes/s (at 66.67-MHz operation)

Capture engine unit

 Examples of input video image size :

5 megapixels (2,560 × 1,920)

3 megapixels (2,048 × 1,536)

2 megapixels (1,632 × 1,224)

UXGA (1,600 × 1,200)

SXGA (1) (1,280 × 1,024)

SXGA (2) (1,280 × 960)

WXGA (1,280 × 768)

XGA (1,024 × 768)

SVGA (800 × 600)

WVGA (800 × 480)

VGA (640 × 480)

WQVGA (480 × 240)

QVGA (320 × 240, 240 × 320)

Note: Depends on the AC characteristics of the connected device, frame rate of the connected

device, and transfer speed to the destination RAM.

 Input format: 8- or 16-bit YCbCr422 binary data

 Memory output format: YCbCr422, YCbCr420

Note: The captured data cannot be displayed via the video display controller 5 because the Y data

and CbCr data are split when written to memory.

Pixel format converter

 Two channels

 Brightness adjustment, gain adjustment, and YCbCr and RGB mutual conversion.

 Input pixel data: RGB888, RGB565, YCbCr422

 Output pixel data: ARGB8888, RGB565, YCbCr422

Sound generator

 Four channels

 Capable of adjusting sound volume using 8-bit PWM output

 Four types of operating clocks (P0φ/2, P0φ/4, P0φ/8, and P0φ/16) can be selected.

 Frequency settings in the 25-Hz to 20-kHz range with precision of 1% or less

 Automatic attenuator function can be selected.

SD host interface

 Two channels

 SD memory I/O card interface (1-/4-bit SD bus)

 Error check function: CRC7 (command), CRC16 (data)

 Interrupt requests

—Card access interrupt

—SDIO access interrupt

—Card detect interrupt

 DMA transfer requests

—SD_BUF write

—SD_BUF read

 Card detection function, write protect supported
