IBM e-LAP reference design -- dubbed the "embedded Linux application platform" (e-LAP), this ready-to-use (and easily modified) PDA reference design based on IBM's PowerPC 405LP processor includes 32MB SDRAM, 32MB NOR Flash (NOR), 64MB DiskOnChip Flash, a 4-inch 240x320 pixel color LCD, a TCPA security chip, USB host/device, SDIO, and sound, plus a full Linux embedded software stack including a browser and a J2ME VM.
