Crossbar switch (XBAR)
The XBAR multi-port crossbar switch supports simultaneous connections between three master ports and three slave ports. The
crossbar supports a 32-bit address bus width and a 32-bit data bus width.
The crossbar allows for two concurrent transactions to occur from any master port to any slave port; but 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 will select the higher priority master and grant it ownership of the slave port. All other masters requesting
that slave port will be stalled until the higher priority master completes its transactions. Requesting masters will be treated with
equal priority and will be granted access a slave port in round-robin fashion, based upon the ID of the last master to be granted
access.
The crossbar provides the following features:
3 master ports:
— e200z0 core complex instruction port
— e200z0 core complex Load/Store Data port
—eDMA
3 slave ports:
— Flash memory (Code and Data)
—SRAM
— Peripheral bridge
32-bit internal address, 32-bit internal data paths
Fixed Priority Arbitration based on Port Master
Temporary dynamic priority elevation of masters
1.5.3
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 micro architecture
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.
The eDMA module provides the following features:
16 channels support independent 8-, 16- or 32-bit single value or block transfers
Supports variable-sized queues and circular queues
Source and destination address registers are independently configured to either post-increment or to remain constant
Each transfer is initiated by a peripheral, CPU, or eDMA channel request
Each eDMA channel can optionally send an interrupt request to the CPU on completion of a single value or block
transfer
DMA transfers possible between system memories, DSPIs, ADC, FlexPWM, eTimer and CTU
Programmable DMA channel multiplexer allows assignment of any DMA source to any available DMA channel with
as many as 30 request sources
eDMA abort operation through software
1.5.4
Flash memory
The MPC5602P provides 320 KB of programmable, non-volatile, flash memory. The non-volatile memory (NVM) can be used
for instruction and/or data storage. The flash memory module is interfaced to the system bus by a dedicated flash memory
controller. It supports a 32-bit data bus width at the system bus port, and a 128-bit read data interface to flash memory. The
module contains four 128-bit wide prefetch buffers. Prefetch buffer hits allow no-wait responses. Normal flash memory array
accesses are registered and are forwarded to the system bus on the following cycle, incurring two wait-states.
