The MIPS32® 4KSd™ secure data core is a high-performance processor that meets the needs of emerging secure data applications and the stringent power, security and size requirements for smart cards. This core has the performance required to implement software programmable cryptography without the need of a coprocessor, reducing SoC size and power consumption. The 4KSd core is the most secure, licensable, 32-bit processor available.

With the 4KSd core, extensive security features disguise processor activity, resist external attacks and prevent tampering through power analysis and other techniques. MIPS Technologies’ cryptography enhancements speed public- and secret-key cryptography algorithms for data security without additional dedicated hardware or coprocessor modules, and secure memory spaces protect sensitive consumer data by application and prevent unauthorized data access by rogue applications.

CorExtend™ capabilities allow expert designers to further differentiate their secure SoC applications by adding their own instructions to create unique security features. Low interrupt latency allows the core to respond more quickly to external events, and MIPS16e™ code-compression allows usage of smaller memories, reducing power consumption and die size. The 4KSd core is based on the enhanced MIPS32 industry-standard architecture, supported by hundreds of third-party development tools and applications.
