sapphire r7

1. System calls are required from user space to kernel space2. The system call is implemented via the SWI instruction, at which point a parameter is stored in the R7 register to specify the kernel function to invoke.3. The actual functions of the general kernel State can be implemented in arbitrary. c files, but the corresponding function pointers must be added to the CALL.S (add table entries)4. Also declare the parameters in the Unistd.h. This param

directive invokes the system routine of the operating system number bit 02The way Linux 2.6.16 is used later:The 24-bit immediate number in the instruction is ignored, the service type requested by the user is determined by the value of the register R7, and the parameters are passed through the other general registers. For example:MOV R7, #12SWI 0Each system call has a unique system call function number Al

CORTEX-M3 has universal register R0-R15 and some special function registers. R0-r12 is the most "common purpose", the vast majority of 16-bit instructions can only use R0-R7, while the 32-bit Thumb-2 instruction has access to all the universal registers. Special function registers must be accessed through a dedicated instruction.Universal Purpose Register R0-R7R0-R7 is called a low group register. All instr

current setup," she said. "Her employees have transformed data warehouses from Oracle databases to DB2 Universal database. This change saves money and DB2 performance, with excellent vendor support. "But it also affects some IT staff. "If the price of DB2 is significantly lower than Oracle, we will consider it more carefully," she said. But we also have to consider the cost of retraining our employees and hiring contractors. ” Spang did not disclose the package prices, customers can purchase
