EPC-6 RadiSys VMEbus Controller

The RadiSys EPC-6 is a high-speed VMEbus module based on the Intel 80386SX processor. The 386SX has a 32-bit programming architecture but a 16-bit external data bus archi-tecture, combining the power of the 386 software environment with a compact and low-power hardware product. The EPC-6 can perform VMEbus master accesses, can be a VMEbus slave (by having its dual-port DRAM mapped onto the VMEbus), can be configured as the VMEbus slot-1 system controller, and can be an interrupter and interrupt handler. The EPC-6 is also a computer compatible with the IBM PC hardware architecture. The standard version of the EPC-6 contains, in ROM, a PC compatible BIOS and a ROM-based version of Microsoft MS-DOS. The EPC-6 also includes on-board nonvolatile flash memory supported as a DOS-compatible solid-state disk and file system. The user can store one or more embedded applications on the processor board and have them automatically invoked at system start-up. Another feature of the EPC-6 is a slot for an EXM expansion module. This allows some of the I/O of the EPC-6 to be customized for a particular application. The EPC-6 also has a slot for a coprocessor. You can add a 20MHz 80387SX floating-point coprocessor.


The RadiSys EPC-6A, a high-speed VMEbus module based on the Intel 80486DX2 processor, is a redesign of the EPC6 VMEbus module which is based on Intel 80386SX processor.
The EPC-6A computer is also compatible with the IBM PC hardware architecture. You can use the EPC-6A to perform VMEbus master accesses, act as a VMEbus slave, configure as the VMEbus SLOT-1 system controller, or act as an interrupter and interrupt handler.

The standard version of the EPC-6A contains, in ROM, a PC-compatible BIOS and a ROM-based version of Datalight ROM-DOS. The EPC-6A also includes on-board nonvolatile flash memory supported as a DOS-compatible solid-state disk and file system.
