MCF5307 Features
1.2 MCF5307 Features
The following list summarizes MCF5307 features:
1-4
• ColdFire processor core
• Multiply and accumulate unit (MAC)
• Hardware integer divide unit
• 8-Kbyte unified cache
• 4-Kbyte SRAM
— Variable-length RISC, clock-multiplied Version 3 microprocessor core
— Fully code compatible with Version 2 processors
— Two independent decoupled pipelines: four-stage instruction fetch pipeline (IFP)
— Eight-instruction FIFO buffer provides decoupling between the pipelines
— Branch prediction mechanisms for accelerating program execution
— 32-bit internal address bus supporting 4 Gbytes of linear address space
— 32-bit data bus
— 16 user-accessible, 32-bit-wide, general-purpose registers
— Supervisor/user modes for system protection
— Vector base register to relocate exception-vector table
— Optimized for high-level language constructs
— High-speed, complex arithmetic processing for DSP applications
— Tightly coupled to the OEP
— Three-stage execute pipeline with one clock issue rate for 16 x 16 operations
— 16 x 16 and 32 x 32 multiplies support, all with 32-bit accumulate
— Signed or unsigned integer support, plus signed fractional operands
— Unsigned and signed integer divide support
— Tightly coupled to the OEP
— 32/16 and 32/32 operation support producing quotient and/or remainder results
— Four-way set-associative organization
— Operates at higher processor core frequency
— Provides pipelined, single-cycle access to critical code and data
— Supports write-through and copyback modes
— Four-entry, 32-bit store buffer to improve performance of operand writes
— Programmable location anywhere within 4-Gbyte linear address space
— Higher core-frequency operation
— Pipelined, single-cycle access to critical code or data
and two-stage operand execution pipeline (OEP)
