Cyrix 486 CPUs

Cyrix Foundry Agreements

Cyrix extended its wafer supply agreement with SGS-Thomson in 1994 (Originally
formed in 1990). Under the new arrangement,
SGS-Thomson increased the number of wafers it produces for Cyrix and
is allowed to make a certain
percentage of those same wafers for itself. In addition, Cyrix granted
SGS-Thomson the right to use
certain Cyrix-designed chips as part of SGS-Thomson’s ASIC libraries.
SGS-Thomson is allowed to
produce and sell such ASIC products under its own name in unlimited
quantities, with Cyrix receiving
royalties from the sale of the devices. Also, Cyrix has the right to
sell the SGS Thomson-designed ASICs
under its own name.


IBM and Cyrix announced a five-year agreement in (Sept 1993) calling
for IBM to manufacture Cyrix’s 486, 5×86,
and 6×86 MPUs. The two companies equally share the output of the Cyrix-designed
chips. (Terminated in 1998 after The National Buy Out)

Differentiating between Cyrix and IBM Blue Lightning

It is difficult to distinguish IBM Blue Lightning CPU from Cyrix CPU.
The behavior of both CPU is very similar to each other. The deference
is that IBM Blue Lightning CPU supports MSR but Cyrix 486, 5×86 and
6×86 do not support it. This means that wrmsr instruction cause invalid
opcode fault on Cyrix 486, 5×86 and 6×86, but does not on IBM Blue Lightning
CPU. To detect invalid opcode by wrmsr, the following handler is prepared:

static volatile u_int trap_by_wrmsr;

inthand_t bluetrap;

movl $0xa8c1d, _trap_by_wrmsr
addl $2, (%esp)

If we have Cyrix 486, 5×86 or 6×86, the variable trap_by_wrmsr will
be change by this handler. Once Cyrix CPU is detected by this method,
we will check device ID register to distinguish it.

One of the 4 Court Cases Involving Cyrix

These cases (and the Intel vs ULSI case) were landmark
in the definition of patent exhaution law as applied to technology IP

Cyrix was sued 3 times by Intel, and one all 3 times

Cyrix sued Intel once (Intels Pentium Pro infringed on a Cyrix Patent)
Intel settled out of court for an undisclosed sum and granted Cyrix
full cross liscesing with Intel.
