Task: Question Answering
Input (English): passage: The Wii U uses a custom multi-chip module (MCM) developed by AMD, IBM and Renesas in co-operation with Nintendo IRD and Nintendo Technology Development. The MCM combines an ``Espresso'' central processing unit (CPU) and a ``Latte'' graphics chip (GPU), as well as a SEEPROM memory chip. The Espresso CPU, designed by IBM, consists of a PowerPC 750-based tri-core processor with 3 MB of shared L2 cache memory and clocked at approximately 1.24 GHz. Despite belonging to the PowerPC family, the Espresso also shares some architectural concepts with the POWER7 architecture, such as the use of eDRAM cache and being manufactured at a 45 nm node. The Latte graphics chip contains both a ``GX2'' GPGPU, which runs Wii U applications, and a ``GX'' GPU, which enables backward compatibility with Wii games. The GX2, designed by AMD, is based on the Radeon R600/R700 architecture and is clocked at approximately 550 MHz. It is manufactured at a 40 nm node and contains 32 MB of eDRAM cache memory, which can also act as L3 cache for the CPU. The GX, originally designed by ArtX, contains a 1 MB and a 2 MB banks of eSRAM cache memory. The Latte chip also includes a secondary custom ARM9 processor with 96 KB of SRAM memory that handles system tasks in the background during gameplay or while the system is in sleep mode, and dedicated hardware audio DSP module.
 question: does the wii u have a sleep mode?
Output (English): Yes
