SDR-SDRAM Controller IP Core
Overview:
The Single
Data Rate (SDR) SDRAM Controller Core is designed for use in
applications requiring high memory throughput, high clock rates and full
programmability.
The core accepts commands using a simple local interface and translates
them to the command sequences required by SDR
SDRAM devices. The core also performs all initialization and refresh
functions.
The core uses bank management techniques to monitor the status of each
SDRAM bank. Banks are only opened or closed
when necessary, minimizing access delays. Up to eight banks can be
managed at one time. Access cascading is also supported, allowing read
or write requests to be chained together. This results in no delay
between requests, enabling up to 100% memory throughput.
The core is provided with run-time programmable inputs for all timing
parameters (tCL, tRC, tRCD, tRP, tMRD, tRRD, tRFC, tRAS, tWR) as well as
memory configuration settings. This ensures compatibility with all SDR
SDRAM configurations.
Three
optional add-on modules are available:
· Error Correction Coding (ECC) Module - Provides single bit correction
and double bit detection
· Read-Modify-Write Module (RMW) - Enables partial word writes when using ECC
· Multi-Burst Module - Enables long burst length requests and handles
address alignment for requests not aligned to the
boundaries of the programmed burst length
