z80 instruction set

Here we will briefly describe several important arithmetic operation commands. 1. Horizontal addition command The ssse3 Instruction Set adds commands that add integers horizontally, similar to the floating point commands of sse3. Phaddd Add a 32-bit unsigned integer in the horizontal direction of the Register Phaddw Add the registers horizontally according to the unsigned 16-bit integer

MRS and MSR InstructionsThe status flag in the MRS (move PSR to general-purpose Register) procedure status register (program state REGISTER,PSR) is read into the Universal Register, MSR (move general-purpose Register to PSR) writes the flag to the program status register. These two instructions can be used in the current program status register (CPSR) or in the Saved program status register (SPSR). For example:MRS R0, Cpsrmrs R1, SPSRMSR PSR, R7BIC directivesThe BIC is used to place the specifie

Only VS2002 and above support the SSE command function library Currently, most CPUs (Intel and AMD) on the market support the SSE instruction set. The SSE command function must contain the following header files: # Include The details of the SSE command are not described in detail here. Here we only talk about the batchcompute function. However, this batch operation only processes four 32-bit characters

The processor uses the ARMv6-M thumb instruction set, including a large number of 32-bit instructions using the thumb-2 technology. Table 7-22 lists the Cortex-M0 instructions and their cycles. The cycle count is based on the system in the Zero Wait state. Table 7-22 Cortex-M0 instructions and their cycles Operation Description Sort order Weekly Move 8-bit immediate Movs Rd,

application cannot directly write r700 local memory, but it can command r700ProgramAnd data are copied between system memory and r700 memory. There are two methods for writing CPU to GPU memory: 1. Request the DMA engine of the GPU to write data to it by pointing to the location of the source data on the CPU memory, and then pointing to the offset in the GPU memory to be written. 2. Load a kernel and run it on the shader. The shader accesses the memory through the PCIe connection, processes
