Introduction

1.5.2

Crossbar switch (XBAR)

The XBAR multi-port crossbar switch supports simultaneous connections between four master ports and three slave ports. The

crossbar supports a 32-bit address bus width and a 64-bit data bus width.

The crossbar allows four concurrent transactions to occur from any master port to any slave port, although one of those transfers

must be an instruction fetch from internal flash memory. If a slave port is simultaneously requested by more than one master

port, arbitration logic selects the higher priority master and grants it ownership of the slave port. All other masters requesting

that slave port are stalled until the higher priority master completes its transactions.

The crossbar provides the following features:

•

4 masters and 3 slaves supported per each replicated crossbar

— Masters allocation for each crossbar: e200z4d core with two independent bus interface units (BIU) for I and D

access (2 masters), one eDMA, one FlexRay

— Slaves allocation for each crossbar: a redundant flash-memory controller with 2 slave ports to guarantee maximum

flexibility to handle Instruction and Data array, one redundant SRAM controller with 1 slave port each and 1

redundant peripheral bus bridge

•

32-bit address bus and 64-bit data bus

Programmable arbitration priority

— Requesting masters can be treated with equal priority and are granted access to a slave port in round-robin method,

based upon the ID of the last master to be granted access or a priority order can be assigned by software at

application run time

•

Temporary dynamic priority elevation of masters

The XBAR is replicated for each processing channel.

1.5.3

Memory Protection Unit (MPU)

The Memory Protection Unit splits the physical memory into 16 different regions. Each master (eDMA, FlexRay, CPU) can be

assigned different access rights to each region.

•

16-region MPU with concurrent checks against each master access

32-byte granularity for protected address region

The memory protection unit is replicated for each processing channel.

1.5.4

Enhanced Direct Memory Access (eDMA)

The enhanced direct memory access (eDMA) controller is a second-generation module capable of performing complex data

movements via 16 programmable channels, with minimal intervention from the host processor. The hardware microarchitecture

includes a DMA engine which performs source and destination address calculations, and the actual data movement operations,

along with an SRAM-based memory containing the transfer control descriptors (TCD) for the channels. This implementation

is used to minimize the overall block size.

The eDMA module provides the following features:

•

16 channels supporting 8-, 16-, and 32-bit value single or block transfers

Support variable sized queues and circular buffered queue

Source and destination address registers independently configured to post-increment or stay constant

Support major and minor loop offset

Support minor and major loop done signals

DMA task initiated either by hardware requestor or by software

Each DMA task can optionally generate an interrupt at completion and retirement of the task

Signal to indicate closure of last minor loop
