**64200 (Wingine) High Performance 'Windows Engine' c:Oct91
***Info:
****General:...
****Wingine/CS4021 Interface:
CS4021 (also called the ISA486 chipset) is CHIPS' next generation high
end chipset. This chipset can support both 386 and 486 designs.
Special features are provided in the ISA486 chipset for a simple and
elegant interface to the Wingine subsystem. Figure 1 and Figure 2
show the Wingine/ISA486 interface [see datasheet].
Figure 1 shows the data path between the ISA486 memory controller and
Wingine memory. In VGA mode, Wingine interfaces to the ISA bus. In
this mode, display memory is controlled by Wingine. The CPU accesses
video memory through Wingine. In VGA mode, up to 512 Kbytes of video
memory is supported. In this mode, the VGA pin from Wingine is high
to isolate the data bus from ISA486. As Wingine has 17 address lines,
it is necessary to qualify memory read and memory writes with a val-
id VGA address. The external PAL decodes the upper address (LA17
-LA23) from the ISA bus for a valid VGA access (0A0000 - 0BFFFFh) and
qualifies the MEMR/ and MEMW/ signals to Wingine.
When the 64200 is switched to 'Windows Accelerator' (or Wingine) mode,
the ISA486 chipset can access video memory directly for much higher
video performance. In this mode up to 2 Mbytes of display memory can
be supported. Figure 1 shows a 1MB implementation. In 'Wingine' mode
the full 32 bit memory bus can be utilized for accessing display
memory. In this mode, Wingine tristates its memory bus and pulls the
VGA pin low. The two data buffers on the upper 16 bits of the memory
bus are ena- bled allowing the ISA486 memory controller to access
video memory directly. The direction of the data buffers is
controlled by an external signal derived from the RAS/, CAS/, and WE/
signals from ISA486. For Write operations, data is driven onto the
video memory data lines. During read cycles, the buffers are turned
around to drive the data onto the system memory bus.
The XREQ/ signal from Wingine is used to request a transfer cycle from
the system memory controller. The memory controller will perform a
transfer cycle to the video RAMs when XREQ/ goes active. Figure 2
shows the interface for address and control lines. During VGA modes,
the ISA486 memory controller is isolated from video memory by pulling
the VGA pin high. The addresses and control signals for video memory
are generated by Wingine. In 'Wingine' mode, the VGA pin goes low and
the system memory controller drives the address and control lines.
The Wingine memory bus is tristated during this mode.
