Why there is no description of the OpenCL library AVALON_MEM element for some signals? - Why there is no description of the OpenCL library AVALON_MEM element for some signals? Description The OpenCL programming advance guide explains about the RTL element required for the library for external memory. For the AVALON_MEM element defined in the code example, the corresponding RTL module ports are as follows: output avm_port0_enable, input [511:0] avm_port0_readdata, input avm_port0_readdatavalid, input avm_port0_waitrequest, output [31:0] avm_port0_address, output avm_port0_read, output avm_port0_write, input avm_port0_writeack, output [511:0] avm_port0_writedata, output [63:0] avm_port0_byteenable, output [4:0] avm_port0_burstcount, There is no assumed correspondence between pointers that you specify with MEM_INPUT and the Avalon-MM interfaces that you specify with AVALON_MEM. An RTL module can use a single pointer to address zero to multiple Avalon-MM interfaces Both signals in bold are not documented. Resolution In most applications the avm_port0_enable signal can be tied high, and the avm_port0_writeack signal can be ignored. An updated description will be included in the upcoming programming guide.
