M11

Q-BUS SBC

Technology From Mentec

Double your Q-BUS processor performance

The M11, Mentec's PDP emulation, provides the highest performance ever achieved on Q-BUS PDP-11 applications and gives the essential speed increase that customers demand without changing existing proven software. The M11 can in most applications increase performance by up to 100%, providing the best price/performance ratio available on Q-BUS. M11 Processor Picture
The single quad module operates as host processor on the Q-BUS. By using high performance microsequencers, ALU's and FPGA technologies to implement the PDP-11 instruction set, the M11 perfectly emulates the famous DEC J11 microprocessor. The SBC M11 also interfaces to the 22-bit Q-BUS and supports block module DMA. This provides for total compatability with all PDP operating systems and software while overcoming the performance restrictions of the J11 microprocessor.

Processor
The M11 is a high performance PDP-11 similar in functionality to previous Mentec PDP11 CPU's. PDP-11 instructions are implimented by a microprogrammed subsystem based on the TI 8832 ALU and the TI 8818A microsequencer. Console ODT and floating point instruction emulation are performed by the i960 processor block. Floating point emulation is available only with microcode revisions 2.0 or later. It should be noted that internally IEEE format floating point is used for emulation.
Memory
The module contains 1Mb/2Mb/3Mb/4Mb of Q-BUS SRAM. The module's SRAM is accessible by other system devices over the Q-BUS using DMA.
LSI-BUS Interface
The module interfaces to the extended LSI-11 bus and can address up to 4Mb of main memory and communicate with other bus devices, e.g. disk controllers (RQDX-3) or asynchronous serial line mux (DHV11). The 22-bit extended LSI-11 bus is completely downward compatible with the standard LSI-11 bus.
