Microprocessor Options

The MVME162 provides scalability by allowing many types of MPU options. Features such as clock speed and floating point capability can be specified by the user.

VMEbus-Interface

The VMEbus-Interface ASIC includes a local bus to and from the VMEbus-DMA controller,

VME board support functions, and global control and status registers (GCSRs) for microprocessor communication.

The device also supports the VME D64 specification, further improving system performance.
