SH7457

Description

The SH7457 and 7459 Groups are high-performance RISC microcontrollers embedded with an 32-bit SH-4A CPU core. & They have a maximum operating frequency of 240 MHz, CPU performance of over 432 MIPS, support single and double-precision floating point arithmetic operations, and achieve a maximum single-precision performance of 1.68 GFLOPS. & They incorporate enhanced communication functions required for in-vehicle networks, such as 4 channels of CAN and 2 channels of FlexRay. The SH7457 and SH7459 also incorporate camera interface functions required for in-vehicle camera control such as DRI interface (2 channels) and I2C-bus interface (1 channel), and components required for in-vehicle millimeter wave systems such as PDAC, PSEL, and DRI circuits, Timer unit TMU (3 channels), and multifunction timer unit ATU-IIIS (59 channels). Furthermore, an on-chip inter-board communication function for multi-CPU configurations enables higher performance driver-assist systems.

CAN Controller Usage: Applications and Frequently Asked Questions Rev.2.03
Log in to Download PDF 1.81 MB R01AN2535ED0203-CAN Rev.2.03 May 15, 2019
AI-generated Summary: The document details the Renesas CAN Controller's usage, including compatibility, evaluation results, and principles of pretended networking. It covers sample software descriptions, CAN driver functionalities such as initialization, configuration, transmission, reception, and diagnostics. The text also explains mapping of lower CAN drivers, application examples, and frequently asked questions addressing CAN conformance, transceiver issues, bit timing, operation modes, power save modes, transmission, reception, message storage, peripheral bus access, and interrupt handling.

RX Development Environment Migration Guide Migration from SuperH Family to RX Family (IDE ed.) (High-performance Embedded Workshop to CS+)
PDF 1007 KB REJ06J0102-0200 Rev.2.00 日本語 Apr 20, 2017
AI-generated Summary: The document explains key compiler option differences when migrating source code from the SuperH family to the RX family. It highlights that char types default to signed in SuperH but unsigned in RX, requiring the 'signed_char' option to maintain behavior. It also covers the 'auto_enum' option for automatic enum size selection and the 'dbl_size' option to specify double type size, which defaults to 4 bytes in RX compared to 8 bytes in H8 compilers. Configuration steps in the CS+ IDE are provided for each option.

Compiler Package Application Note: The application guide of Call Walker Rev.1.00
PDF 243 KB R20AN0294EJ0100 Rev.1.00 日本語 Feb 18, 2014
AI-generated Summary: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.

PDF 280 KB R20UT0075EJ0100 Rev.1.00 日本語 Jul 30, 2010
AI-generated Summary: The document details a comprehensive list of methods supported by the class in a compiler package. It covers various template functions such as swap, min, max, copy, fill, mismatch, equal, lexicographical_compare, count, find, search, replace, for_each, adjacent_find, remove_if, generate, unique, reverse, rotate, and random_shuffle. These methods facilitate operations on iterators and ranges, supporting comparisons, transformations, and searches with customizable predicates and binary operations.

PDF 478 KB R20UT0074EJ0100 Rev.1.00 日本語 Jul 30, 2010
AI-generated Summary: This section explains how to set up the STL (Standard Template Library) environment for RXC or SHC compilers. It details two methods to add the STL include directory: through the HEW toolchain's Options dialog box and via command line by setting environment variables or compiler include options. Step-by-step instructions guide users to specify the STL directory, ensuring the STL becomes available for building projects.
