WinBook slc Mode D'Emploi
The Central Processing Unit
The Central Processing Unit (CPU) is the heart of any computer system, coordinating
the flow of data and controlling the hardware in a system.
The WinBook used the CYRIX CX486SLC CPU, which includes a built-in 1 Kbyte cache to
increase the speed of data access. The CPU uses a 32-bit internal data bus (path) and 16-bit
external data bus. Thus it offers the speed of 32-bit processing while still remaining fully
compatible with the 16-bit AT standard. Versions are available with a choice of CPU speed of
25MHz and 33MHz.

The WinBook uses the latest version of the CX486SLC CPU the “E” version. The “E” Version
supports the System Management Interrupt (SMI) feature, which in turn gives the WinBook state
of the art power management features (see chapter 8, for details).
