Mâ¢CORE M210 Central Processor Unit (CPU)
6.3 Features
The streamlined execution engine uses many of the same performance
enhancements and implementation techniques incorporated in desktop
RISC processors. A strictly defined load/store architecture minimizes
control complexity. Use of a fixed, 16-bit instruction encoding
significantly lowers the memory bandwidth needed to sustain a high rate
of instruction execution, and careful selection of the instruction set
allows the code density and overall memory efficiency of the Mâ¢CORE
architecture to surpass those of complex instruction set computer
(CISC) architectures.
These factors reduce system energy consumption significantly, and the
fully static Mâ¢CORE design uses other techniques to reduce it even
more. The core uses dynamic clock management to automatically
power-down internal functions that are not in use on a clock-by-clock
basis. It also incorporates three power-conservation operating modes,
which are invoked via dedicated instructions.
The main features of the Mâ¢CORE are:
⢠32-bit load/store RISC architecture
⢠Fixed 16-bit instruction length
⢠16 entry, 32-bit general-purpose register file
⢠Efficient 4-stage execution pipeline, hidden from application
software
⢠Single-cycle execution for most instructions, 2-cycle branches and
memory accesses
⢠Support for byte/half-word/word memory access
⢠Fast interrupt support, with 16 entry user-controlled alternate
register file
⢠Vectored and autovectored interrupt support
⢠On-chip emulation support
⢠Full static design for minimal power consumption
