The model takes Tricore 64-bit assembly language blocks as input and provides a discrete probabilistic distribution for the execution time of the given block. The distribution can be used to sample mean execution time of the assembly code.
Highlights
Use the model to optimize your code based on the generated assembly, leveraging learned performance patterns
Predicts a probability distribution of execution time (in nanoseconds for Aurix Tricore TC399) for each block on the ARM Cortex-A53 core
Extracts key timing metrics: Mean, Standard Deviation (STD), Max, and Median to understand performance variability at the ASM level
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay by the hour for model inference on the ml.g5.xlarge instance type. Both options use the same instance size, so pricing scales with how many host hours you run. The two dimensions differ by processing mode. Batch mode handles inference in grouped jobs. Real-time mode serves inference as requests arrive. Pick the mode that fits your workload, then multiply the hourly rate by hours used. There are no seats, tiers, or upfront commitments. Billing follows your actual usage.
Top-of-mind questions for buyers
What do I get on an ml.g5.xlarge host hour, and what does this product do?
You pay per host hour for a GPU-backed ml.g5.xlarge instance running the LOCI model. The model predicts time distribution for the Aurix Tricore ASM target. It reads compiled binaries and predicts timing behavior without running or simulating your code.
Am I charged when the instance is stopped or idle?
Charges accrue per host hour while the instance runs. Fully stopped instances do not accrue software host-hour charges. Underlying AWS storage or related resources may still bill separately. The software meters running time only, so you pay for hours the instance is active.
How does batch mode billing differ from real-time mode mechanically?
Both bill the same ml.g5.xlarge instance by host hour. Batch mode processes inference in grouped jobs, so you run hours only during job windows. Real-time mode keeps the instance available to serve requests as they arrive, so hours accrue across the serving window.

An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Deploy the model on Amazon SageMaker AI using the following options:
Real-time inference
Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference .
Batch transform
Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI .

Inputs
Summary
The input has to be a csv file, with one column named 'r.asm'. Each row can be assembly code based on the TriCore 64-bit architecture.
The code snippet below shows how to load the data in Python using the pandas package.
data = pandas.read_csv('../data/tricore_dataset.csv')
More detailed example is available in the Jupyter notebooks.
Limitations for input type
The csv file should have less than 2000 rows, for optimal performance. It is recommended that the length of one sample of assembly code is not longer than 500 instructions.

The Loci-Stream CFD code is a scalable parallel tool for fluid-flow and heat transfer simulations in large scale industrial applications. Many of the common features found in other standard CFD tools such as ANSYS-Fluent and Star-CCM+ are available. If you are interested in testing Loci-Stream, see the tutorials page on our website which contains run control and grid files for a number of cases that can be run directly.
