IDT79R3041 INTEGRATED RISController FOR LOW COST SYSTEMS

COMMERCIAL TEMPERATURE RANGE

System Control Co-Processor

dress decoding, or in other system specific forms. In systems

which do not wish to implement memory protection, and wish

to have the kernel and user tasks operate out of a single

unified memory space, upper address lines can be ignored by

the address decoder, and thus all references will be seen in

the lower gigabyte of the physical address space.

TheR3041addsadditionalresourcesintotheon-chipCP0.

These resources are detailed in the R3041 User's Manual.

They allow kernel software to directly control activity of the

processor internal resources and bus interface, and include:

• Cache Configuration Register: This register controls the

data cache block size and miss refill algorithm.

• Bus Control Register: This register controls the behavior

of the various bus interface signals.

• Count and Compare Registers: Together, these two

registers implement a programmable 24-bit timer, which

can be used for DRAM refresh or as a general purpose

timer.

The R3041 also integrates on-chip a System Control Co-

processor, CP0. CP0 manages the exception handling capa-

bility of the R3041, the virtual to physical address mapping of

the R3041, and the programmable bus interface capabilities

of the R3041. These topics are discussed in subsequent

sections.

TheR3041doesnotincludetheoptionalTLBfoundinother

membersoftheRISControllerfamily,butinsteadperformsthe

same virtual to physical address mapping of the base version

of the RISController family. These devices still support

distinct kernel and user mode operation, but do not require

page management software or an on-chip TLB, leading to a

simpler software model and a lower-cost processor.

The memory mapping used by these devices is illustrated

in Figure 3. Note that the reserved address spaces shown are

for compatibility with future family members; in the current

family members, references to these addresses are trans-

lated in the same fashion as their respective segments, with

no traps or exceptions taken.

• PortSizeControlRegister: Thisregisterallowsthekernel

to indicate the port width of reads and writes to various sub-

regionsofthephysicaladdressspace. Thus,theR3041can

interface directly with 8-, 16-, and 32-bit memory ports,

including a mix of sizes, for both instruction and data

references, without requiring additional external logic.

When using the base versions of the architecture, the

system designer can implement a distinction between the

user tasks and the kernel tasks, without having to execute

page management software. This distinction can take the

form of physical memory protection, accomplished by ad-
