MOTOROLA MVME162PA-242E processor module

Utilizes the fourth-generation processor of Motorola's 68000 series (MC68040), supporting 32-bit data and address buses, with the ability to address 4GB of memory space.

Integrates an 8KB instruction/data cache and adopts a Harvard architecture (separate instruction and data caches) to reduce memory access conflicts and enhance instruction execution efficiency.

Supports virtual memory and memory protection mechanisms, enabling memory isolation for multitasking operating systems (such as task space protection in VxWorks) to prevent program crashes from affecting the entire system.

Provides 4 TLB (Translation Lookaside Buffer) entries to accelerate the conversion from virtual to physical addresses and improve memory access speed.

Optionally integrates the MC68882 FPU, supporting the IEEE 754 double-precision floating-point standard with a floating-point performance of 1.8 MFLOPS (million floating-point operations per second). This is suitable for scientific computing, signal processing, and other scenarios (e.g., image reconstruction algorithms in medical devices).

With a 25MHz clock speed and 12.5 MIPS processing capability, it can complete PID control algorithm calculations within 1ms, suitable for high-precision motion control (e.g., multi-axis linkage in CNC machine tools).

With FPU support, it can handle moderately complex digital filter algorithms (e.g., FIR/IIR filtering) for real-time noise cancellation of industrial sensor signals.

MMU support allows simultaneous execution of control tasks (e.g., device monitoring) and communication tasks (e.g., network data transmission), with task switching latency <10μs (in VxWorks environment).
