According to one embodiment, an electronic apparatus includes a housing, a circuit board in the housing, a cooling unit includes a radiator unit on the circuit board, and a cooling fan connected to the radiator unit and supported outside the circuit board in a floating state, a keyboard on a top wall of the housing, opposed to the circuit board and the cooling fan, a first supporting member disposed between the cooling fan and the keyboard and configured to support the keyboard when a key is depressed, and a second supporting member disposed between the cooling fan and a bottom wall of the housing and configured to support the cooling fan when a key is depressed. At least one of the first and second supporting members is formed of an elastic material.

Electronic apparatus

A FIFO control circuit for passing receive data and transmit data in a first-in first-out system, respectively, is provided. The FIFO control circuit comprises a receiving circuit; a transmitting circuit; a FIFO buffer for temporarily storing receive data received by the receiving circuit and transmit data to be transmitted by the transmitting circuit; a free space management circuit for managing free space of the FIFO buffer; a first address storage unit for storing an address range in which the receive data is stored in the FIFO buffer; a second address storage unit for storing an address range in which the transmit data is stored in the FIFO buffer; a write pointer control circuit writing the receive data and the transmit data; and a read pointer control circuit reading out the receive data and the transmit data from the FIFO buffer.
