Fast MitySOM-C10L project starts with SLL’s xSPI memory controller SLL-CL-MBMC
SLL’s Multiple Bus Memory Controller for Critical Link (SLL-CL-MBMC v3.2.x) supports the AP Memory x8 200 MHz PSRAM that is surface mounted on the following MitySOM product order codes:
- MITYSOM C10L-7Q-3X3-RI
- MITYSOM Development KIT, containing PCA, MitySOM-C10L Dev Board, P/N 80-001651
SLL-CL-MBMC is specifically designed to simplify customer uptake for fast project starts, even by designers who have never used xSPI memories before.
- The capabilities immediately available in SLL-CL-MBMC IP are expected to be suitable for most customer’s proprietary base boards using supported MitySOM.
Any MitySOM customers that need different capabilities than those available immediately in the SLL-CL-MBMC IP can contact info@synaptic-labs.com with your specific requirements. For example,
- If MitySOM customers require more than 150 MHz or x16 or dual channel; or
- If MitySOM customers want to surface mount any other additional xSPI memory device variant/s on their proprietary base-board connected to a supported CL MitySOM. You can select from the wide range of supported HyperBus, OctaBus, OctalBus or other Xccela Bus xSPI memory devices from up to 9 memory manufacturers including Everspin STT-MRAM.
Information about more capabilities can be found on SLL’s xSPI MBMC IP v.3.3.x product page.
- Visit our Customers webpage to see some examples of SLL memory controller customers around the globe and to see some examples of their many use cases and applications since 2016.
SLL-CL-MBMC v3.2.x Capabilities (other capabilities can be requested)
- Includes tight integration with Intel’s Platform Designer graphical system integration tool
- A simplified GUI user-interface to make adoption of the IP very easy in customer projects
- A maximum memory channel clock speed of 150 MHz DDR. This enables easy place-route and static timing sign off, even in complex customer designs.
- A maximum burst length of 32-bytes. This is usually enough to support efficient software performance.
- Features a high quality local interconnect, with support for the following interconnect protocols:
- Intel Avalon-MM protocol
- other interconnect protocols available on request…
- Includes internal clock-crossing circuitry between the local bus interconnect and the external memory channel. This reduces circuit area and improves the performance of the customer’s design
- Excellent memory access performance for both latency sensitive and bandwidth intensive applications:
- The round trip time for read memory transfer requests through the memory controller has been optimized for latency sensitive applications, such as processor cores.
- Note: SLL offers a range of cache technologies to significantly increase the performance of processor cores that do not have internal instruction and/or data caches when accessing external memories.
- Send your enquiry to info@synaptic-labs.com
- Features low circuit area and low SRAM usages, making SLL’s memory controller viable for use in resource constrained designs.
- Supports x8 data path width in a single instantiation of SLL’s memory controller IP
- Supports 1 instantiation of the memory controller IP accessing the surface mounted AP Memory PSRAM
- Please contact SLL at info@synaptic-labs.com if you require 2 or more instantiations of our memory controller IP in your Quartus project.
Remember: MitySOM customers that need any more capabilities in the SLL-CL-MBMC IP can contact info@synaptic-labs.com with your requirements.
Support for the Nios® V ecosystem on MitySOM-C10L
To quote the Intel website: ”Nios® V processor is the next generation of soft processor for Intel® FPGAs based on the open-source RISC-V Instruction Set Architecture.”
SLL-CL-MBMC reference designs are already available for the Nios® V ecosystem.
Note 1. Intel has not yet released Nios® V with cache. Intel is still updating the Nios® V support documentation.
Note 2. MitySOM-C10L customers that are early adopters of the Nios® V ecosystem may need to purchase some technical support hours from SLL to help implement their designs.
A calculator for estimating the effective bandwidth of the AP Memory PSRAM with SLL IP
For all DDRx SDRAM, and PSRAM devices, the effective memory bandwidth is always less than the wire speed. The effective memory bandwidth of your application using PSRAM devices depends on:
- The data path width of the memory channel (x8, x16, ..)
- The memory channel clock speed (ideally the highest speed supported by the memory device and SLL’s memory controller IP for that FPGA device family)
- The initial access latency (ideally the lowest value permitted by the PSRAM device for a given clock speed)
- The burst length of memory transfer requests issued to SLL’s memory controller IP (ideally 64 bytes or higher to PSRAM)
- The number of concurrently outstanding memory transfer requests issued to SLL’s memory controller IP (ideally 2)
- With all types of PSRAM devices, the temperature grade of the memory device impacts the maximum burst length of PSRAM devices.
- The choice of x8 Xccela PSRAM protocol does not have a significant impact on performance.
As a starting point, you can use SLL’s estimated effective bandwidth calculator below. It will help you to find the optimal burst length(s) for your application’s use-case when using SLL’s memory controller with a specific Xccela PSRAM device variant. {The calculator is only a guide and actual results in your hardware may be different. For more information contact SLL at info@synaptic-labs.com }
