Processor core:
MIPS M4K with 5-stage pipeline
MIPS32-compatible Release 2 Instruction Set
MIPS16e Code Compression to improve code density by up to 40%
GPR shadow registers to minimize latency for interrupt handlers
Bit field manipulation instructions
High-performance Multiply/Divide Unit:
- Maximum issue rate of one 32x16 multiply per clock
- Maximum issue rate of one 32x32 multiply every other clock
Static implementation: minimum operating frequency 0 MHz
2.3 to 3.6V operation with full speed over entire range
Low-power modes including RUN, IDLE, and SLEEP
Memory:
Unified 4GB virtual memory space
Fixed Memory Mapping Translation (FMT) mechanism
Flexible partitioning into kernel and user accessible memory segments for
increased application stability
Pre Fetch Cache:
16 lines, each 128-bit wide, instruction Prefetch buffer
Ability to load and lock lines – useful to create SW breakpoints in Flash and
minimize interrupt latency
Interrupt Controller:
Fully programmable interrupt controller with Single or Multi vector mode, support-
ing up to 95 IRQs.
Multiple priorities and subpriorities for each vector
Highest priority interrupt has dedicated register set for reduced interrupt latency
DMA Controller:
Up to 4 independent channels
Memory-to-Memory, Memory-to-Peripheral, and Peripheral-to-Memory transfers
Programmable trigger from any IRQ
Chainable channels, stop on match detection, Auto-Enable mode
Data transfers can occur while the core is in IDLE mode
Integrated programmable CRC engine: calculates on the fly while the data is
transferred.
Enhanced Parallel Master Port:
8- and 16-bit data interface
Up to 16-bit address lines, expandable using GPIO lines
2 Chip Select lines
