I'm only looking for any corrections to my existing ARMv8 code. This is the C program I'm basing it off of: These are the project requirements (note the registries used for sum, smallest, and largest): In AArch64, PC relative symbol references are emitted using adrp/add or adrp/ldr pairs, where the offset into a 4 kB page is resolved using a separate :lo12: relocation. This implicitly assumes that the code will always be executed at the same relative offset with respect to a 4 kB boundary, or the references will point to the wrong address.
smc_handler64: /* NOTE: The code below must preserve x0-x4 */ /* * Save general purpose and ARMv8.3-PAuth registers (if enabled). * If Secure Cycle Counter is not disabled in MDCR_EL3 when * ARMv8.5-PMU is implemented, save PMCR_EL0 and disable Cycle Counter.
SiFive RISC-V processors are powering flash drives in production as well as addressing emerging In-Storage Computing (ISC) needs. In the current digital age, where data powers increasing levels of decision making, industrial control and automation, efficient data storage, movement, and processing become the focal point of technological innovations in silicon, system, and software.
The A64 instruction set is supported by the Armv8-A architecture. Key features of A64 include: Clean decode table based on 5-bit register specifiers. Instruction semantics broadly similar to A32 and T32. 31 general-purpose 64-bit registers accessible at all times. No modal banking of general purpose registers for improved performance and energy. Describe below what the code does.
