Preliminary Datasheet

Functional Overview
As indicated in
Figure 1
, the 80960VH combines many features with the 80960JT to create a
highly integrated processor. Subsections following the figure briefly describe the main features; for
detailed functional descriptions, refer to the
i960
VH Processor Developer’s Manual.
The PCI bus is an industry standard, high performance, low latency system bus that operates up to
132 Mbyte/sec. The 80960VH is fully compliant with the
PCI Local Bus Specification
, revision
2.2. Function 0 is the address translation unit.
The 80960VH, object code compatible with the i960 core processor, is capable of sustained
execution at the rate of one instruction per clock.
The local bus, a 32-bit multiplexed burst bus, is a high-speed interface to system memory and I/O.
A full complement of control signals simplifies the connection of the 80960VH to external
components. Physical and logical memory attributes are programmed via memory-mapped control
registers (MMRs), an extension not found on the i960 Kx, Sx or Cx processors. Physical and
logical configuration registers enable the processor to operate with all combinations of bus width
and data object alignment.
