Hence, we need circuits capable of performing floating-point operations on a wide range of precisions with high energy-proportionality. We present FPnew, a highly configurable open-source transprecision floating-point unit (TP-FPU) capable of supporting a wide range of standard and custom FP formats. To demonstrate the flexibility and efficiency of FPnew in general-purpose processor architectures, we extend the RISC-V ISA with operat","authors_text":"Fabian Schuiki, Florian Zaruba, Luca Benini, Stefan Mach","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AR","submitted_at":"2020-07-03T07:38:00Z","title":"FPnew: An Open-Source Multi-Format Floating-Point Unit Architecture for Energy-Proportional Transprecision Computing"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2007.01530","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:305d2b5bc9fe203635834b04c845e4adaad0d5a4dac0cab1370ab3a435707891","target":"record","created_at":"2026-07-05T01:16:02Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"b8046804de5609090e88c3dfa17a25ffe955cd975a4f95691cc61d50428ee803","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AR","submitted_at":"2020-07-03T07:38:00Z","title_canon_sha256":"c7c53bab2cc5108845a0fd2de78beb34e23e5e8e679f9b05029b68c5031be3dc"},"schema_version":"1.0","source":{"id":"2007.01530","kind":"arxiv","version":1}},"canonical_sha256":"23029abcce072ff55af44980028a9abdbb68a84007d022d1862df32aa8583edc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"23029abcce072ff55af44980028a9abdbb68a84007d022d1862df32aa8583edc","first_computed_at":"2026-07-05T01:16:02.523691Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:16:02.523691Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8DmzvQhFo8KT1jsROOcBicW+JXtn9F5ebz6KRl6h3LhuIwbixE04q+ICm8q9K5ssOrzyQzYYsBhFcmcDarytAw==","signature_status":"signed_v1","signed_at":"2026-07-05T01:16:02.524153Z","signed_message":"canonical_sha256_bytes"},"source_id":"2007.01530","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:305d2b5bc9fe203635834b04c845e4adaad0d5a4dac0cab1370ab3a435707891","sha256:661a03ed67ae46e64421a05019ee2732afdec9607aa1d4a32aaffb5451a8f77e"],"state_sha256":"f15e345bbf049cd75ae1efb5d2ae369d859cbc0104093793deb4bcc5505cd643"}
