**VL82C3216 Bus Expanding Controller Cache with write buffer ?
***Info:
The VL82C3216 Bus Expanding Controller (BANC) Cache with Write Buffer
is specifically designed to provide a high-performance, low-cost
solution for interfacing 386SX PC/AT-compatible chip sets to 386DX,
Am386DXL, AM386DXLV, 486DX, 486SX, or compatible processors. The
designs may be entirely new systems or upgrades to existing
ones. Power management features also make this device ideal for laptop
computers or other battery operated systems. The performance is
achieved through the use of a write buffer structure, an external
second level cache, prediction algorithms, and maximizing the internal
first level cache of the i486, if used.
The high level of integration is entered on the VL82C3216. It
controls all functions between the host processor bus and the 386SX
local bus. in addition the the write buffer and second- and
first-level cache controls, the VL82C3216 contains prediction and
burst mode algorithms that take full advantage of the page mode design
of existing 386SX system architecture. Through the use of pipelined
page mode accesses to system memory, the VL82C3216 bursts data to and
from memory at rates of up to 25 MB per second. This provides 32-bit
memory performance at 16-bit memory costs.
