When ERL = 1, useg and kuseg become unmapped
(virtual address is identical to the physical address) and
uncached. This behavior is the same as if there was a
TLB. This mapping is shown in Figure 2-5.
FIGURE 2-5:
2.3.2
The SRAM interface includes dual instruction and data
interfaces.
The dual interface enables independent connection to
instruction and data devices. It yields the highest
performance,
simultaneous I and D requests which are then serviced
in parallel.
The internal buses are connected to the Bus Matrix
unit, which is a switch fabric that provides this parallel
operation.

When the core is operating in MIPS16e mode,
instruction fetches only require 16 bits of data to be
returned. For improved efficiency, however, the core
will fetch 32 bits of instruction data whenever the
address is word-aligned. Thus for sequential MIPS16e
code, fetches only occur for every other instruction,
resulting in better performance and reduced system
power.
