===== SUBMISSIONS =====
TCRS ‘26 will work with IEEE Embedded Systems Letters (ESL, https://ieee-ceda.org/publication/esl) for paper submissions, reviews, and publication. Submissions meeting IEEE ESL requirements will be published in the special issue of TCRS in IEEE ESL. All submissions must be written in English. Only original papers that have not been submitted or published in other conferences or journals will be considered.

Papers submitted to TCRS ‘26 must follow the IEEE ESL Paper Submission Instructions (https://ieee-ceda.org/publication/esl/esl-paper-submission). Submitted manuscripts must be four pages or fewer, including all figures, tables, and references. Submissions exceeding this length will be returned without review. Papers should use 7.875 in x 10.75 in (20 cm x 27.30 cm) trim size and the IEEE transactions two-column format in 10-pt. font. The review process is blind (not double-blind); please do not submit anonymized manuscripts.

Submissions will be managed through the IEEE Author Portal for IEEE ESL (https://ieee.atyponrex.com/journal/les-ieee).

Once you are signed in to the IEEE Author Portal, click on “Start submission” at the top right. Then, click on “Article Type” under the “Your Progress” menu on the right. On the next page, choose “TCRS 2026” under the dropdown menu. After confirming the check boxes, you will be prompted to upload your manuscript.

In addition to the manuscript, the authors are required to submit a document for Conflict of Interest (COI) with the program committee members through the IEEE Author Portal. The authors are required to submit the COI document during the submission process.

Please see here for more details: https://www.tcrs.io/cfp/

===== Review Process =====
At least one of the authors for each paper must fully register and present the accepted paper at the workshop. TCRS '26 will have two tiers of final acceptance.

1. Present-only acceptance.
2. Present-and-publish acceptance.
The Present-only tier acceptance will be given to the submissions that meet the TCRS workshop quality requirements. The Present-and-publish tier acceptance will be given to the submissions that are accepted for presentation at the TCRS workshop and considered for publication in the IEEE ELS journal.

All papers with any of these two tiers of acceptance will be presented at the workshop and distributed as the proceedings of the workshop. However, only the papers with the Present-and-publish tier acceptance will be published in the IEEE ESL special issue of TCRS.

===== REVIEW PROCESS =====
Authors of the submissions will be notified with the first round of reviews. Below are the subsequent processes for accepted papers.

1. Present-only acceptance
Papers that are not accepted for publication in the IEEE ESL journal may still be eligible to present at the workshop. In this case, the authors will receive a "reject" from IEEE ESL and a separate "Present-only" acceptance notification from TCRS. Authors of a submission with Present-only acceptance will be asked to submit the final version of their paper, which will be included in the "proceedings to be distributed."

2. Present-and-publish acceptance
Authors of a submission with Present-and-publish acceptance will receive a "minor revision" decision from the IEEE ESL journal. The authors will be required to submit a revised version of their paper and a video graphical abstract (which is a short video presenting the paper), which will be reviewed in the second round. Once the final manuscript and the video graphical abstract are reviewed and meet IEEE ESL standards, the submission will receive an "accept" decision from the journal and will be included in the IEEE ESL special issue of TCRS.

See here for more information on the video graphical abstract: https://ieee-ceda.org/publication/esl/esl-paper-submission
