20.3.2 eTPU Enhancements over TPU3
Freescale Semiconductor
• Test and development support features:
• The eTPU has several enhancements over the TPU3, most of which are detailed in the
• Increased data memory (SDM) address range (1.5 Kbytes) and width (32 bits per
• More interrupt types. Each eTPU channel can generate a data transfer request, in addition
— Hardware scheduler works as a ‘task management’ unit, dispatching event service
— Automatic channel context switch when a ‘task switch’ occurs; that is, one function
— Individual channel priority setting in three levels: high, middle, and low.
— Scheduler priority scheme allows calculation of worst case latency for event servicing
— SDM shared between host CPU and the eTPU engine, supporting channel-channel or
— Hardware implementation of four semaphores allows for resource arbitration between
— Hardware semaphores are directly supported by the microengine instruction set.
— Dual-parameter coherency hardware support allows coherent (to host) access to 2
— Coherent dual-parameter controller allows coherent (to microengine) accesses to two
— Debug support through the MCF5235 Debug port.
— Software breakpoints
— SCM (code memory) continuous signature-check built-in code integrity test multiple

DMA requests. This feature takes advantage of DMA peripherals which off-loads the host.
Interrupt overflow status is also provided.
